1 All-in-One Storage Manager 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 11 Data protection, page 31 Managing storage, page 41 Monitoring storage, page 45 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.
ASM provides storage-management services for the following applications: Table 1 Software support Microsoft Exchange Server 2003 with SP1 or later and Exchange Server 2007 See “Using the Host an Exchange Storage Group Wizard” on page 12. File sharing services on local storage See “Using the Create a Shared Folder Wizard” on page 14. 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 15.
2. Select an item in the Items list and a color in the Color drop-down menu. 3. When your color selections are complete, click Apply to apply the color settings to the content pane. 4. Click OK. Scaling display settings Changing the scaling settings customizes the size at which each application area or shared folder is displayed in the content pane.
To configure storage networks for iSCSI traffic: 1. Under Preferred Storage Network, select a network that will be designated to manage all iSCSI traffic. 2. Under Available for Failover, select a network that can be used to manage iSCSI traffic in the event that the preferred storage network fails. In the event of iSCSI initiator failure, iSCSI traffic fails over to the designated network. NOTE: Any existing iSCSI connections must be reset before changes take effect.
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 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 All-in-One 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 All-in-One Storage System or reconfigure the application to store data on your HP All-in-One 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 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 13).
NOTE: It is not recommended to host both the LCR and the original Exchange components on a single All-in-One 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 All-in-One Storage System, including allocating and configuring the required storage. NOTE: You cannot create nested shared folders on your HP All-in-One Storage System using ASM.
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 15). Setting permissions for a shared folder Use the Set Shared Folder Permissions page to set network user read and write permissions for the shared folder.
• 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 16).
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 20).
recommended option for most scenarios. The All-in-One Storage Manager agent must be installed on the application server to use this option. • 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. • Local storage only- Creates a volume on your All-in-One Storage System. Storage is provisioned for these applications. 2.
3. When you are done, click Next to open the Storage Allocation page (see “Allocating space for components” on page 20). 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. The number of slots must be high enough to support the rotation type you intend to use for scheduling backups to this 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 5 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.
• Replication (Live backup) Live data is copied from this All-in-One Storage System to another system that is running HP StorageWorks Storage Mirroring. See Configuring replication for more information. From this window, you can also click Modify advanced properties to configure advanced settings for backups and replication.
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 All-in-One 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.

6 Troubleshooting, servicing, and maintenance Troubleshooting the storage system Use the references and general guidelines in this section to troubleshoot your HP StorageWorks All-in-One Storage System. Operating system problems and resolutions Use the suggestions below to help resolve operating system issues. Table 31 Operating system problems Problem Action Operating system locks up Scan for viruses with an updated virus scan utility. General protection fault (GPF) occurs.
3. Install the current drivers. Application software problems If your application software locks up, perform the following actions: • • • • • Check the application log and operating system log for entries indicating why the software failed. Check for incompatibility with other software on the server. Check the support web site of the software vendor for known problems. Review the log files for changes made to the server that may have caused the problem.
The following table lists all possible ASM alerts and provides descriptions, possible causes, and solutions for each alert. Table 32 Alert descriptions Object Any application component, user-defined application, or shared folder Alert text Description Possible cause Solution Used space cannot be determined. Directory permission is preventing ASM from determining the used space or the logical disk has failed. An alert will be issued for the logical disk if it has failed.
Object Alert text Any application Exchange storage group Possible cause Solution Credentials failure on . Go to the Application Credentials dialog to specify the credentials for this application. Credentials for the application server on the remote system may not be set or may have expired. Use the Application Credentials dialog box to specify the credentials for this application. See “Configure Application Credentials” on page 9 for more information.
Object Alert text Description The Exchange Database and the Streaming Database are on different volumes. Possible cause Solution The Host an Exchange Storage Group Wizard typically migrates both of these databases to the same volume to ensure snapshot consistency. This may affect your ability to back up and restore this component. Use Exchange tools on your Exchange server to migrate the streaming database to the same volume as your Exchange database. Exchange MailStore This mailstore is offline.
Object Alert text Description Share not found at given path. Possible cause Solution The share may have been manually removed from this path. Remove this component from view or manually create the share at the same path. SQL Server Data File This data file could not be found in the database '' on host '' . The database exists but the data file cannot be found. File has been moved or deleted. Restore file or revert file using snapshot.
Object Alert text Description Possible cause Solution Health: Failed redundancy but one mirror still working Logical disk is configured as RAID 1 or RAID 1+0(10). One of the pair of mirrored hard drives has failed but the other hard drive is still working. Hard drive has failed. Replace failed hard drive immediately to restore redundancy. Health: Failed redundancy, the last mirror is failing Logical disk is configured as RAID 1 or RAID 1+0(10).
Object Replication 72 Alert text Description Health: Resyncing mirrors or rebuilding parity. This logical disk is currently rebuilding. During this time you may notice a performance degradation. Possible cause Solution Health should return to normal. You can use the tools available with the HP Array Configuration Utility to view any logs that may explain what caused this problem. An incompatible version of HP StorageWorks Storage Mirroring is installed on this server. Only SWSM version 5.0.
Object Alert text Possible cause Solution A manual remirror is required. The contents of the replication target changed outside of normal replication. Use the StorageWorks Storage Mirroring Management Console to initiate a mirror operation manually. Replication target is not consistent with the source. The replication target does not contain the same information as the source. Use the StorageWorks Storage Mirroring Management Console to initiate a mirror operation manually.
Object iSCSI Target Alert text Possible cause Solution The replication license state for this system could not be determined. An invalid license key was entered for StorageWorks Storage Mirroring. Obtain a valid license key and use the SWSM Management Console to enter the new license key. iSCSI Target Software not running or not of minimum version. ASM requires Microsoft iSCSI Target version 3.1 or greater. iSCSI LUN contains multiple host references. Multiple hosts are not supported.
NOTE: Snapshots cannot be used to recover data lost as a result of logical disk failure. Snapshots of Exchange storage groups, SQL Server databases, user-defined applications, and shared folders are stored on the same logical disks as the original data, and therefore are also lost. Maintenance updates Regular updates to the storage system are supplied on the HP All-in-One Storage System Service Release DVD. The Service Release DVD can be obtained at http://www.software.hp.com.
Firmware updates Firmware is software that is stored in Read-Only Memory (ROM). Firmware is responsible for the behavior of the system when it is first switched on and for passing control of the server to the operating system. When referring to the firmware on the system board of the server, it is called the System ROM or the BIOS. When referring to the firmware on another piece of hardware configured in the server, it is called Option ROM.
