1 Installing and configuring the storage system Setup overview The HP StorageWorks X1000 G2 Network Storage System comes preinstalled with the Microsoft Windows® Storage Server™ 2008 R2 Standard Edition x64 operating system with Microsoft iSCSI Software Target and HP Automated Storage Manager (HP ASM) included.
The type of access you select is determined by whether or not the network has a Dynamic Host Configuration Protocol (DHCP) server. If the network has a DHCP server, you can install the storage system through the direct attachment or remote management methods. If your network does not have a DHCP server, you must access the storage system through the direct attachment method. The direct attachment method requires a display, keyboard, and mouse. These components are not provided with the storage system.
Connect to the storage system Use either the direct connect or remote management method to connect to the storage system. IMPORTANT: Only the direct attach and remote management access methods can be used to install the storage system. After the storage system installation process is complete and the system's IP address has been assigned, you can then additionally use the remote browser and remote desktop methods to access the storage system.
Power on the server and log on Power on the server after installing the hardware and connecting the cables. Powering on the server for the first time initiates the storage system installation process. 1. Power on the system by pushing the power button on the front panel. If using iLO, click Momentary Press on the Power Management page to power on the server, then click Launch on the Status Summary page to open the iLO Integrated Remote Console and complete the installation process.
To check the activation status of Windows, open Control Panel (Start > Control Panel) and then double-click System. If your copy of Windows has been activated, the status under Windows activation will read Windows is activated. If your copy of Windows has not been activated, you must manually activate it within three days of the initial storage system installation. To manually activate your copy of Windows: 1. If needed, change your locale settings (Control Panel > Regional and Language Options). 2.
controller (NIC) teams in a Windows-based operating system. These teams provide options for increasing fault tolerance and throughput. • Adjusting logging for system, application, and security events. • Installing third-party software applications—For example, these might include an antivirus application that you install. • Registering the server — To register the server, refer to the HP Registration website (http://register.hp.com).
IMPORTANT: If you are using the remote browser method to access the storage system, always close the remote session before closing your Internet browser. Closing the Internet browser does not close the remote session. Failure to close your remote session impacts the limited number of remote sessions allowed on the storage system at any given time.
As of the SWX image version 1.2, the DON'T ERASE volume that was created on earlier versions of HP StorageWorks Network Storage System models is no longer used. IMPORTANT: The first two logical drives are configured for the storage system operating system. The Operating System volume default factory settings can be customized after the operating system is up and running.

3 Administration tools HP StorageWorks X1000 G2 Network Storage Systems include several administration tools as well as HP StorageWorks Automated Storage Manager (ASM) to simplify storage system management tasks. HP StorageWorks Automated Storage Manager After installing and setting up your storage system, you can begin managing your storage using the HP Automated Storage Manager (HP ASM). HP ASM comes preinstalled on all HP X1000 G2 Network Storage Systems.
• Remote Desktop Connection • Remote Web Administration • Windows Server Remote Administration Applet For more information, see the Windows Storage Server 2008 R2 Help. Share and Storage Management With the Share and Storage Management snap-in provided in this release, you can more easily set up and manage shared folders and storage. Share and Storage Management provides the following: • MMC-based management of shared folders and storage.
folder. The duplicate is then replaced by a link (a reparse point) to the central copy. The link file contains information about the original file, such as its current location, size, and attributes. The Single Instance Storage Filter runs in kernel mode. The Single Instance Storage Filter service cannot be stopped. If this service is disabled, the linked files are not accessible. If the central folder is deleted, the linked files can become permanently inaccessible.
Administrators can install printers remotely by using the automatic detection feature, which finds and installs printers on the local subnet to the local print server. Administrators can log on remotely to a server at a branch location, and then install printers remotely. For more information, see the Windows Storage Server 2008 R2 Help.
Phase 1 scripts Phase 1 scripts are located in the c:\hpnas\components\postinstaller\adlds folder. You enable AD LDS NFS mapping by running factory-setup-adlds.cmd. The command is run without any arguments. The script installs two Roles and one Instance: • Active Directory Lightweight Directory Services (AD LDS) Role • An AD LDS Instance named NFSInstance.
having the same ID. This mapping is what allows directories and files to be accessed from either the Windows NFS server or the UNIX NFS client using the same User ID and Group ID. The nfs-adlds-config.js script will also add Windows users to the appropriate Windows groups for the newly created user and group accounts. It does this by examining the relationships between users and groups in the password and group files that were given as inputs to the script.
Figure 23 AD LDS script execution help screen . As a best practice, specify all of the above parameters so that Windows accounts and NFS mappings are created; however, you can provide finer control as follows. If you omit the /ldf option, the script creates Windows accounts but not NFS mappings. Likewise, omitting the /usercmd option creates NFS mappings but not Windows accounts. The /execute option controls whether Windows accounts and NFS mappings are actually made to the system.
The newly-created NFS mappings are stored as Active Directory objects and can be verified as follows: 1. Click Start > Administrative Tools > ADSI Edit. 2. On the Action menu, select Connect to.... 3. In the Connection Settings dialog box, under Computer, select the radio button labeled Select or type a domain or server: (Server|Domain[:port]). 4. In the Select or type a domain or server: (Server|Domain[:port]) field, type localhost:389 and then click OK.
Figure 25 NFS-mapped users and groups in ADSI Edit . Because the imported users and groups are now Windows users and groups as well as UNIX users and groups, you can use NFS sharing so that volumes, folders and files are visible in both the Windows file system and the UNIX file system. When you set ownership or permissions in the Windows file system, the proper ownership and permissions are set on the UNIX side.
Step 1 If you have not already run the Phase 1 script factory-setup-adlds.cmd, do so now. The script is located in the c:\hpnas\components\postinstaller\adlds folder.
Figure 26 NFS Advanced Sharing dialog box . Click the Permissions button. In the Type of access list, select Read-Write. Check the Allow root access check box. Figure 27 NFS Share Permissions dialog box . Click OK twice to return to the NfsTest Properties dialog box.
Step 5 In the NfsTest Properties dialog box, select the Security tab. This tab shows the current security settings for the folder. The following steps will add permissions for Everyone to have access to the NfsTest folder. To do this, click Edit… and then click Add…. Under Group or user names: type Everyone and then click OK. In the Permissions for NfsTest dialog box, check the Allow check box for Full control under Permissions for Everyone. Figure 28 Permissions for NfsTest dialog box .
check the Owner check box and then click OK. Note that root is part of the owner name. This verifies that NFS mapping is functional for the root user. Step 8 On the Windows system as Administrator, create a file file.txt in C:\NfsTest. Windows Explorer now displays its properties: On the UNIX system, issue a listing of the /mnt/nfstest directory. This listing displays the following information. Note that file permissions on your system may be different than those shown here.
Step 10 On the UNIX system, issue a listing of the /mnt/nfstest directory. Because you changed the owner of file.txt on the Windows system to user1, the owner of the file on the UNIX side is also user1. Because user1 is in the allusers group on the Windows system, the group ownership of file.txt is allusers on the UNIX side. If the group for file.txt is listed as nfsnobody, you must enable Microsoft hotfix 2222746 and restart the storage system as described in “Shared access example” on page 49.
Figure 31 Replace owner on subcontainers and objects . Click OK four times to dismiss the Properties dialog box. Return to the Properties dialog box, select the Security tab, and then click Edit. Select Everyone in the list of groups and user names and then click Remove. Next, click Add and add user1. Select full control for its permissions. Figure 32 Permissions for NfsTest dialog box . Click OK twice to dismiss the NfsTest Permissionsand Properties dialog boxes.

4 Storage management overview This chapter provides an overview of some of the components that make up the storage structure of the storage system. Storage management elements Storage is divided into four major divisions: • Physical storage elements • Logical storage elements • File system elements • File sharing elements Each of these elements is composed of the previous level's elements. Storage management example Figure 33 depicts many of the storage elements that one would find on a storage device.
Figure 33 Storage management process example . Physical storage elements The lowest level of storage management occurs at the physical drive level. Minimally, choosing the best disk carving strategy includes the following policies: • Analyze current corporate and departmental structure. • Analyze the current file server structure and environment. • Plan properly to ensure the best configuration and use of storage. • Determine the desired priority of fault tolerance, performance, and storage capacity.
• Include the appropriate number of physical drives in the arrays to create logical storage elements of desired sizes. Arrays See Figure 34. With an array controller installed in the system, the capacity of several physical drives (P1–P3) can be logically combined into one or more logical units (L1) called arrays. When this is done, the read/write heads of all the constituent physical drives are active simultaneously, dramatically reducing the overall time required for data transfer.
Fault tolerance Drive failure, although rare, is potentially catastrophic. For example, using simple striping as shown in Figure 35, failure of any hard drive leads to failure of all logical drives in the same array, and hence to data loss. To protect against data loss from hard drive failure, storage systems should be configured with fault tolerance. HP recommends adhering to RAID 5 configurations.
It is important to note that a LUN may span all physical drives within a storage controller subsystem, but cannot span multiple storage controller subsystems. Figure 36 Two arrays (A1, A2) and five logical drives (L1 through L5) spread over five physical drives . NOTE: This type of configuration may not apply to all storage systems and serves only as an example. Through the use of basic disks, you can create primary partitions or extended partitions. Partitions can only encompass one LUN.
dynamic disks is unavailable. There could be a potential for data loss depending on the nature of the failed LUN. Volumes are created out of the dynamic disks, and can be expanded on the fly to extend over multiple dynamic disks if they are spanned volumes. However, after a type of volume is selected, it cannot be altered. For example, a spanning volume cannot be altered to a mirrored volume without deleting and recreating the volume, unless it is a simple volume.
Shadow copies should not replace the current backup, archive, or business recovery system, but they can help to simplify restore procedures. For example, shadow copies cannot protect against data loss due to media failures; however, recovering data from shadow copies can reduce the number of times needed to restore data from tape. Using storage elements The last step in creating the element is determining its drive letter or mount point and formatting the element.

5 File server management This chapter begins by identifying file services in Windows Storage Server 2008 R2. The remainder of the chapter describes the many tasks and utilities that play a role in file server management. File services features in Windows Storage Server 2008 R2 Storage Manager for SANs The Storage Manager for SANs (also called Simple SAN) snap-in enables you to create and manage the LUNs that are used to allocate space on storage arrays.
File services management Information about the storage system in a SAN environment is provided in the HP StorageWorks SAN Manuals page located on the HP web site at www.hp.com/go/SDGManuals. Configuring data storage HP StorageWorks X1000 G2 Network Storage Systems are configured only for the operating system. The administrator must configure data storage for the storage system. Configuring additional data storage involves creating arrays, logical disks, and volumes.
Array management utilities Storage devices for RAID arrays and LUNs are created and managed using the array management utilities mentioned previously. For HP Smart Arrays use the ACU. NOTE: The ACU is used to configure and manage array-based storage. Software RAID-based storage systems use Microsoft Disk Manager to manage storage. You need administrator or root privileges to run the ACU.
• A single array can contain multiple logical drives of varying RAID settings. • Extending and expanding arrays and logical drives is supported. The HP Array Configuration Utility User Guide is available for download at http://www.hp.com/ support/manuals. Disk Management utility The Disk Management tool is a system utility for managing hard disks and the volumes, or partitions, that they contain.
Scheduling defragmentation Defragmentation is the process of analyzing local volumes and consolidating fragmented files and folders so that each occupies a single, contiguous space on the volume. This improves file system performance. Because defragmentation consolidates files and folders, it also consolidates the free space on a volume. This reduces the likelihood that new files will be fragmented. Defragmentation for a volume can be scheduled to occur automatically at convenient times.
per-user basis. It is also possible to specify whether or not to log an event when users exceed either their quota warning level or their quota limit. When enabling disk quotas for a volume, volume usage is automatically tracked from that point forward, but existing volume users have no disk quotas applied to them. Apply disk quotas to existing volume users by adding new quota entries on the Quota Entries page.
• Improve performance by increasing the number of spindles in a logical drive volume • Change fault-tolerance (RAID) configurations For more information about RAID levels, see the Smart Array Controller User Guide, or the document titled Assessing RAID ADG vs. RAID 5 vs. RAID 1+0. Both are available at the Smart Array controller web page or at http://h18000.www1.hp.com/products/servers/proliantstorage/arraycontrollers/ documentation.html.
Volume shadow copies NOTE: Select storage systems can be deployed in a clustered as well as a non-clustered configuration. This chapter discusses using shadow copies in a non-clustered environment. The Volume Shadow Copy Service provides an infrastructure for creating point-in-time snapshots (shadow copies) of volumes. Shadow Copy supports 64 shadow copies per volume. A shadow copy contains previous versions of the files or folders contained on a volume at a specific point in time.
NOTE: Shadow copies should not be used to provide access to previous versions of application or e-mail databases. Shadow copies are designed for volumes that store user data such as home directories and My Documents folders that are redirected by using Group Policy or other shared folders in which users store data. Shadow copies work with compressed or encrypted files and retain whatever permissions were set on the files when the shadow copies were taken.
CAUTION: To change the storage volume, shadow copies must be deleted. The existing file change history that is kept on the original storage volume is lost. To avoid this problem, verify that the storage volume that is initially selected is large enough. Identifying the storage area To store the shadow copies of another volume on the same file server, a volume can be dedicated on separate disks. For example, if user files are stored on H:\, another volume such as S:\can be used to store the shadow copies.
NOTE: To check the cluster size of a volume, use the fsutil fsinfo ntfsinfo command. To change the cluster size on a volume that contains data, back up the data on the volume, reformat it using the new cluster size, and then restore the data. Mounted drives A mounted drive is a local volume attached to an empty folder (called a mount point) on an NTFS volume. When enabling shadow copies on a volume that contains mounted drives, the mounted drives are not included when shadow copies are taken.
The shadow copy cache file The default shadow copy settings allocate 10 percent of the source volume being copied (with a minimum of 350 MB), and store the shadow copies on the same volume as the original volume. (See Figure 38). The cache file is located in a hidden protected directory titled “System Volume Information” off of the root of each volume for which shadow copy is enabled. Figure 38 Shadow copies stored on a source volume .
The main advantage to storing shadow copies on a separate volume is ease of management and performance. Shadow copies on a source volume must be continually monitored and can consume space designated for file sharing. Setting the limit too high takes up valuable storage space. Setting the limit too low can cause shadow copies to be purged too soon, or not created at all. By storing shadow copies on a separate volume space, limits can generally be set higher, or set to No Limit.
Set schedules Shadow copy schedules control how frequently shadow copies of a volume are made. There are a number of factors that can help determine the most effective shadow copy schedule for an organization. These include the work habits and locations of the users. For example, if users do not all live in the same time zone, or they work on different schedules, it is possible to adjust the daily shadow copy schedule to allow for these differences.
6. Click Settings. 7. In the Located on this volume field, select an available alternate volume from the list. NOTE: To change the default shadow copy schedule settings, click Schedule. 8. Click OK. 9. On the Shadow Copies tab, ensure that the volume is selected, and then click Enable. Shadow copies are now scheduled to be made on the alternate volume.
3. Click the Shadow Copies tab. See Figure 40. Figure 40 Accessing shadow copies from My Computer . Shadow Copies for Shared Folders Shadow copies are accessed over the network by supported clients and protocols. There are two sets of supported protocols, SMB and NFS. All other protocols are not supported; this includes HTTP, FTP, AppleTalk, and NetWare Shares. For SMB support, a client-side application denoted as Shadow Copies for Shared Folders is required.
SMB shadow copies Windows users can independently access previous versions of files stored on SMB shares by using the Shadow Copies for Shared Folders client. After the Shadow Copies for Shared Folders client is installed on the user's computer, the user can access shadow copies for a share by right-clicking on the share to open its Properties window, clicking the Previous Versions tab, and then selecting the desired shadow copy. Users can view, copy, and restore all available shadow copies.
NFS shadow copies UNIX users can independently access previous versions of files stored on NFS shares via the NFS client; no additional software is required. Server for NFS exposes each of a share's available shadow copies as a pseudo-subdirectory of the share. Each of these pseudo-subdirectories is displayed in exactly the same way as a regular subdirectory is displayed. The name of each pseudo-subdirectory reflects the creation time of the shadow copy, using the format .@GMT-YYYY.MM.DD-HH:MM:SS.
6. Click Restore to restore the file or folder to its original location. Click Copy... to allow the placement of the file or folder to a new location. Figure 42 Recovering a deleted file or folder . Recovering an overwritten or corrupted file Recovering an overwritten or corrupted file is easier than recovering a deleted file because the file itself can be right-clicked instead of the folder. To recover an overwritten or corrupted file: 1.
3. Click either Copy... or Restore. Clicking Restore enables the user to recover everything in that folder as well as all subfolders. Clicking Restore does not delete any files. Backup and shadow copies Shadow copies are only available on the network via the client application, and only at a file or folder level as opposed to the entire volume. Hence, the standard backup associated with a volume backup will not work to back up the previous versions of the file system.
management of the file shares for the supported protocols. Security at the file level and at the share level is also discussed. NOTE: Select servers can be deployed in a clustered or non-clustered configuration. This section discusses share setup for a non-clustered deployment. Folder management Volumes and folders on any system are used to organize data. Regardless of system size, systematic structuring and naming conventions of volumes and folders eases the administrative burden.
2. Click Properties, and then click the Security tab. Figure 43 Properties dialog box, Security tab . Several options are available on the Security tab: • To add users and groups to the permissions list, click Add. Follow the dialog box instructions. • To remove users and groups from the permissions list, highlight the desired user or group, and then click Remove. • The center section of the Security tab lists permission levels.

Click OK. Share management There are several ways to set up and manage shares.
The content of shares should be carefully chosen to avoid two common pitfalls: either having too many shares of a very specific nature, or of having very few shares of a generic nature. For example, shares for general use are easier to set up in the beginning, but can cause problems later. Frequently, a better approach is to create separate shares with a specific purpose or group of users in mind. However, creating too many shares also has its drawbacks.
• Standard shares are shares that do not end in a $ character. Standard shares are listed whenever a CIFS client browses for available shares on a CIFS server. The storage system supports both administrative and standard CIFS shares. To create an administrative share, end the share name with the $ character when setting up the share. Do not type a $ character at the end of the share name when creating a standard share. Managing shares Shares can be managed using Server Manager.
File screening management On the File Screening Management node of the File Server Resource Manager snap-in, you can perform the following tasks: • Create file screens to control the types of files that users can save and to send notifications when users attempt to save blocked files. • Define file screening templates that can be easily applied to new volumes or folders and that can be used across an organization. • Create file screening exceptions that extend the flexibility of the file screening rules.

tower models, the COA label is located toward the rear of the top panel of the server. On blade models, the COA label is located on top of the server or storage blade. Workarounds for common issues The following list documents common issues related to HP StorageWorks X1000 G2 Network Storage Systems and their recommended workarounds.
Issue: The pie chart under Server Manager > Storage Management may indicate a larger amount of disk space than actually exists This issue may occur if both of the following are true: • A hard quota is set and enabled on the root folder of one or more volumes. • A volume with a hard quota on the root folder also has Single Instance Storage (SIS) enabled. This is due to an interoperability issue between directory quotas and SIS.
7 System recovery This chapter describes how to use the System Recovery DVD that is provided with your storage system. The System Recovery DVD The HP StorageWorks Storage System Recovery DVD that is provided with your storage system allows you to install an image or recover from a catastrophic failure. At any later time, you may boot from the DVD and restore the server to the factory condition. This allows you to recover the system if all other means to boot the server fail.
3. Click Restore Factory Image. The upgrade process completes with little user intervention required. The server automatically reboots more than once. IMPORTANT: Do not interrupt the upgrade process. When the upgrade process nears completion, the Windows Storage Server 2008 R2 desktop displays the following message: The user's password must be changed before logging on the first time. Log on to the storage system by establishing an Administrator password: 4. Click OK. 5.
11. Enter format fs=fat32 quick. NOTE: If your USB Flash Drive does not support the FAT32 file system, format the drive as NTFS instead. Omitting the quick parameter lengthens the format time considerably. 12. Enter active to mark the partition as active. 13. Enter assign letter= to assign a drive letter to the USB drive. For example, assign letter=U. 14. Insert the System Recovery DVD provided with the system. 15.
5. Type an Administrator password in the New password box. 6. Re-type the Administrator password in the Confirm password box. 7. Click the blue arrow next to the Confirm password box. 8. Click OK. After the Administrator password has been set, the storage system completes the recovery process. 9. Remove the USB Flash drive from the X Series system or client PC.
