1 Automated Storage Manager Overview This documentation is intended for the person who administers HP StorageWorks X1000 Network Storage Systems running Automated Storage Manager version 4.0 software.
ASM provides storage-management services for the following applications: Table 1 Storage support on ASM Microsoft Exchange Server 2003 with SP1 or later and Exchange Server 2007 See “Using the Host an Exchange Storage Group Wizard” on page 14. 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.
• iSCSI LUN volumes greater than 2TB are supported only if the iSCSI Target is running a minimum of iSCSI Target version 3.2. • The maximum size allowed for a LUN is 256TB. IMPORTANT: If you want to grow existing MBR partitions to a size exceeding 2TB, you must first convert the MBR partition to a GPT partition. This can be accomplished by backing up the data on the MBR partition and then deleting the MBR partition. A new GPT partition can then be created and the data can be restored.
1. 2. 3. Click on Add HP Storage System in the Actions pane. A dialog box will open. Enter the hostname or IP address (IPv4) of the HP Storage System to add. The added HP Storage System will appear in the Navigation pane. Remove an HP Storage System To remove an added HP Storage System: 1. 2. 3. Click on Remove HP Storage System. A window will appear, asking if you would like to remove the HP Storage System. Click Yes.
Configure Application Credentials Use the Application Credentials dialog box to set or update user name and password security credentials applicable to the HP Storage System. 1.

Click Add.
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. From this window, you can also click Modify advanced properties to configure advanced settings for backups.
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.
