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.
Problema: 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.
Solución: Retry the operation after completing the Discovery process.
Problema: 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)
Solución: 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.
Problema: 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.
Solución: 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.
