About this guide
1 Overview HP StorageWorks All-in-One Storage Manager (ASM) is a storage hosting and management tool that radically simplifies: • • • • Hosting storage for applications and shared folders, page 19 Configuring data protection, page 37 Managing storage, page 41 Monitoring storage, page 47 ASM provides storage-allocation wizards that walk you through the process of allocating and configuring storage on your HP All-in-One Storage System to host application data and shared folders.
Microsoft SQL Server 2000 and 2005 See “Using the Host a SQL Server Database Wizard” on page 22. User-defined applications See “Using the Host a User-Defined Application Wizard” on page 24. Microsoft iSCSI Target and Data Protector Express are required to host application storage and create backups using ASM. Microsoft iSCSI Target and Data Protector Express comes preinstalled on your HP All-in-One Storage System. A license key is not required for Microsoft iSCSI Target.
Figure 1 Application storage infrastructure NOTE: The iSCSI communication path is transparent to the application, application server, and Windows Explorer. The application, application server, and Windows Explorer believe the data is stored on the application server. So, to view the application data, you must navigate to the iSCSI LUN(s) on the application server, not the LUN(s) on your HP All-in-One Storage System, using Windows Explorer. ASM provides automated data migration for Exchange and SQL Server.
Figure 2 Shared folder storage infrastructure ASM discovers any top-level and nested shared folders on your HP All-in-One Storage System during setup and afterwards on an ongoing basis. ASM allows you to monitor and manage any top-level shared folders created on your HP All-in-One Storage System using ASM or other applications, such as Windows Explorer or the Shared Folder MMC snap-in.
Toolbar The toolbar, located just below the menu bar in the ASM main window, is the MMC toolbar. See the MMC online help for more information. To open MMC online help, click Help in the Actions pane. Navigation pane The Navigation pane, located on the left side of the ASM main window, allows you to quickly navigate between HP All-in-One Storage Management applications.
Menu Description Storage Utilization View Displays the allocated storage values for specific applications and the shared folders pool, the unallocated storage value, and the storage value for data not managed by ASM in a pie chart. See “Storage Utilization View” on page 61 for more information. Tools > Task Viewer Opens the Task Viewer, where you can view the: • Status of tasks completed or scheduled to run in the future. • All tasks that failed and the errors reported.
Menu Description folder properties” on page 48, “Accessing storage area properties” on page 57, and “Accessing application server properties” on page 60 for more information.* Data Protection Opens the Data Protection tab of the Properties window where you can schedule backups, run a backup, or restore data from a backup. You can also schedule snapshots, take a snapshot, expose a snapshot, or revert data to a past snapshot. See “Configuring data protection” on page 37 for more information.
Overview
2 Hosting storage for applications and shared folders The All-in-One Storage Manager (ASM) radically simplifies hosting application storage and shared folders on your HP All-in-One Storage System, using storage-allocation wizards. Use storage-allocation wizards to allocate and configure storage for these applications: Application Description For more information Exchange Allocate and configure storage for individual Exchange storage group components.
Using the Host an Exchange Storage Group Wizard The Host an Exchange Storage Group Wizard automatically discovers the Exchange storage groups in your network domain and helps you allocate and configure storage space for these components: • Mail stores—Contain the data in user mailboxes. • Public stores—Contain the data in public folders. • Logs—Provide a record of every message stored in a storage group.
The table below lists the action ASM will perform for each storage group component selected. Table 4 Selecting storage group components to host 2. Action Description None Component's check box is not selected, so ASM will not perform any action. Select check box to change action. Allocate Space Component's data is already hosted on your HP All-in-One Storage System. The component was removed from view. The component will be returned to view.
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).
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). Selecting a server that hosts SQL Server Use the Select a SQL Server page to select one of the servers that hosts SQL Server discovered on your domain by the wizard. 1. 2. Do one of the following: • Enter the host name of a server that hosts SQL (exactly as it is registered in the domain). • Enter the IP address of a server that hosts SQL.
2. To view the properties for a database component, select the database component name and then click Properties. See “Data file properties” on page 54 and “Log file properties for database” on page 54 for descriptions of the properties displayed. 3. If you do not want ASM to delete the original files for the selected database components from the server that hosts SQL Server after it migrates the data to your HP All-in-One Storage System, clear the Delete original files after checkbox. 4.
NOTE: You need to know the path to the iSCSI LUN on the application server to configure the remote application to store data on the iSCSI LUN. The path to the iSCSI LUN is displayed on the application's Properties window on the Storage tab.
NOTE: The default allocated space size (15 MB) is the minimum value that can be allocated. You cannot set the size below the minimum value. NOTE: SQL Server and Exchange default advanced configuration settings are based on SQL Server or Exchange, and HP storage best practices, and should generally not be changed. 1. Do one of the following: • Click Next to accept the default values that ASM has provided for the components, user-defined application, or shared folder selected.
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 only) The other advanced configuration settings cannot be changed due to the nature of how hard drives work. Once a logical disk is created, its configuration cannot be changed.
Item Description Notes RAID Level Hard drive formatting that provides different levels of performance, capacity, and data protection. For more information about RAID levels, see “Customizing RAID levels” on page 29.* RAID Stripe Size The number of bytes or kilobytes of data in each RAID stripe (block of data). The RAID stripe size selected affects performance. For the best performance, select the stripe size closest to the size of the files being saved.
Customizing RAID levels Before you customize the default RAID level setting, review Table 7 to see how the different RAID levels affect performance, capacity, and data protection level.
RAID level Description not interrupted. RAID 1+0(10) can withstand multiple simultaneous drive failures, as long as the failed drives are not mirrored to each other. RAID 5 – Distributed Data Guarding Offers the best combination of data protection and usable capacity while also improving performance over RAID 6. RAID 5 stores parity data across all the physical drives in the array and allows more simultaneous read operations and higher performance than data guarding.
If the capacity of the shared folder surpasses the percent full warning threshold and reaches the allocated space limit, the file folder status changes from Warning to Critical in the content pane, and users are blocked from adding data to this shared folder.
NOTE: Snapshots taken of a shared folder include all the other shared folders on the same volume, because snapshots are taken at the volume level. See “Storage View” on page 56, for information on viewing volumes. Selecting data protection is optional. To select data protection after storage is allocated, see “Configuring data protection” on page 37.
Any custom media rotation types you create in Data Protector Express are also listed in the Rotation Type drop-down menu. NOTE: Backups are performed on business days (Monday through Friday) at 11:00 p.m. by default. For information on changing the default schedule of the media rotation types, see Changing the default backup schedule.
Scheduling snapshots 1. Click the box on the right side of the Schedules box to open the Snapshot Schedule page. 2. Click Add to add a snapshot to the snapshot schedule. 3. Select a snapshot frequency (hourly, daily, weekly, monthly) for snapshots. 4. Enter a start date for snapshots. 5. Enter a start time for snapshots. 6. To add another snapshot to the snapshot schedule, repeat steps 2 through 5. 7. To delete a snapshot from the snapshot schedule, select the snapshot and click Remove. 8.
NOTE: Click the Expand tree icon next to a task to view its subtasks. Select a task to view its description in the Details box on the Task Viewer. The Task Viewer has a filter drop-down menu. Each selection displays information about task-completion status for different time periods: • Show All—Displays all tasks that have been completed or failed to complete. Displays the tasks and subtasks currently being processed and all scheduled tasks.
1. Using ASM, determine the path to the iSCSI LUN (logical disk) created on the application server by ASM, as follows: a. From the Filters drop-down menu, select User-Defined or All. b. Select the user-defined application in the content pane. c. In the Actions pane, select Properties. The Properties window opens. 2. d. Click the Storage tab. e. Record the Application Path information displayed. Copy the application data to the path on the application server recorded in step 1 as follows: a.
3 Configuring data protection Use the Data Protection tab on any Properties window to do the following: • Select a media rotation type for backups or run a backup of an Exchange storage group, SQL Server database, user-defined application, or shared folder. See “Scheduling and running backups” on page 37. • Create a snapshot schedule, take a snapshot, or delete a snapshot of an Exchange storage group, SQL Server database, user-defined application, or shared folder.
Scheduling, taking, and deleting snapshots 1. Do one of the following: 2. • Select an Exchange storage group (or a component of a storage group) in the content pane to schedule, take, or delete snapshots of the Exchange storage group. • Select an SQL Server database (or a component of the database) in the content pane to schedule, take, or delete snapshots of the SQL Server database.
c. Enter the expose path on the application server where you will view the snapshot. Using Windows Explorer, navigate to the expose path to view the snapshot. 4. To unexpose a snapshot: a. Select an exposed snapshot from the snapshot list. b. Click Unexpose. c. Click Yes to confirm.

4 Managing storage After an application is hosted or shared folder is created on your HP All-in-One Storage System using a storage-allocation wizard, you can manage its storage and data by: • • • • • • • • Increasing or reducing the allocated storage, page 41 Changing the percent full warning threshold, page 42 Removing application areas from view, page 42 Restoring application areas to view, page 43 Changing permissions, names, descriptions, or paths of shared folders, page 44 Deleting shared folders, pag
setting for an application component, the maximum value for Size Range is recalculated for each application component shown. NOTE: To change the percent full warning threshold and/or enforce allocated limit (shared folders only) setting, click Advanced. See “Selecting advanced configuration settings” on page 27 for more information. 4. Click Next to open the Review Tasks Summary page (see “Reviewing task summary and scheduling tasks” on page 34).
Removing an application component or user-defined application from view removes the application component selected in the content pane from view, which removes your ability to manage and monitor the application component or user-defined application's storage using ASM. Removing an application component or user-defined application from view does not unhost its storage. Its storage is still hosted on your HP All-in-One Storage System. NOTE: This action is not available for shared folders.
To be able once again to manage and monitor a user-defined application's storage using ASM, you must unhost the user-defined application's storage, use the Host a User-Defined Application Wizard to allocate new storage, manually migrate the application data to your HP All-in-One Storage System, and then configure the user-defined application to save its data to the newly allocated storage on your HP All-in-One Storage System.
3. • In the Action pane, click Properties and then select the Data Protection tab. Click Restore from backup to launch the wizard and open the Restore Source Device page (see Selecting the source device). Selecting the source device 1. Select the DVD-RW drive on your HP All-in-One Storage System, tape library, or virtual library where the backup is saved. 2. Click Next to open the Restore Destination page (see Selecting the restore destination). Selecting the restore destination 1.
5. Right-click the restore job and click Run to perform the restore. 6. Click Yes to confirm the restore. To view the status of the restore job, click Job Status in the Favorites pane. 7. Exit Data Protector Express. Reverting data to past snapshots ASM allows you to revert data stored on your HP All-in-One Storage System to a past snapshot. This overwrites the existing data and reverts it to a past state. NOTE: Snapshots of shared folders cannot be reverted to past snapshots using ASM.
