Issues and workarounds
Automated Storage Manager (ASM)
This section describes issues related to HP Automated Storage Manager (HP ASM) version 3.9.0.
Issue: ASM backup of iSCSI based application server data fails on X1000 Network Storage Systems running
Windows Storage Server 2008 SP2.
ASM provides integrated backup of iSCSI LUNs that are presented as volumes to application servers. The
ASM agent installed on the application server initiates a VSS snapshot of the iSCSI volumes. This results in an
application-consistent snapshot on the storage server that is temporarily mounted on the storage server, giving
backup software access to the files; however, the attempt to mount the snapshot on the storage server fails,
which causes the backup job to fail.
Workaround: This problem is currently under investigation. Until a solution is implemented, one of the following
workarounds is required to back up application data held in iSCSI volumes.
Option 1: Back up data from the application server. From the application server, the iSCSI storage appears
as normal Windows volumes mounted at drive letters or mount paths. Use normal procedures for backing up
these volumes. Depending on the backup software used, there may be a conflict with the VSS Hardware
Provider on the application server. If there are backup errors, try disabling the VSS Hardware Provider: click
Start >Administrative Tools > Services. Double-click Microsoft iSCSI Software Target VSS Hardware Provider.
Stop the service if it is running, and set the Startup Type to Disabled.
Option 2: Schedule or manually create snapshots of iSCSI LUNs (virtual disks) on the storage server using
Microsoft iSCSI Software Target. These snapshots can then be mounted locally on the storage server giving
backup software access to the files. Refer to Microsoft iSCSI Software Target help for more detail on automating
this process. Go to Start > Administrative Tools > Microsoft iSCSI Software Target. Select Help Topics from the
Help menu and navigate to the Managing Backup and Recovery for Virtual Disks topic.
NOTE:
Backups created in this manner are crash consistent, meaning that the application is not given the
opportunity to acquire its data for the backup. If the backup is used for recovery, extra steps such as
replaying logs may be required. For an application consistent backup, use option 1 above and use
VSS-aware backup software.
Issue: When updating older versions of ASM to ASM version 3.9.0, some initiated tasks are not always shown
in the ASM Task Viewer.
Workaround: Restart the storage system. After the restart, all tasks are visible in the ASM Task Viewer.
Issue: Adding a storage system from ASM fails with a Cannot contact server error.
When attempting to add a storage system to ASM using the Add HP Storage System function in the ASM
Actions pane, the action sometimes fails with the following error message: The server could not be contacted.
Please verify that the HP Automated Storage Manager server is running.
Workaround:
1. Ensure that the ASM server and client are both running the same version of ASM.
2. Configure the ASM server and client firewall for exceptions on ports 12550 and 12551.
