HP NAS 8000 Overview 1 What is NAS? Network-attached storage (NAS) is a storage solution attached to a network that is optimized for file sharing and serving. NAS provides a simple, reliable, and cost-effective way to add storage to networks. Because a NAS device is designed specifically for storage, it requires minimal setup and is easily maintained. NAS devices also have built-in redundancy features to protect against failure and downtime.
Product Overview The HP Surestore Network-Attached Storage (NAS) 8000 series offers several storage solutions that attach directly to your network and provide shared file storage for workgroups and departments. Hardware The NAS 8000 solution can include one or more of the following, sold separately or pre-installed in a rack: ■ A NAS server with a custom operating system. — Network interface cards (NICs).
Figure 1 NAS Racked System HP NAS 8000 Overview Other accessories sold separately are: ■ Uninterruptible power supply (UPS). ■ HP Surestore tape libraries.
Software The NAS 8000 server comes preloaded with: ■ A custom operating system optimized for file serving. A command line interface is available for advanced server management. ■ HP Command View NAS management software that runs in a web browser. This graphical user interface is the primary tool for managing the NAS 8000. Links to Command View SDM are provided for advanced array management.
HP NAS 8000 Overview Product Configurations The NAS 8000 is available in four configurations: ■ Direct-attached storage configuration ■ Direct-attached storage configuration with high availability ■ SAN configuration ■ SAN configuration with high availability Depending on the configuration of your NAS server, different options display in the Command View NAS web interface.
Figure 2 Direct Attached Configuration Direct-Attached Configuration with High Availability In direct-attached configurations with high availability, one or two VA7100 or VA7400 series disk arrays are attached to a cluster consisting of two NAS servers and a Quorum server that manages the high-availability services for the cluster. In addition: ■ A single HBA is pre-installed in each server. ■ A separate UPS is required for each NAS server. ■ Tape backup can be shared by both NAS servers.
Figure 3 Direct-Attached Configuration with High Availability HP NAS 8000 Overview HP NAS 8000 Overview 15
■ Multiple arrays may also be attached using FC switches.
SAN Configuration HP NAS 8000 Overview NAS 8000 solutions can also manage storage on HP VA7100, VA7400 series or XP model arrays connected to a SAN. LUNs must be created and assigned to the NAS 8000 using a product such as HP Surestore Secure Manager VA or Secure Manager XP.
SAN Configuration with High Availability A high-availability, clustered NAS 8000 system can also be configured to access VA7100, VA7400 series and XP model arrays attached via SAN.

20 HP NAS 8000 Overview
NAS 8000 Concepts 2 Understanding Physical and Logical Storage The storage space on your HP NAS 8000 is made up of physical storage and logical storage for a direct-attached and SAN configuration. Before you begin planning your storage, you need to understand the following concepts. Physical storage refers to the hardware used for data storage. The physical storage components of the HP NAS 8000 are the disk drives.
Figure 1 Physical and Logical Storage Physical Storage Disk Drives The HP NAS 8000 supports the following storage devices either directly attached to the NAS 8000 or on a SAN: ■ Virtual Array (VA) 7100 is a disk storage system that holds from 4 to 15 disk drives. The array has scalable capacities from 72 GB to over 1 Terabyte depending upon the size and number of disk drives. The capacity of the disk drives can be mixed.
Logical Storage The HP NAS 8000 lets you set up your storage into these logical divisions: Logical Unit Number A logical unit number (LUN) is a logical aggregation of the space on one or more physical drives. The HP NAS 8000 supports a maximum of 127 LUNs. Volume Groups File Volumes A volume group is divided into one or more file volumes. File volumes are the basic unit of logical storage for a file system on the HP NAS 8000. File volumes can be further subdivided into individual directories.
Understanding High Availability Note This section applies only if you have purchased a highavailability NAS solution. High availability characterizes a system that is designed to avoid the loss of service by reducing or managing failures and minimizing downtime. High availability implies a service level in which both planned and unplanned downtime is minimized.
Figure 2 Cluster Components NAS 8000 Concepts Failover Models Failover is a backup operational mode in which the functions of one NAS server are assumed by the other NAS server when a NAS server becomes unavailable through failure or scheduled down time.
Active/Active Failover Model In the active/active failover model, both NAS servers provide simultaneous access to storage. Each NAS server maintains separate file systems, CIFS shares, and NFS exports. The NAS servers do not provide shared access to the same volumes and file systems simultaneously. Each NAS server functions as a separate file server.
Failover Packages Think of a package as a group of one or more volume groups (with their file systems and shares/exports) that will fail over as a single unit. To fail over a package manually, you need to: ■ Stop the existing package (in the case of a service, network, or resource failure). ■ Start the new instance of the package on a different node. You can manage failover packages on the Storage tab of the Command View NAS web interface.
High-Availability Options in the Command View NAS Web Interface You can manage high-availability options on the following tabs of the Command View NAS web interface: ■ Configuration tab: Start or stop clustering services; manage node settings for your cluster; name your cluster; enter a name for the Quorum server; and set up timeouts and intervals for the cluster. ■ Storage tab: Add, edit, delete, start, and stop failover packages. You can also manually fail over or fail back a package.
About HP NAS Server Security Two basic ways to ensure the security of the NAS server are: ■ Control access to the device ■ Set an administrative password to ensure that only authorized users gain access to key administrative functions HP NAS Server Security in a UNIX-only Environment UNIX uses a reasonably simple approach to data access security. Each workstation performs user authentication locally. Each user is associated with a 16-bit integer (user ID or UID).
NAS server then maintains the same UID and GID numbers that your UNIX users are currently assigned in a heterogeneous environment. Note Whether you disable or enable the use of a NIS server, you are in no way affecting the security of a homogenous UNIX environment. An additional form of security called host access is available in the UNIX environment and controls which client machines are allowed access to the NAS server, regardless of the user.
Share-Level Security With share-level security, the server explicitly asks for permission (password) every time a user connects to a share on the NAS server. Thus, any user on the network who knows the name of the NAS server, the name of the resource (or file), and the password has access to the resource. When you are using share-level security, you can assign shares a read-only password and/or a read-write password. User Level (Domain) Security The NAS server supports the NT Master Domain model.
Permissions You can assign the following permissions to an NT resource: ■ Read ■ Delete ■ Write ■ Execute ■ Change Permissions ■ Take Ownership Additionally, you can group these permissions into standard permissions that consist of one or more previous permissions.
Accessing Files Created by UNIX Clients When an NT user accesses a UNIX file, the UNIX file permissions are translated into an ACL that then determines the permissions to grant. Recall from HP NAS Server Security in a UNIX-only Environment that permissions are granted to three distinct groups: ■ user ■ group ■ other This table shows the mapping that takes place between the permissions.
Accessing Files Created by NT Clients Directly mapping NT permissions to UNIX permissions causes some difficulty because NT permissions have a greater level of complexity. UNIX users are unable to use either the chmod or chown commands to modify the permissions or owners of NT files. The table below shows which UNIX-to-NT file permissions are mapped.
Getting Started 3 Using the Command View NAS Web Interface The NAS server and storage array are managed via a web browser. You will perform most administrative tasks with this interface. The Command View NAS requires the Sun Microsystems Java™ Plug-in 1.3.1_01, Standard Edition. Supported browsers include Internet Explorer 5.5 and Netscape 4.77. For more information on supported browser versions for Windows, Solaris, and Linux platforms, see http://java.sun.com/products/plugin/.
Figure 1 Note Identity Page If you have trouble connecting, try enabling the browser's option to bypass the proxy server for local addresses.

Using Online Help You can access the NAS server’s online help from the Command View NAS web interface. Click or the Help button in the dialog box windows to access online help. The Command View NAS web interface then opens a toplevel help menu. This context-sensitive online help is preloaded on your NAS server. Help is organized into main-level and sub-level topics.
Task Overview Prerequisites During setup, your NAS 8000 was installed and configured by an HP storage specialist who performed these tasks: 1 Planned your network and storage settings.. You should have done this with your HP installation specialist prior to receiving the product. See your HP Surestore NAS 8000 Solution Integration Manual (SIM) Binder for your Network and Storage Planning Guide and “Understanding Physical and Logical Storage” on page 21 in this user's guide for more information.
■ Monitor your system by viewing settings on the Status tab (see Chapter 6, Monitoring the System). You'll need to check the status of your system if there is a problem (your system may be set up to automatically notify you of problems). ■ Determine a virus and backup strategy (see Chapter 7, Enabling Virus and Backup Software). The HP NAS 8000 provides a backup agent, disaster recovery, virus protection, and snapshots functionality to protect your data.
42 Getting Started
Configuring Your System and Network 4 During installation, an HP storage specialist configured your system as part of setup using the web-based Configuration Wizard in the NAS 8000 web interface. (See the HP Surestore NAS 8000 Installation Guide in your SIM Binder for information.) Now you may want to make changes to your settings. You can do so through the Configuration tab, which contains the following configurable parameters:. ■ System Properties. These are informational settings.
Using the Configuration Wizard The Configuration Wizard automatically appears the first time you connect to the NAS server using a web browser. After that, you can access the wizard to perform guided configuration tasks as follows: ■ Open the Command View NAS web interface by typing the IP address in the address or location field of a web browser (you configured this address during installation). The Wizard (shown below) guides you through configuration.
The Wizard lets you: ■ Define your system name ■ Set the date and time ■ Enter your contact information ■ Set UPS monitoring ■ Specify a password ■ View the Command View NAS access list ■ Define your TCP/IP addresses ■ Enter DNS settings ■ Enter your node settings, cluster name, Quorum server name, and timeouts and intervals if you have a high-availability NAS solution ■ Set up your Windows (WINS properties and security settings) and UNIX (NIS and NFS settings) environments ■ Set SNMP and email (SMTP) a
Identifying your NAS Server The first time you access Command View NAS, the Configuration Wizard appears to guide you through configuration.
Shutting Down and Restarting Direct-Attached and SAN Configuration The Shutdown/Restart option applies only to the NAS server. If you need to shut down a direct-attached storage array, shut down the NAS server first. Shut down the NAS server if you: ■ Move the device to a new location ■ Anticipate a power outage in your building and you do not have an uninterruptible power supply for the device Restart the NAS server if you install a new version of the Command View NAS web interface.
High-Availability Configuration If you have a high-availability NAS server, you have several shutdown options: ■ Stop the server and do not fail over packages. You can manually stop each package, then stop the server, or you can stop the server and cause the packages to stop automatically. Once the server is stopped, it is no longer active in the cluster and is not serving any file systems, so you can safely stop it by following steps 1-4 in “Direct-Attached and SAN Configuration” on page 47.
Configuring System Security Editing the Command View NAS Access List The Command View NAS access list allows you to define the machines that may access the Command View NAS web interface. If a specific machine's hostname or IP address is not listed, that machine cannot access the Command View NAS. To set up the Command View NAS access list: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to System Security. 3 Select Actions > Edit GUI Access List.
4 In the Current Password field: — If you are assigning a password for the first time or if you removed your password, leave this field blank. — If you are changing or removing the administrative password, enter the current password in this field. 5 In the New Password field: — If you are assigning a password for the first time or changing your password, enter a password in this field.
Configuring System Settings Defining the System Name Note If you have a high-availability NAS server, you must stop clustering services to edit the information. The system name uniquely identifies your NAS server on your network. It is a text string that contains as many as 15 characters drawn from the alphabet (A-Z), digits (0-9), and minus sign (-). No distinction is made between upper and lower case. However, the name must begin with a letter and the last character must not be a minus sign.
Setting the Date and Time The NAS server uses the information on this screen to keep track of the date and time for operations such as time stamps for file generation and modification. Failure to set the proper date and time may lead to confusing behavior or misleading time stamping of files and log messages. To set the system date and time: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to System Properties. 3 Click Actions > Edit System Time.
— Description of the NAS server's physical location in the *Location field. — Description of the NAS server's specific position on your hardware rack in the Rack ID field — Device's specific location of the rack at your location in the Rack Position field — Number that your company might use to identify and track the NAS server in the *Asset Number field 5 Click OK. *Information appears on the Identity screen. Note Blank fields do not affect the functionality of the device.
Configuring TCP/IP Settings Defining IP Addresses Note If you have a high-availability NAS server, you must stop the clustering services to edit the information. The NAS server has one Network Interface Card (NIC) port on the motherboard and supports two additional slots for NICs. These cards can be either dual-port 10/100 cards or single-port gigabit cards. This support gives the system up to five NIC ports (one on the motherboard and the capacity for a maximum of two dual-port 10/100 NICs).
If you have DHCP enabled, NIC configuration occurs automatically. Depending on your configuration, the DHCP server provides any or all of the following parameters: IP Address, Subnet Mask, Gateway Address, Broadcast Address, and DNS Domain Name. To edit the IP configuration for a NIC port: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to TCP/IP > IP Addresses.
Defining the Command View Management Port The Command View Management Port lets you define a secure port through which the NAS server and the Command View NAS web interface can communicate. The port is defined by port designation such as eth0 and eth1; it is not defined by IP address. eth0 is always the on-board port and is the default management port.
— setNetworkCardSubnetMask ethX X.X.X.X (first parameter is the port designation and second parameter is the subnet mask). — setNetworkCardGatewayAddress ethX X.X.X.X (first parameter is the port designation and second parameter is the gateway address). ■ Enslave the first port to the bond. The bond will then assume the IP configuration of the first port enslaved. — bondEnslaveNetworkCard ethX bondY (first parameter is the port being enslaved into the bond that is designated by the second parameter).
Setting the Domain Name Service (DNS) Domain Name Servers convert system names that people can remember (such as nas8000.fc.hp.com) to IP addresses (such as 123.45.67.89) that are used by packet-routing software. To enter the DNS information: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to TCP/IP > DNS. 3 Select Actions > Edit DNS Values. 4 If required, enter the DNS Domain Name. The NAS server can belong to only one domain.
Configuring High-Availability Settings Cluster Configuration Overview Note This section applies only if you have purchased a highavailability NAS solution. You must configure your cluster. Follow these steps in order. Task... Details... 1. Preliminary node configuration See the HP NAS 8000 High-Availability Server Installation Guide in your SIM Binder. 2. Define the cluster After you complete the minimum network configuration on both of the cluster nodes (servers), you can define the cluster.
Task... Details... 4. Configure the node You can now complete the balance of the node configuration on each node. The cluster can be either up or down. A defined cluster allows subsequent node configuration to be synchronized between the nodes (assuming that they are available on the network). 5. Configure the storage 1 Create volume groups. (See “Creating a Volume Group” on page 82.) 2 Assign volume groups to packages and start packages to activate volume groups.
Entering Node Settings Note This section applies only if you have purchased a highavailability NAS solution. Before you proceed, you must stop the clustering services to edit the information. You initially enter your node settings in the Configuration Wizard. The node settings let you configure the two nodes (servers) in your cluster. Each server has one ore more network interface cards that can be selected to provide cluster heartbeats.
Defining the Cluster Name Note This section applies only if you have purchased a highavailability NAS solution. Before you proceed, you must stop the clustering services to edit the information. The cluster name identifies your cluster on your network. It is a text string that is limited to 40 characters and cannot contain spaces, forward slash (/), backslashes (\), or asterisks (*). To name a cluster: 1 In the Command View NAS web interface, click the Configuration tab.
4 In the Quorum Server field, type the hostname for the Quorum server on your network. 5 Click OK. Setting Timeouts and Intervals Note This section applies only if you have purchased a highavailability NAS solution. Before you proceed, you must stop the clustering services to edit the information. The values you set on this screen let you determine the rate at which problems on the NAS server are detected. You can set timeouts and intervals for the Quorum server, heartbeat, and network-failure detection.
— Node Timeout: Timeout value for a heartbeat between nodes. If a heartbeat is not detected for this specified amount of time, the node awaiting/monitoring the heartbeat will determine that the node is unavailable and will commence cluster reformation and package failover. 5 Click OK. Starting and Stopping Clustering Services Note This section applies only if you have purchased a highavailability NAS solution. Once a cluster configuration exists, you can manually start clustering services.
To start or stop clustering services: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to High Availability, then select Cluster Services. 3 Select: — Actions > Start Clustering Services. You will not be able to select this item if the clustering services have already been started. — Actions > Stop Clustering Services. You will not be able to select this item if the clustering services have already been stopped.
Configuring Networking Settings Windows Settings Specifying WINS Properties Similar to DNS, the Windows Internet Naming Service (WINS) is the Windows NT server method for associating a computer's hostname with its address. To specify the WINS properties: 1 In the Command View NAS web interface, click the Configuration tab, navigate down the tree to Networking Settings > Windows. 2 Select Actions > Edit WINS Properties. 3 Enter a WINS Server IP Address.
4 Select either: — Share Level Security: Specify the Workgroup to which the NAS server belongs. — User Level Security (see your system administrator for the following Windows security information): a Enter the Domain name. The system administrator must have already created an account for the NAS server in the domain you choose to join. This is on the planning worksheet in your SIM binder. b Enter the name or IP address for the Primary Domain Controller (PDC).
UNIX Settings Specifying NIS Properties The NAS server supports Network Information System (NIS). NIS maintains a central database of names and locations of resources on a network. NIS was formerly known as Yellow Pages. To enable or disable NIS: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to Networking Settings > UNIX. 3 Select Actions > Edit NIS Properties. 4 Check Disable NIS or Enable NIS (Disable NIS is the default).
Specifying NFS Properties Network File System (NFS) settings are optional. NFS is a client/server application that lets a user view and optionally store and update files on a remote computer as if the files were on the user's own computer. 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to Networking Settings > UNIX. 3 Select Actions > Edit NFS Properties. 4 You can change the number of Network File System Daemon (NFSD) processes.
Configuring Alert Settings Defining SNMP Alerts If you are using a network management product such as HP OpenView, CA Unicenter, or Tivoli Network Node Manager, you can define the names of management workstations to receive notification in case of a failure. For more information about these products, see the HP Surestore Enterprise Integrations Installation and User Guide at http://www.hp.com/support/emsp. Note The information on this screen is optional.
Defining Email Alerts (SMTP) The NAS server lets you automatically notify individuals via email if there is a hardware failure or a critical system alert. Note The information on this screen is optional. Blank fields do not affect the functionality of the device. In the event of a hardware failure or system alert, messages are sent through the network management tool or they are logged in the system log.
Setting Up the Remote System Log You can redirect a copy of the system log to a specified server. This redirection lets you manage a central location for the event log instead of working with different interfaces or systems. Note To receive the log messages from the NAS server, you must enable remote system-log capabilities on your UNIX system. First, add the -r option as part of the syslogd daemon's startup parameter. Then, restart the syslog service.
Configuring User and Group Mapping Understanding User and Group Mapping This screen lets you map Windows users/groups, who use the Server Message Block Protocol/Common Internet File System protocol (SMB/CIFS), to UNIX users/groups, who use the Network File System protocol (NFS): ■ SMB/CIFS, the Windows protocol for sharing files, lets client applications read and write to files. CIFS is a standard protocol that lets programs request files and services on remote computers over the internet.
To set up user or group mapping: 1 In the Command View NAS web interface, click the Configuration tab. 2 Navigate down the tree to Mapping, then select User Mapping or Group Mapping. A table displays the current mappings of Windows to UNIX users/groups. 3 Select Actions > Add User Mapping Entries or Add Group Mapping Entries. 4 In the Windows user or group domain section, select a domain from the drop-down list, then select a user or group from the list.
Importing and Exporting Users or Groups In addition to setting up user/group mapping, you can export a list of Windows and UNIX users/groups, which might help you map users/groups. Also, you can import or export a user/group map file. Importing a user/ group map lets an unlimited number of mappings occur simultaneously. Exporting a user/group map lets you save the map for later use or for disaster recovery.
Configuring UPS Connections If you connected an optional UPS to your NAS server during installation, the NAS server attempts to communicate with the UPS through a serial connection. To set up and monitor a UPS connection for your NAS server: 1 The APC UPS has only one serial port. The NAS server, however, has two ports. Connect the UPS serial port to the COM1 port on the back of the NAS server. See the HP Surestore NAS 8000 Installation Guide for more detailed information.
Managing Your Storage 5 To set up your storage, you need to implement your plan. You do so in the Storage tab. Note You must completely configure your NAS server before you attempt to set up your storage. For more information, refer to the HP Surestore NAS 8000 Installation Guide or access the Configuration Wizard in the Configuration tab. In the Storage tab, you must: ■ Create Logical Unit Numbers (LUNs).
Managing Arrays and LUNs Viewing the Storage Array Summary The Storage Array Summary page displays a table that lists the storage array attached to the NAS server and information about its storage configuration. To examine and manage the storage you have available: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to Storage Array Summary.
■ Scan for a new storage ■ Rename an array ■ Launch the array user interface for advanced array management ■ Create a new LUN ■ Delete the selected LUN Note If you have a SAN, you can only scan for new storage. The other topics are grayed out. You can also refresh the items in your display by selecting Actions > Refresh. Scanning for New Storage If you attach a new array, you must scan for the new array and the array's LUNs to make them accessible.
Using Advanced Array Management Note If you have a SAN, disregard this topic. Advanced Array Management lets you do the following for the array(s) attached to the NAS server: ■ View data resiliency ■ Modify RAID levels (the default is AutoRAID) ■ Enable or disable active spare mode ■ Automatically include and format new drives If you select this option, the Command View SDM web interface is launched. See “Command View SDM Limitations” on page 213 for more information.
4 The Create New LUN dialog box appears. If you have a: — VA7400 series array, select a redundancy group from the drop-down list, select a LUN number from the drop-down list, and enter the LUN size. 5 Click OK. Once you have created a LUN, you are ready to create a volume group. Deleting a LUN Note If you have a SAN, disregard this topic because you can not delete LUNs. To delete a LUN: 1 In the Command View NAS web interface, click the Storage tab.
Managing Volume Groups Viewing Volume Groups A volume group is made up of one or more LUNs. To view the volume group: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree and select Volume Groups.
6 Click OK to create the new volume group. Note If you have a high-availability NAS solution, you must assign the volume group to a package before you can perform any further storage configuration. The only way to activate a volume group is to start the package to which you have assigned the volume group.
Deleting a Volume Group Before you delete a volume group, you must first delete any file volumes or snapshots associated with the volume group. Note If you have a high-availability NAS solution, before you delete the volume group, you must first stop and delete the package that contains the volume group. To delete a volume group: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree and select Volume Groups.
Managing Your Storage Managing Failover Packages Viewing Failover Packages Note This section applies only if you have purchased a highavailability NAS solution. All storage is controlled by packages. Packages are the smallest units of failover in the cluster. In other words, if a package resource (storage or network) fails, the package will be failed over to another node. Each package and its associated resources are monitored independently.
Column Description Reboot on Failure Enabled or disabled. If Reboot on Failure is enabled and a failure occurs, the server automatically reboots. Primary Node Hostname of the NAS server that is designated as the owner of the package. Under normal circumstances, the primary node (server) should start the package by default. This name is selected from the list of cluster members or nodes specified in the cluster configuration. Volume Groups Volume groups that the package maintains.
8 Select a Primary Node that you want to start the package from the dropdown list. 9 From the Available Volume Groups list, select the volume group(s) you want to include in the package, then click Select. 10 Enter a Virtual IP Address (an IP address used to access the storage associated with the package) and enter the Subnet. Click Add. 11 Click OK. To activate the package, you must start it. See “Starting a Package” on page 88 for information.
Deleting a Package Note This section applies only if you have purchased a highavailability NAS solution. Before you proceed, you must stop the package to edit the information. Deleting a package does not delete the volumes and shares/exports within the package. However, once the package is deleted, the volumes within the deleted package will not be accessible to client systems until you add them to another package. To delete a package: 1 In the Command View NAS web interface, click the Storage tab.
Stopping a Package This section applies only if you have purchased a highavailability NAS solution. The file system services, NFS, and CIFS are temporarily stopped; the volumes within the package are unmounted; and NFS and CIFS are restarted. Once the package has been stopped, it can be restarted on any active server in the cluster. After a package is stopped, the volumes within the package are no longer available to client systems until the package is restarted.
A package failover involves both stopping the existing package on one node and starting the new instance of the package on the other node. You would manually fail over a package when: ■ You need to take the primary server down for moving, cleaning, or service. ■ You want to transfer a package to the secondary server. To fail over a package: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree and select Failover Packages.
Viewing File Volume Information File volumes are the basic unit of logical storage for a file system on the NAS server. You create file volumes by allocating space in a volume group. Therefore, before you can create a file volume, you must create a volume group. After you have created file volumes, you can create directories under the new file volumes to organize your data.
Creating a New File Volume File volumes are the basic unit of storage for a file system on the NAS server. In order to create file volumes, you must already have created one or more volume groups. To create a new file volume: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to File Volumes, then select File Volumes Summary. 3 Select Actions > Create New File Volume. 4 Select a volume group from the pull-down menu. 5 Enter a new File Volume Name.
Editing a File Volume Managing Your Storage The Edit File Volume dialog box lets you: ■ Rename the file volume ■ Extend the size of an existing file volume ■ Enable/disable quotas ■ Change the trap threshold You cannot change the volume group that the file volume is a part of. An important aspect of managing file volumes is the concept of resizing file volumes. If a file volume becomes full of data, you can extend the file volume, thus alleviating the lack of space on the file volume.
Deleting a File Volume When you delete a file volume, the volume group reclaims the space it used. Caution Deleting a file volume destroys all the data on that volume. This procedure cannot be reversed. Therefore, remove all crucial data before you delete the volume. Before you proceed, make sure no one is accessing the file volume and delete all snapshots associated with the file volume. To delete a file volume: 1 In the Command View NAS web interface, click the Storage tab.
Managing Your Storage Managing Shares and Exports Viewing Shares and Exports Before network users can access the NAS server, you must give them permission. This is a security concern. Each platform grants permission differently: ■ Windows: Shares are permissions that let you control Microsoft Windows users' access to data. You can create shares for any directory within a file volume, including the root.
Creating or Editing an SMB Share You can control access to the NAS server data by creating SMB shares for Windows clients. A host allow list lets you limit which client machines are allowed access to the NAS server, regardless of the user. To create or edit an SMB share: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to File Volumes, then select Shares/Exports. 3 Select the file volume where you want to create the share by clicking the row.
Creating or Editing an NFS Export To create or edit an NFS export: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to File Volumes, then select Shares/Exports. 3 Select the file volume where you want to create the share/export by clicking the row. 4 Select Actions > Create New NFS Export (if you want to edit an export, select Edit Selected NFS Export). 5 Enter the Mount Name. 6 Select either Read Only or Read/Write.
Verifying that the HP NAS Server Is Accessible to Users Windows To assign (map) a drive letter to a shared network resource, select My Network Places or Network Neighborhood (depending on your operating system) to map a drive to the shared resources (SMB shares) managed by the NAS server. UNIX Use the mount command to mount an exported network resource: mount machine:/nfs/ where was the name defined by the administrator when the export was created.
Renaming a Directory Managing Your Storage To rename a directory: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to File Volumes, then select Shares/Exports. 3 Navigate through the directory tree that appears in the browser and highlight the directory you want to rename. 4 Select Actions > Rename Selected Directory. 5 Enter a new name and click OK. Deleting a Directory You can delete directories to free up disk space or to remove unwanted data on the NAS server.
Replicating Data with Snapshots Using Snapshots A snapshot is a read-only picture of a file volume at a specific point in time. When you create a file volume, the snapshot of that file volume is of zero length. However, as you modify the file volume, the snapshot tracks changes between the original file volume and the modified file volume.
Creating a Snapshot To create a new snapshot: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to Snapshots, then select Snapshot Summary. 3 Select Actions > Create New Snapshot. 4 Select the file volume you want to take a snapshot of from the File Volume drop-down list. 5 Enter a Snapshot Name. 6 Enter the maximum size for the snapshot volume in the Snapshot Capacity field. A snapshot cannot exceed the file volume size.
Editing a Snapshot To edit a snapshot: 1 In the Command View NAS web interface, click the Storage tab. 2 Navigate down the tree to Snapshots, then select Snapshot Summary. 3 Select the snapshot you want to rename. 4 Select Actions > Edit Selected Snapshot. 5 You can: — Enter a new Snapshot Name. — Enter the size you want the snapshot to become being careful to remain within the limits stated. — Change the snapshot capacity policy. — Change the expiration date. 6 Click OK.
Scheduling a Snapshot ■ File volume name of the snapshot ■ Snapshot name ■ Size allocated to the snapshot ■ Auto grow enabled ■ SNMP trap percentage ■ Frequency of re-occurrence of the snapshot ■ Expiration date of the snapshot When you schedule a snapshot, make sure your NAS server will have sufficient space to accommodate the snapshot. (The system does not preallocate space and assumes that space will be available at the time the snapshot is scheduled to take place.
snapshot volume takes up a lot of valuable storage space. You can always resize a snapshot at a later time. — Send Notification at and select a percentage from the drop-down list to send an SNMP alert when the space used on a snapshot volume reaches a certain percentage. When data is written to the new snapshot, the available space in the snapshot volume decreases. Note: This percentage is used in conjunction with the settings you entered on the SNMP alert, email, and Syslog configuration pages.
Understanding Quotas Quotas allow you to restrict the space usage on the NAS server for both users and groups. A user or group who goes beyond the specified space usage can not access the system. Each user can have one quota on a file volume. Quotas are set on a per file volume basis. You can have a quota larger than the available space on the file volume. Enabling or Disabling Quotas To enable or disable a quota: 1 In the Command View NAS web interface, click the Storage tab.

F Glossary A Access Control List (ACL) Active spare Agent Aggregation A list associated with a file that contains information about which users or groups have permission to access or modify the file. A previously installed physical drive used as a backup in case an assigned drive fails. The active spare automatically takes over the duties of the failed drive. A program that performs a background task for a user and reports to the user when the task is done or some expected event has taken place.
C CIFS (Common Internet File System) Cluster Collision A standard way of sharing resources over an IP Network. This standard supercedes SMB. A group of servers that act like a single system. The result of two devices transmitting signals at the same time on the same channel, usually resulting in a garbled transmission.
Domain (TCP/IP) Domain Name Service (DNS) Server Dual In-line Memory Module (DIMM) An alphanumeric representation of an association of computers. (For example, hp.com. com is a top level domain and hp is a second level domain. A server that translates domain names (such as hp.com) into IP addresses (such as 15.12.255.67). If you have multiple DNS servers on your network, and one DNS server cannot translate a domain name, it asks another one, and so on, until the IP address is found.
networking. The data transfer rate is one gigabit per second (1 Gbps) or more. Group Identification (GID) Group quota A number in the UNIX environment that identifies a group of individuals or services to a computer system. Lets you restrict the space usage on the NAS server for groups. H Heartbeat A periodic signal generated by the server to indicate that it is still running.
L LAN (Local Area Network) Logical drive LUN (Logical Unit Number) A group of computers and other devices, within a specific location (typically within a building or floor of a building), connected by a communications link that enables any device to interact with any other on the network. LANs commonly include microcomputers and shared resources such as laser printers and storage devices. A logical grouping of one or more physical drives on a system, commonly referred to as a RAID set.
With NFS, computers connected to a network operate as clients while accessing remote files, and as servers while providing remote users access to local shared files. The NFS standards are publicly available and widely used. P Package control log A log file is maintained for each package in a cluster. The software and the package monitor log messages that are specific to the package log files. (This feature is available only on high-availability NAS devices.
Remote system log A file located on a UNIX machine containing statistics and error messages. See also syslog. S SAN (Storage Area Network) SCSI (Small Computer System Interface) Security Account Manager (SAM) database Network that connects storage devices and computer systems. A SCSI interface is used to connect microcomputers to SCSI peripheral devices, such as many hard disks and printers, and to other computers and local area networks. A database used to authenticate users.
Snapshot A read-only copy of a file volume that contains an image of the volume as it appeared at the point in time when the copy was taken. Subnet Mask A 32-bit numeric mask that blocks out all but the necessary information. This allows the IP address to be broken into a component that identifies the subnet on which the device resides and the ID of the device itself.
computer is not interrupted because of a blackout. UPS protects the computer against potentially damaging events such as power surges and brown-outs. User authentication See Authentication. User Identification (UID) A unique number in the UNIX environment that identifies an individual to a computer system.
