About This Guide Congratulations and thank you for purchasing an ioSafe disaster proof backup and storage system from ioSafe Inc. This ioSafe system represents the latest technology in disaster-proof computer hardware. Chapter 1, “FrontView Advanced Control”, describes all the menus and tabs available in the Advanced Control mode. If you have already configured the ioSafe R4 and you need help in accessing the shares on the ioSafe R4, skip to Chapter 2, “Accessing Shares”.
1 Chapter FrontView Advanced Control The Advanced Control mode offers the all settings available in the Setup Wizard plus more. When you first switch to this mode, you’ll see the menus on the left that allow you to quickly jump to the desired menu page. Towards the bottom left, you’ll notice buttons that allow you to switch back and forth between the Setup Wizard mode and the Advanced Control mode. As you click on the menu buttons, you’ll notice a similar theme across all menu pages.
At the furthest bottom is the status bar with the date button which doubles its duty as a clock and a link to the Clock page. The status LEDs to the right gives a quick glimpse of the system device status. The statuses represent: Not present – No disk or device attached. Normal – Device in normal operating mode. If the LED is blinking, this disk is currently re-syncing.
Move the mouse cursor over the LED to display more information on the device, or click on it to display the status in more detail. Right above the status bar is the action bar. To the left are the Advanced Control and Setup Wizard buttons. To the right is the Apply button. Use this to save any changes in the current menu page.
Network Ethernet The Ethernet tab allows you to specify network interface-specific settings. In the Standard Setting box, you can specify the IP address, network mask, speed/duplex mode, and MTU settings. In most networks where a DHCP server is enabled, you can simply specify the “Use values from a DHCP server” option to automatically set the IP address and network mask.
Note If you elect to assign the IP address using DHCP, it is advisable to set the lease time on the DHCP server/router to a value of at least a day. Otherwise, you may notice that the ioSafe R4 IP address may change even when it has been powered down for only a few minutes. Most DHCP servers allow you to assign a static IP address for specified MAC addresses. If you have this option, this would be a good way to ensure your ioSafe R4 maintains the same IP address even in DHCP mode.
Warning Do not enable VLAN support unless you are sure your clients also support VLAN. Otherwise, you can lose network access to the ioSafe R4 and you may need to perform a firmware re-installation to disable the VLAN setting. ► PERFORMANCE SETTING The Enable jumbo frames option allows you to optimize the ioSafe R4 for large data transfers such as multiple streams of video playback. Select this option if your NIC and your gigabit switch support jumbo frames.
Global Network Settings ► HOSTNAME The Hostname you specify is used to advertise the ioSafe R4 on your network. You can use the hostname to address the ioSafe R4 in place of the IP address when accessing the ioSafe R4 from Windows, or over OS X using SMB. This is also the name that will appear in the RAIDar scan list. The default hostname is nas- followed by the last three bytes of your primary MAC address.
If you had selected the DHCP option in the Ethernet tab, the domain name server fields will be automatically populated with the DNS settings from your DHCP server. If you had selected the Static option, you can manually specify the IP addresses of the DNS servers and the domain name here. WINS The WINS option allows you to specify the IP address of the WINS (Windows Internet Naming Service) server.
DHCP The DHCP tab allows this device to act as a DHCP (Dynamic Host Configuration Protocol) server. DHCP service simplifies management of a network by dynamically assigning IP addresses to new clients on the network. Click on the Enable DHCP service checkbox if you want the ioSafe R4 device to act as a DHCP server. This is convenient in networks where DHCP service is not already available. Note These options are available only if this device is not already using a DHCP address.
Route The Route tab is available if you have two or more network interfaces (Ethernet or Wireless combined) on your ioSafe R4. In some environments, you can optimize your network traffic by manually setting up a routing table. Route table management is beyond the scope of this manual, and this option is provided only for advanced users who understand routing and wish to deviate from the default routes.
Security Admin Password The Admin Password tab allows you to change the admin user password. The admin user is the only user that can access FrontView and this user has administrative privileges when accessing shares. Be sure to set a password different from the default password and make sure this password is kept in a safe place. Anyone who obtains this password can effectively change or erase the data on the ioSafe R4. The default admin user password is “iosafe1” .
Security Mode Selection The ioSafe R4 device offers three security options for your network environment. Read the quick overview below to help select the most appropriate option based on the required level of security and your current network authentication scheme. The Share security mode is suitable for most home and small office environments, providing a simple way for people in a trusted environment to share files without the necessity of setting up separate user and group accounts.
Note The FrontView management system will slow down in proportion to the number of users in the domain. It is not advisable to use the ioSafe R4 in a domain environment with more than 1000 users. Share Security Mode The Share security mode is the easiest security option to set up. ► SPECIFY A WORKGROUP You only need to specify a workgroup if you wish to change it from the default.
Note Private user shares are only accessible by users using CIFS (Windows) or AppleTalk file protocols. To set up the ioSafe R4 for this security mode, you will need the following information: Workgroup name Group names you wish to create (i.e.
► MANAGING GROUPS To add a new group, click on the Add Group tab if it is not already selected. You can add up to five groups at a time. If you expect to have just one big set of users for one group, you can forego adding a new group and accept the default users group. If desired, a user can belong to multiple groups. Once you have created user accounts, you can specify secondary groups that the user can belong to. This allows for finer-grain settings for share access.
After adding your groups, you can view or change your groups by clicking on the alphabetical index tab, or All to list all groups. If you wish to add a large number of groups, select Import group list from the selection box.
Here, you can upload a CSV (Comma Separated Value) formatted file containing the group account information. The format of the file is: name1,gid1,quota1,member11:member12:member13 name2,gid2,quota2,member21:member22:member23 name3,gid3,quota3,member31:member32:member33 Please note the following: Spaces around commas are ignored. The name fields are required. Quota will be set to default if not specified. GID will be automatically generated if not specified.
► MANAGING USERS To manage user accounts, select the Manage users option in the drop-down box. To add a user, click on the Add User tab. You can add up to five users at a time. You can enter a user name, email address, user ID, select a group, password, and disk quota for the user. Only the user name and password fields are required, however, you should specify the user email address if you intend to set up disk quotas.
Here, you can upload a CSV (Comma Separated Value) formatted file containing the user account information. The format of the file is: name1,password1,group1,email1,uid1,quota1 name2,password2,group2,email2,uid2,quota2 name3,password3,group3,email3,uid3,quota3 Please note the following: Spaces around commas are ignored. The name and password fields are required. If a listed group account does not exist, it will be automatically created.
In this example, user barney will have password set to 23stone, belongs to the default group, will be sent email notification to barney@bedrock.com, automatic UID assigned, and default quota. wilma,imhiswif,ourgroup,wilma@bedrock.com,225,50 In this example, user wilma will have password imhiswif, belongs to group ourgroup, email notification sent to wilma@bedrock.com, UID set to 225, and quota set to 50MB.
Domain Security Mode ► DOMAIN/ADS AUTHENTICATION If you choose the Domain security mode option, you will need to create a trusted relationship with the domain controller or the active directory server (ADS) that will act as the authentication server for the ioSafe R4 device. You will need the following information: Domain name Domain administrator login Domain administrator password If using ADS: - DNS name of the ADS realm - OU (Organization Unit).
If you have a large number of users in your domain, you may need to deselect the Display users from trusted domains… checkbox. Otherwise, FrontView management system may slow down to an unusable state. Note Use of the ioSafe R4 in a domain environment with more than 1000 users is not recommended at this time. Click Apply to join the domain. If successful, users and groups from the domain will have login access to the shares on this device.
Services The Services menu allows you to manage various services for share access. This in effect controls the type of clients you wish to allow access to the ioSafe R4. You will notice three tabs at the top: Standard File Protocols, Streaming Services, and Discovery Services. These different services are explained below.
CIFS (Common Internet File Service). Sometimes referred to as SMB. This protocol is used mainly by Microsoft Windows clients, and sometimes used by Mac OS X clients. Under Windows, when you click on My Network Places or Network Neighborhood, you’re going across CIFS. This service is enabled by default and cannot be disabled. NFS (Network File Service.) NFS is used by Linux and Unix clients. Mac OS 9/X users can access NFS shares as well through console shell access.
SquezeCenter (SlimServer) provides music streaming to the popular Squeezebox music players from Slim Devices. iTunes Streaming Server enables iTunes clients to stream media files straight from the ioSafe R4. UPnP AV provides media streaming service to stand-alone networked home media adapters and networked DVD players that support the UPnP AV protocol or are Digital Living Network Alliance (DLNA) standard compliant.
Home Media Streaming Server provides streaming of videos, music, and pictures to popular networked DVD players. The streaming players often utilize the streaming client developed by Syabas. Similar to UPnP AV, this service is used to stream videos, music, and pictures from the reserved media share to these adapters. If you wish to change the location where the media files are stored, you can specify a different share and folder path. Note that this path is shared between the UPnP AV and this service.
Volumes Volume Management The ioSafe R4 consists of two RAID volume technologies – Flex-RAID, utilizing the industrystandard RAID levels 0, 1, and 5, and X-RAID, NETGEAR-patented expandable RAID technology. Your system defaults to X-RAID, however, you can switch between the two modes through a factory default reset process described in Chapter 4 – System Reset Switch. There are advantages to both technologies. ► ADVANTAGES OF FLEX-RAID 1.
► DELETING A VOLUME To delete a volume, click on the volume tab of the volume you wish to delete or Volume C if only one volume is configured. Make sure if you have data in that volume that you back up the files you wish to keep first. All shares, files, and snapshots residing on that volume WILL BE DELETED AND ARE NON-RECOVERABLE! Click Delete Volume in the Volume C tab.
► ADDING A VOLUME You will then be presented with the Add Volume tab listing the available configurable space on the hard disks. All the disks will be selected by default. You can elect to specify a hot spare disk if you wish. A hot spare remains in standby mode and will automatically regenerate the data from a failed disk from the volume. A hot spare disk is only available for RAID level 1 and RAID level 5 if there are enough disks to fulfill the required minimum plus one.
allocate enough space for worse case as the snapshot becomes unusable when its reserved space runs out. In our example above, we selected 50GB of the volume to be reserved for snapshots. Specify desired volume size After you’ve specified the above volume parameters, enter the desired volume size if you wish to configure a smaller volume size than the maximum displayed. The resulting volume will be approximately the size that is specified. In our example above, we kept the maximum size that was calculated.
We can also remove a disk from the volume by clicking on the Remove button. The volume will still be available but in a non-redundant state. An additional disk failure would render this volume unusable. Warning The Remove operation is a maintenance feature and is not recommended in a live environment. Its function is equivalent to hot-removing the disk or simulating a disk failure. The Locate option is a way to verify that a disk is correctly situated in the expected disk slot.
► X-RAID HAS ONE DATA VOLUME X-RAID devices only have one data volume. This volume encompasses one to four disks, utilizing the capacity of the smallest disk from each disk. For instance, if you had one 80GB disk and two 250GB disks, only 80GB from each disk will be used in the volume. (The leftover space on the 250GB disks will be reclaimed only when the 80GB disk is replaced with a 250GB or greater capacity disk. See “Replacing All Your Disks for Even More Capacity” below.
Once you get the completion notification for the 4th disk, reboot the ioSafe R4. During boot, volume capacity is expanded with the additional capacity from each disk. For instance, if you had replaced four 250GB disks with four 600GB disks, the capacity of the volume will increase by approximately 350GB x 3 (the fourth disk is reserved for parity). The expansion process will take several hours depending on the capacity expanded, and you will be notified by email when the process is complete.
Specify the frequency and the days that you wish to schedule a snapshot. A start and end-time of 00:00 will take one snapshot at midnight. A start time of 00:00 and end-time of 23:00 will take snapshots between midnight and 11pm the next day at the interval you specify. Once you save the snapshot schedule, the time of the next snapshot will be displayed. When the next snapshot is taken, the previous one is replaced. If you prefer, you can manually take a snapshot – just click on Take snapshot now.
You can also specify how long a snapshot should last. If you will be using snapshots for backups, you can schedule the snapshot to last slightly longer than the expected duration of the backup. Having an active snapshot can affect the write performance to the ioSafe R4, so deactivating it when not needed may be advantageous in write-intensive environments.
You can traverse a snapshot share just as you would a normal share except that the snapshot share is read-only. If you wish, you can select a detailed listing to show the snapshot time in the description field. Snapshots can expire when the snapshot reserved space is filled. The snapshot mechanism keeps track of data that has been changed from the original volume starting at the point when the snapshot is taken. All these changes are kept in the snapshot reserved space on the volume.
The process of resizing the snapshot space can take awhile depending on your data volume size and the number of files in your volume. Expanding the snapshot space will reduce your data volume size, and reducing the snapshot space will expand it. Note Due to the nature of how snapshots work, you will encounter a drop in write performance when a snapshot is active.
Partitions on the storage devices must be one of the following file system formats: FAT32 NTFS Ext2 Ext3 To the right of the access icons are command options for the device. The following commands are available: Disconnect: This option prepares the USB partition for disconnection by properly unmounting the file system.
can be retained using this format whereas this capability is not there with FAT32. Although not natively present in the base operating system, Ext3 support for Windows and OS X can be added. The installation images can be downloaded from the web. When the USB device is unmounted, you have the option of renaming it. The next time the same device is connected, it will use the new name rather than the default USB_FLASH_n or USB_HDD_n naming scheme.
Shares The Shares menu provides all the options pertaining to share services for the ioSafe R4 device. This entails share management (including data and print shares), volume management, and share service management. We’ll first look at how we can control the services. Adding Shares To add a share, click on the Volume tab. If more than one volume is configured, click on the volume you wish to add the share. The Add Share tab has two looks, depending on the security mode.
In either case, you can add up to five shares at a time. Once you finish adding the shares, you can refer to Chapter 2 for instructions on how to access them from different client interfaces. Managing Shares Once you have added shares, you may want to manually fine-tune share access in the Share List tab. This tab has two looks, one for Share security mode and one for User and Domain mode. They’re both similar except for the password and disk quota prompts which only appear in Share mode.
If you want to delete a share, click on the checkbox to the far right of the share listing and click Delete. You have the option of deleting up to five shares at a time. The columns to the left of the Delete checkbox represent the services that are currently enabled, and the access icons in those columns summarize the access rights to the share for each of the services. You can move the mouse pointer over the access icons to get a quick glimpse of the access settings.
that are granted read/write permission, or (3) access is disabled except for one or more users or groups that are granted read-only privilege. Write Access with exceptions – Either (1) access to this share is read/write and only allowed for specified hosts, (2) access is read/write except for one or more users or groups that are restricted to read-only access, or (3) access is disabled except for one or more users or groups that are granted read/write privilege.
In this tab, you can select the default access at the top and optionally specify the host(s) that you wish to allow restrict access to in the Share Access Restriction box. Share Access Restriction For instance, select read-only for default access and list the hosts you wish to allow access to. Access from all other hosts will be denied. For example, to allow only host 192.168.2.101 read-only access to the share, specify the following: Default: Hosts allowed access: Read-only 192.168.2.
► SETTING SHARE ACCESS IN USER AND DOMAIN MODES In User or Domain modes, the same tab would look as follows (note the addition of read-only and write-enabled user and group fields):
Share Access Restriction If you wish to limit share access to particular users and/or groups, you can enter their names in the Read-only users, Read-only groups, Write-enabled users, and Write-enabled group fields. The names must be valid accounts, either on the ioSafe R4 or on the domain controller.
You can specify how long to keep the files in the Recycle Bin and how large the Recycle Bin can get before files get permanently erased. Advanced CIFS Permission The Advanced CIFS Permission box offers options for setting the default permission of new files and folders created via CIFS. The default permission of newly created files is read/write for the owner and owner’s group and read-only for others (i.e. everyone). Permission for newly created folders is read/write for everyone.
► ADVANCED OPTIONS The Advanced Options tab offers advanced low-level file manipulation options that can affect remote file access through all file protocol interfaces. Care should be taken before using these options as anything that changes ownership and permissions may not be easily reversible.
USB Shares USB storage devices are shared using the name of the device appended by the partition number. The base device name can be changed in the Volumes/USB tab if desired. The ioSafe R4 attempts to remember the name as long as there’s a unique ID associated with the USB device so that the next time the device is connected, the same share name(s) will be available. Share access restrictions are not saved across disconnects, however.
Printers The ioSafe R4 device supports automatic recognition of USB printers. If you have not already done so, you can connect a printer now, wait a few seconds, and click Refresh to display detected printers. The print share name will automatically reflect the manufacturer and model of your printer and will list in the USB Printers tab. Print Shares over CIFS/SMB The ioSafe R4 can act as a print server for up to two USB printers for your Windows or Mac clients.
Double-click the printer icon to assign a Windows driver. IPP Printing The ioSafe R4 also supports the IETF standard Internet Printing Protocol (IPP) over HTTP. Any client supporting IPP Printing (IPP is available natively on the latest Windows Versions and OS X) can now use this protocol to utilize printers connected to the ioSafe R4. The simplest way to utilize IPP Printing is to use Bonjour to discover and setup the print queue.
Backup The Backup manager integrated with the ioSafe R4 allows the ioSafe R4 to act as a backup appliance. Backup tasks can be controlled directly from the ioSafe R4 without the need for a clientbased backup application. With the flexibility to support full and incremental backups across FTP, HTTP, CIFS/SMB, and NFS protocols, the ioSafe R4 can act as a simple central repository for both home and office environments.
► STEP 1 – SELECT BACKUP SOURCE The backup source can be located remotely or it can be a public, a private home share, or all home shares on the ioSafe R4. A USB device will appear as a share, so if you want to backup a USB device, select on a share name starting with USB. If you want to backup data from a remote source, you will need to select from one of the following: Windows/NAS (Timestamp) – select this if you wish to backup a share from a Windows PC or another ioSafe R4 device.
Windows/NAS (Archive Bit) – select this if you wish to backup a share from a Windows PC. Incremental backups use the archive bit of files, similar to Windows, to determine whether they should be backed up. Website – select thi if you wish to back up a website or a website directory. The backed up files include files in the default index file and all associated files, as well as all index file links to web page image files.
With a remote source, you may need to enter a login and password to access the share. If you are accessing a password-protected share on a remote ioSafe R4 server configured for Share security mode, enter the name of the share name for login. You should click on the Test Connection button to make sure you have proper access to the remote backup source before continuing.
Schedule full backup First, select when you want full backups to be performed. You can elect to do this just at the first time, every week, every two weeks, every three weeks, every four weeks, or every time this backup job is invoked. The first full backup is performed at the next scheduled occurrence of the backup depending on the schedule you specify, and the next full backup is performed at the weekly interval you choose calculated from this first backup.
Change ownership of backup files The Backup Manager attempts to maintain original file ownership whenever possible; however, this may cause problems in Share security mode when backup files are accessed. To work around this, you have the option of automatically changing the ownership of the backed up files to match the ownership of the share. This allows anyone who can access the backup share to have full access to the backed up files.
Click View Logs to check a detailed status of the backup. Click Clear Logs to clear the current log detail. Programming the Backup Button On ioSafe R4 systems you can program the backup button to execute one or more pre-defined backup jobs. Simply select the backup jobs in the order that you want them run and click Apply. Pressing the Backup Button once will start the job(s). Viewing the Backup Log You can view the backup log while the job is in progress or after it has finished.
System To set up and manage your ioSafe R4 system effectively, review the settings in the following sections and make any necessary changes. Clock An accurate time setting on the Clock screen is required to ensure proper file timestamps. You can access the Clock screen by selecting System > Clock from the main menu. ► SYSTEM TIME The System Time tab in the Clock page allows you to set the date, time, and time zone. Set appropriately to ensure files maintain proper timestamp.
Alerts ► ALERTS CONTACTS The Contacts tab allows you to specify up to three email addresses where system alerts will be sent. The ioSafe R4 device has a robust system monitoring feature and sends email alerts if something appears to be wrong or when a device has failed. Make sure to enter a primary email address and a backup one if possible. Some email addresses can be tied to a mobile phone. This is a great way to monitor the device when you are away from your desk.
► ALERTS SETTINGS This ioSafe R4 device has been pre-configured with mandatory and optional alerts for various system device warnings and failures. The Settings tab allows you to control the settings for the optional alerts. It is highly recommended that all alerts are kept enabled; however, you may choose to disable an alert if you are aware of a problem and wish to temporarily disable it. At bottom of the tab, under the Other Alert Settings heading, you’ll notice a couple additional options.
► SNMP If you utilize a SNMP management system such as HP OpenView or CA UniCenter to monitor devices on your network, you can set up the ioSafe R4 device to work within this infrastructure. To set up SNMP service, check the Enable SNMP service checkbox in the SNMP tab. You can leave the Community name as public, or specify a private name if you have opted for a more segregated monitoring scheme. Next, enter a host name or an IP address for Trap destination. This is where all trap messages will be sent.
► SMTP The ioSafe R4 system has a built-in email message transfer agent (MTA) that is set up to send alert email messages from the device. Some corporate environments, however, may have a firewall that blocks untrusted MTA’s from sending out messages. If you were unable to receive the test message from the Alerts Settings tab, it may have been blocked by the firewall. In that case, specify an appropriate SMTP server in this tab. Internet Service Providers (ISP) for home may also block untrusted MTA’s.
Performance If you wish to tweak the system performance, select the Performance tab in the System menu. Note that some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before enabling that option. Select Disable full data journaling to substantially improve disk write performance.
The Optimize for OS X option provides the best performance in Mac OS X environments when connected to the ioSafe R4 through the SMB/CIFS protocol. This option however introduces compatibility issues with Windows NT 4.0; do not enable this option if this device will be accessed by Windows NT 4.0 clients. The Enable fast CIFS writes option allows for fast write performance by enabling aggressive write-back caching over CIFS.
Language The Language tab offers the option of setting the ioSafe R4 device to the appropriate character set for file names. For example, selecting Japanese allows sharing of files with Japanese names in Windows Explorer.
It is best to select the appropriate language based on the region that this device will operate in. Note This option does not set the web browser language display – browser settings must be done using the browser language option. Unicode for User, Group, and Share Names If desired, you can elect to enable use of Unicode for user, group, and share names, allowing for greater flexibility in non-English speaking regions. This option, once selected, cannot be reversed.
Simply click Check for Update to check for updates on the ioSafe update server. If you wish to continue, click Perform System Update. After the update image has been downloaded, you will be asked to reboot the system. The update process only updates the firmware image and does not modify your data volume. However, it is always a good idea to backup your important data whenever you perform an update.
► LOCAL UPDATE When the ioSafe R4 device is not connected to the Internet, or Internet access is blocked, you can download an update file from the Support site and upload that file to the ioSafe R4 in the Local update tab. Click on the Browse button to select the update file and click the Upload and verify image button. The process will take several minutes at which time can click the Perform System Update button. You will be requested to reboot the system to proceed with the upgrade.
► SETTINGS If you do have reliable Internet connection, you can enable the automatic update check and download options in the Settings tab. If you enable the Automatically check for updates option, the ioSafe R4 will not download the actual firmware update, but will notify you when an update is available. If you enable the Download updates automatically option, the update image will be downloaded, and you will be notified by email to reboot to the device to perform the update.
Warning Resetting to Factory Default will erase everything, including data shares, volume(s), user and group accounts, and configuration information. There is no way to recover after you confirm this command.
Power Management The ioSafe R4 offers a couple of power management options to reduce the system’s power consumption while it is in use and when it is expected to not be in use. ► DISK SPIN-DOWN OPTION You can elect to spin-down your ioSafe R4 disks after a specified time of inactivity. The disks will spin-up as needed.
Note Enabling disk spin-down will disable journal mode. Once enabled, if you decide to disable disk spin-down, you will need to manually re-enable journal mode if desired. A UPS is recommended if you utilize this option. ► POWER TIMER The ioSafe R4 can be scheduled to power off and power back on automatically. Select the Enable power timer checkbox and enter the desired action and time.
Shutdown The Shutdown tab offers the option to power-off or reboot the ioSafe R4 device. You have the option of performing a full file system check or quota check on the next boot. Both these options can take several minutes to several hours depending on the size of your volume and the number of files in the volume. You do not need to select these options unless you suspect there might be data or quota integrity problems.
Status The Status page consists of the Health and Logs tabs providing system status information. Health The Health page displays the disk, fan, power, temperature, and UPS status in detail. When available, normal expected values are provided. For disks, you can click on the SMART+ (Self-Monitoring, Analysis and Reporting Technology) button to display the content of the internal disk log.

2 Chapter Accessing Shares This chapter presents examples of how shares on the ioSafe R4 device can be accessed by the various operating systems. If you have problems accessing your shares, make sure to enable the corresponding service in the Shares Services tab. Also make sure the default access of the share is set to Read-only or Read/write.
Windows To see a share listing under Windows, either click Browse in RAIDar or enter \\hostname or \\ip_address in the Explorer address bar. Hostname is the NAS hostname assigned in the Network tab. The default hostname is set to nas- followed by the last three hex bytes of the device MAC address. To access the share under Windows, specify the hostname followed by the share name in the Explorer address bar, i.e.
MAC OS X To access the same share over AFP with OS X, select Network from the Finder Go menu. At this point, there are two ways in which you can access your AFP share, depending on how you have chosen to advertise your AFP share. AFP over Bonjour To access the AFP share advertised over Bonjour on Mac OS X, select Network from the Finder Go menu to see a listing of available networks. Open the My Network folder to display the ioSafe R4 hostname.
Double-click on the hostname icon to display the share listing. In Share security mode, simply select “Guest” to access the shares. In User or Domain security mode, enter the user name and password you wish to connect to the ioSafe R4 as.
Select the Share you would like to view. AFP over AppleTalk If you had chosen to advertise your AFP service over AppleTalk, you will see a listing of available networks. Open the My Network folder to display the ioSafe R4 hostname. Select the one that has the hostname only. You’ll be prompted with a connection box.
Select Guest and then the share you wish to connect to, and click OK. In Share security mode, you will need to only specify user name and password if you have set up a password for your share. Enter the share name in place of the user name. In User or Domain security mode, enter the user name and password you wish to connect to the ioSafe R4 as. You should see the same file listing as you would in Windows Explorer.
MAC OS 9 To access the same share under Mac OS 9, select Connect to Server from the Finder menu, choose the NAS device entry from the AppleTalk selection, and click Connect. When you are prompted to login, enter the share name and password if the ioSafe R4 is configured for Share security mode, or enter a valid user account and password otherwise, and click Commect. If no share password is set in Share mode, you can select Guest user and leave the password field blank.
You should see the same files in the share that you do under Windows Explorer.
Linux/Unix To access this share from a Linux or Unix client, you will need to mount the share over NFS, i.e. type: mount ipaddr:/backup /backup where backup is the share name. Running the ls command in the mounted path displays the share content. Note The ioSafe R4 does not support NIS as it is unable to correlate NIS information with CIFS logins.
Web Browser To access the same share using a web browser, enter http://ipaddr in the browser address bar. You can use https if you want a secure encrypted connection. You will be prompted to login. Enter the share name and share password if the ioSafe R4 is in Share security mode. Otherwise, login with a valid user and password if the ioSafe R4 is in User or Domain mode.
If the share access is read-only, the file manager will only display: If the share is also writable, the file manager will have options for creating, modifying, and deleting files, as follows: One useful application for a web share is for setting up an internal company website. You can copy HTML files to the web share using Windows, Mac, NFS, or HTTP. When you set HTTP access to read-only, html files, including index.htm and index.html, can be viewed using any web browser.
FTP / FTPS To access the share via FTP in Share security mode, use “anonymous” as the login and your email address as the password. Note Enabling FTP access in Share mode opens up the share to anyone who has an FTP client on your network. It is best to enable FTP access only to shares you are comfortable making public on your network. Warning Disk usage using FTP in Share mode does not count towards the share disk quota, so carefully choose how you advertise a FTP Share.
Rsync Access to the share via rsync is identical regardless of the security mode. If you had specified a user or password in the rsync share access tab, you will need to specify this when accessing the rsync share. Unlike other protocols, rsync uses arbitrary user name and password that is specific only for rsync access. The user account you specify does not need to exist on the ioSafe R4 or a domain controller.
Networked DVE Players and UPnP AV Media Adapters Networked DVD players and UPnP AV Media adapters will detect the ioSafe R4 if the Home Media Streaming Server or the UPnP AV services are enabled. The content of the Streaming Services media share on the ioSafe R4 is available to these players for playback. Please consult the player manual for information on the file formats that it supports. Multiple players can be connected to the ioSafe R4 and can play the media files concurrently.
3 Chapter Replacing a Failed Disk Locate the Failed Disk When a disk fails in your ioSafe R4 device, you will be notified of the failure by email. The failed disk location can be seen in the FrontView status bar at the bottom. If you look at the front of the ioSafe R4 device, the failed disk will have also have a corresponding LED which will be amber in color. The top or left-most LED is disk channel 1; the next one is disk channel 2; and so on. Please take note of the failed channel.
On the ioSafe R4 system open up the front vent door using the four thumbscrews on the front of the unit. All the disk positions are labeled accordingly, identify which disk needs to be replaced. Remove the failed disk, wait approximately 30 seconds, then install the replacement disk and replace the front vent door. The front vent door can only be attached in one orientation. If the door doesn’t seem to fit, try rotating the door to a different orientation.
Fire Damage: Moderate –Deformation of plastic parts due to heat. Minor areas of discoloration or paint damage. Doors easy to remove. Extreme – Extensive paint damage, plastic parts are completely melted or gone, structural components appear visibly warped or compromised. Doors are difficult to remove. Water/moisture exposure: Moderate – Exposure to moisture or liquid for a short period of time due to splash, spray or flood. The R4 has minimal moisture present and no corrosion on the connectors.
10) Connect the AC power cable (P/N: 455-10370-00) to the recovery core, then connect the other end to AC power. Be aware that the recovery core will immediately initiate boot when the power cable is connected. 11) Verify LEDs are flashing during power up. Verify 4 solid green lights indicate all 4 hard drives have booted. Verify one solid blue light to indicate the core has properly booted. Two flashing green lights may indicate drive activity and network activity.
4 Chapter System Reset Switch The System Reset switch on the front of the ioSafe R4 next to the power button. The System Reset switch allows you to perform three functions: (1) re-install the ioSafe R4 firmware, (2) reset the ioSafe R4 back to the factory default settings, and (3) change between XRAID and Flex-RAID mode. Typically, you should not need to resort to options (1) and (2) unless you have exhausted all other means of recovering your system.
Setup in the Info column. It may take a couple of minutes for RAIDar to display this. At this point, click the Setup button to enter the Volume Setup screen. Select the desired mode along with the desired snapshot size and click Create volume now. The ioSafe R4 will proceed with a reboot to re-configure your volume to the desired specification. If no action is taken within 10 minutes, the system defaults to X-RAID and begins its initialization process.
5 Chapter Changing User Passwords There are two ways in which user passwords can be changed in the User security mode. The first way is for the admin user to change the passwords in the Accounts tab in the Security menu. The other and preferred way is to allow users to change their own passwords. This relieves the admin from this task and hopefully, encourages users to change their passwords on a more regular basis for enhanced security.
A Appendix RAID Levels Simplified RAID can be somewhat daunting; this appendix will help simplify RAID for you. RAID is an acronym for Redundant Array of Independent Disks. Basically, if properly configured, it can store data on multiple disks in a way that if one disk fails, the data can still be accessed from the surviving disk(s). A RAID level selects how data will be kept redundant, the most popular ones being levels 0, 1, and 5.
RAID Level “X” (X-RAID) RAID level “X”, or X-RAID, is similar to RAID level 5, is optimized for large sequential access for the best possible media streaming performance. The “X” also refers to its natural volume eXpandability. In X-RAID mode, with one disk, the volume is non-redundant and has the capacity of the single disk. By adding a 2nd disk, the capacity remains the same, but the data is now mirrored between the two disks. With redundancy, your data will not be lost in the event of a disk failure.
B Appendix Input Field Format Domain/Workgroup Name A valid domain or workgroup name must conform to the following restrictions: Name must consist only of characters a-z, A-Z, 0-9, and the symbols _ (underscore), – (dash), and . (period). Name must start with a letter. Name length must be 15 characters or less. Host A valid IP address or a host name.
Host Expression A valid host expression is either a valid host or the common IP expression form specifying a range of addresses in a network; for example: 192.168.2. 192.168.2.0/255.255.255.0 192.168.2.0/24 Share Name Name must consist only of characters a-z, A-Z, 0-9, and the symbols – (dash) and . (period). Name cannot be an existing user name. Name cannot end in –snap.
C Appendix Glossary AFP: AppleTalk Filing Protocol, is the standard way Mac OS 9 and earlier share files across the network. CIFS: Common Internet File System, a standard protocol that Windows users use to share files across the network. Mac OS X also has the capability to share files using CIFS. FTP: File Transfer Protocol, a common protocol adopted by many OS to enable remote file download and upload for public sharing.
