7 Troubleshooting Automated Storage
Manager issues
The following list documents common issues related to Automated Storage Manager and their
recommended workarounds. For issues and workarounds specific to a particular product release, see
the HP Automated Storage Manager Release Notes for your product version.
Issue: The ASM Grow/Extend Volume command fails intermittently.
The Grow/Extend Volume command sometimes returns a failure even though the operation completes successfully
and the volume capacity matches the requested size.
Workaround: Retry the operation after completing the Discovery process.
Issue: Backup and/or Restore operations in ASM may fail if there is more than one File Volume (partition)
configured on an iSCSI-Based LUN (disk)
Workaround: Do not perform backup or restore operations in ASM on storage where more than one File
Volume is hosted on a single iSCSI LUN. ASM never provisions more than one volume on iSCSI LUNs, and
this situation will not be encountered for storage provisioned by ASM.
Issue: Data protection settings are not modified for storage areas that are promoted by ASM
If data protection settings (snapshots and backup) are applied to a remote user-defined storage area, and
then a SQL Server database or Exchange database is manually migrated to this storage area, ASM automatically
promotes the application to a SQL or Exchange Storage area during the discovery process. ASM does not,
however, adjust the data protection settings that were originally applied to the area. This may lead to failures
when taking snapshots or running backups.
Workaround: When SQL Server or Exchange databases that are part of user-defined storage areas are
promoted to SQL or Exchange storage areas in ASM, disable and delete all data protection settings for those
areas (snapshots and backup) and reset them using ASM.
Troubleshooting Data Protector Express issues
This section describes issues related to HP StorageWorks Data Protector Express (DPX), a service
required to enable data protection features on the HP ASM. Note that DPX is not installed on HP
StorageWorks X1000 Network Storage Systems by default. The following issues apply only to storage
systems with DPX installed and enabled.
Issue: DPX Virtual Tape Libraries show up as User Defined Applications in ASM after running System Recovery
DPX Virtual Tape Libraries that are not backed up prior to running the System Recovery process appear as
User-Defined Applications in the ASM UI after the system recovery process is complete.
Workaround: Before running System recovery, back up all DPX files and configuration settings and reapply
them after the System Recovery process is complete.
