1 Automated Storage Manager HP StorageWorks X1000 Automated Storage Manager (ASM) is a storage hosting and management tool that radically simplifies: • • • • Hosting storage for applications and shared folders, page 13 Data protection, page 33 Managing storage, page 43 Monitoring storage, page 47 ASM provides storage-allocation wizards that walk you through the process of allocating and configuring storage on your HP Storage System to host application data and shared folders.
File sharing services on local storage See “Using the Create a Shared Folder Wizard” on page 16. Microsoft SQL Server 2000 with SP4 or later, SQL Server 2005 with SP2 or later, and SQL Server 2008* See “Using the Host a SQL Server Database Wizard” on page 17. User-defined applications See “Using the Host a User-Defined Application Wizard” on page 20. * ASM does not support SQL Server 2008 databases that utilize FILESTREAM data type storage. ASM does not support Internet Protocol version 6 (IPv6).
NOTE: If the application server is in a remote location, use Remote Desktop Connection to access the server, copy the Agent installation files, and run the Agent installation. 2. 3. 4. Navigate to the \Automated Storage Manager\Agent folder on the DVD. Double-click asmagentinstaller.exe. Follow the on-screen installation instructions.
Scaling display settings Changing the scaling settings customizes the size at which each application area or shared folder is displayed in the content pane. You can choose to scale each application area and shared folder so that it is displayed in proportion to its capacity (allocated storage size), or so that all the application areas and shared folders are displayed at the same size. 1. In the Actions pane, click Configure Display Options. The Display Options dialog box opens. 2. Click the Scaling tab.
NOTE: Any existing iSCSI connections must be reset before changes take effect. Resetting iSCSI connections If you use the Storage Networks dialog box to configure a preferred private storage network for iSCSI traffic and there are one or more existing iSCSI connections on the system, the new setting will not take effect until the existing connections are reset through iSCSI Initiator on the connected systems. To reset an iSCSI connection: 1.
Automated Storage Manager
2 Hosting storage for applications and shared folders The Automated Storage Manager (ASM) radically simplifies hosting application storage and shared folders on your HP Storage System, using storage-allocation wizards. Use storage-allocation wizards to allocate and configure storage for these applications: Application Description Notes Exchange Allocate and configure storage for one or more Exchange storage group components.
Application Description Notes Allocate and configure storage for any remote application over the iSCSI protocol or any other application that requires storage on the HP Storage System. A wizard assists you in allocating and configuring storage space. User-Defined Applications Data Protection The wizard does not migrate user-defined application data to your HP Storage System or reconfigure the application to store data on your HP Storage System.
1. 2. Do one of the following: • Enter the host name of a server that hosts Exchange (exactly as it is registered in the domain). • Enter the IP address (IPv4) of a server that hosts Exchange. Click Next to open the Select Storage Group Components page (see “Selecting Exchange Server storage group components” on page 15).
NOTE: It is not recommended to host both the LCR and the original Exchange components on a single HP Storage System. Using the Create a Shared Folder Wizard The Create a Shared Folder Wizard walks you through the process of creating a top-level shared folder (file share) on your HP Storage System, including allocating and configuring the required storage. NOTE: You cannot create nested shared folders on your HP Storage System using ASM.
Naming a shared folder Use the Enter a Shared Folder Name and Description page to provide ASM with a name and description for the shared folder. 1. Enter the name for the shared folder. NOTE: The path to the shared folder is created by ASM and is based on the shared folder name. The Share Path field is Read Only. 2. Enter a description of the shared folder (optional). 3. Click Next to open the Set Shared Folder Permissions page (see “Setting permissions for a shared folder” on page 17).
Before you begin configuring storage for SQL Server • Make sure the ASM agent is installed on each server with SQL Server data you plan to host. • Make sure you have a current backup of your SQL Server data and logs. Accessing the Host a SQL Server Database Wizard 1. In the Actions pane, select Host a SQL Server Database. The Host a SQL Server Database Wizard welcome page opens. 2. Click Next to open the Select a SQL Server page (see “Selecting a server that hosts SQL Server” on page 18).
1. Do one of the following: • Select all components (including all of its components) by checking the box next to the component. • Select individual database components by expanding the list and checking the boxes next to the components. You must select all the database components, including the log file, in a database if you want to run backups and/or take snapshots of the database using ASM. NOTE: ASM cannot migrate system databases; for example, ASM cannot migrate master, model, msdb and tempdb.
1. 2. Do one of the following: • Select Transaction processing (TP) for frequently updated, fast growing databases with large volumes of data requiring concurrent user access. • Select Decision support systems (DSS) for databases designed to handle queries on large amounts of data, typically used for data-mining applications. When you are done, click Next to open the Storage Allocation page (see “Allocating space for components” on page 22).
• iSCSI LUN- Exposes a LUN to the remote server so the server can store data on the LUN. You will need to install an iSCSI initiator on your host server. Storage is provisioned for these applications. NOTE: A valid iSCSI Qualified Name (IQN) is required to host a user-defined application as an iSCSI LUN. IP addresses are not valid IQNs.
1. In the name dialog box, type a name for your virtual library. 2. In the Number of slots field, type or use the arrows to indicate how many slots are needed for your virtual library. 3. When you are done, click Next to open the Storage Allocation page (see “Allocating space for components” on page 22). NOTE: The number of slots needed for your virtual library will depend on the media rotation type chosen for the backups that will use the virtual library.
NOTE: After storage space is allocated and configured using a wizard, only the following storage configuration settings can be changed: • Allocated space size • Percent full warning threshold • Enforce Allocated Limit (shared folders and local storage applications) After a logical disk is created, its configuration cannot be changed.
Physical storage Item Description Notes Hot spare required A hot spare is a hard drive reserved as a spare for storage space configured as RAID 1, 1+0, 5, or 6. A hot spare automatically replaces a hard drive when it fails. When the failed hard drive is replaced, its replacement becomes the new hot spare. A hot spare is assigned at the array level. A LUN that does not require a hot spare may be assigned one anyway if another LUN on the same array requires a hot spare.
Customizing RAID levels Before you customize the default RAID level setting, review Table 6 to see how the different RAID levels affect performance, capacity, and data protection level.
RAID level Description RAID 1+0 – Mirroring and Striping Offers the best combination of data protection and performance. RAID 1+0 or drive mirroring creates fault tolerance by storing duplicate sets of data on a minimum of four hard drives. There must be an even number of drives for RAID 1+0. RAID 1+0(10) and RAID 1 are the most costly fault tolerance methods because they require 50 percent of the drive capacity to store the redundant data.
NOTE: For shared folders and local storage applications, you can set an enforceable limit (or quota) for allocated storage, as well as a warning threshold. For more information, see Enforcing an allocated storage limit for shared folders and local storage applications. Enforcing an allocated storage limit for shared folders and local storage applications ASM provides a way to enforce an allocated storage limit for shared folders and local storage applications.
• Tape or Other Device (Alternate location backup) Data is copied off of this HP Storage System to tape, other disks, or other types of storage media. This enables long term storage and disaster recovery. See Scheduling backups on page 29 for more information. • Replication (Live backup) Live data and snapshots (for target HP Storage Systems running ASM) are copied from this HP Storage System to another system that is running HP StorageWorks Storage Mirroring.
Scheduling backups IMPORTANT: • Before you schedule alternate location backups, install a tape library or other physical device and add it to the same Data Protector Express Management Domain as your HP Storage System. • Installing a tape library that can accommodate the media rotation type required by your environment requires tape storage management experience. See http://www.hp.com/sbso/serverstorage/ultimate.html to learn more about tape storage. 1.

Select the backup job for the application or shared folder whose backup schedule you want to edit. 6. Right-click the file and select Properties. See the HP StorageWorks Data Protector Express Users Guide and Technical Reference for more information. Configuring replication 1. On the Data Protection page in any wizard, select Replication.
2. Do one of the following: • To go back and change your selections, click Back. • To run the listed tasks immediately, click Finish. • The Task Viewer opens, running the tasks required to configure storage and migrate data. See Monitoring task completion status for more information. • To schedule tasks to run at a later time, select Schedule tasks to run later, enter a start date and time, and then click Finish. To select AM or PM for the start time, click the up and down arrow buttons.
Cancelling tasks 1. To cancel an uncompleted task, select the task and click Cancel Selected Task. 2. Click Yes to confirm. Tasks canceled after they have started may not cancel immediately. A task will stop running when the last subtask started is completed. All subtasks listed below the last completed subtask are not completed and cannot be restarted.
3 Managing data protection The Automated Storage Manager provides data protection through the use of snapshots, backups, and replication. You can configure these data protection methods through the Data Protection page of ASM's application wizards, or you can configure and modify data protection settings after running the wizards by accessing the Snapshots, Backup and Replication actions in the ASM Actions pane.
6. Enter a start time for snapshots. 7. To add another snapshot to the snapshot schedule, repeat steps 2 through 5. 8. To delete a snapshot from the snapshot schedule, select the snapshot and click Remove. 9. Click OK . Managing snapshots From the Manage Snapshots dialog box, you can take, delete, expose, unexpose, and revert snapshots. NOTE: If replication is enabled and the replication target is an ASM, snapshots are replicated to the target side.
and the Latest data snapshot cannot be exposed while data is being synchronized from the source HP Storage System. The Manage Snapshots dialog box on ASM replication target systems indicates both the Source Date & Time and local (or target) date and time that snapshots are taken. Note that these time stamps are listed in the local time of the replication source and target systems.
1. Select an Exchange storage group, SQL Server database, or user-defined application in the content pane. 2. In the Actions pane, click Snapshots and then click Manage Snapshots. The Manage Snapshots dialog box displays. 3. Select an exposed snapshot from the snapshot list. 4. Click Unexpose. 5. Click Yes to confirm. Reverting data to snapshots ASM allows you to revert data stored on your HP Storage System to a snapshot. This overwrites the existing data and reverts it to a past state.
5. Select a Data Protector Express media rotation type from the list. 6. Type or use the arrows to indicate a time for the backup to begin. 7. For backups to tape or other devices, select the backup device. 8. For local virtual library backups, select the size for the virtual library. A default value will be recommended, based on the selected rotation type and component size. Click Modify advanced storage properties to modify advanced storage settings such as RAID level and stripe size.
Restoring data from backups ASM allows you to restore data to your HP Storage System from the latest backups created using Data Protector Express. You can choose to overwrite the existing data with the backup, or restore the backup to an unused space on your HP Storage System so you can selectively overwrite existing data.
4. Select the restore job for the application or shared folder whose data you want to restore. NOTE: To modify properties of the job, right-click the Restore Job Properties. For example, you may want to choose a different device from which to restore or select different version of files to restore. To restore version for files other than the latest backup, refer to Selecting Files and File Versions in the HP StorageWorks Data Protector Express Users Guide and Technical Reference. 5.
4. 5. 6. Type the Data Protector Express admin password. Type in the new password for the ASMbackup account. Confirm the new password by typing it in again.
