7 Troubleshooting Automated Storage Manager

The following list documents recommended workarounds for conditions related to Automated

Storage Manager. For information specific to a particular product release, see the HP Automated

Storage Manager Release Notes for your product version.

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.

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.

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

This section describes workarounds for conditions 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

applies only to storage systems with DPX installed and enabled.

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.

Changes made to a backup using Data Protector Express are not always reflected in ASM

If you use Data Protector Express to change the rotation type associated with a backup to Custom rotation, the change

is not reflected in ASM.

Workaround: Data Protector Express can be used to change the rotation type of a backup to Custom rotation, however,

this change will not be reflected in ASM. If you need to use a custom rotation, HP recommends that you continue to

use Data Protector Express to make any further changes to the backup.
