HP StorageWorks P9000 Command View Advanced Edition Suite Software 7.1.1 Administrator Guide (web) (TB581-96065, September 2011)

SolutionProblem and causeNo.
Perform the following procedure to restore the consistency
between the database information and the storage system
status:
1. After restarting the P9000 Command View AE Suite
product services, refresh all storage systems by using
Device Manager.
2. If a migration task was being created or canceled
during an abnormal termination of the Tiered Storage
Manager server, perform the creation or cancellation
again. If an error occurred while a migration was being
canceled, refresh the storage system.
If a migration task that is being executed has failed,
refresh the storage system again. After that, take action
as described below according to the task status.
If data was not deleted:
The migration is complete, and the LDEV numbers of the
migration source and destination have been reversed. Check
the status of the source volume that has the destination
volume LDEV number. If data was not deleted, the original
data remains on the source volume that has the destination
volume LDEV number.
The following action is required:
If the volume that has the destination LDEV number is
blocked:
Use Remote Web Console.
If the volume that has the destination LDEV number is not
blocked:
The data on the volume might not have been deleted. If the
data must be deleted, either format the volume or use the
procedure below to delete the data. Note that the following
procedure assumes that LDEV 10:01 has been migrated to
LDEV 20:01. (Also note that the LDEV numbers of the
volumes have been reversed.)
1. Set a path to LDEV 20:01, and allocate it to a host.
2. From the host, write 0 for the size of the volume to de-
lete any data remaining on LDEV 20:01.
3. Remove the path to LDEV 20:01.
If a migration failed:
Depending on the cause of the error, even if migration
processing has been completed in the storage system, Tiered
Storage Manager or Device Manager might treat the
processing as having failed. As such, do the following:
1. Use Device Manager to refresh all storage systems,
and update the management information in Tiered
Storage Manager and Device Manager. If reserved
volumes remain, their reservation is canceled during
refresh processing.
2. Display the volume information for the migration task
that is in the failed status, and check whether the
volumes have already been migrated. Also, check the
parity group names and storage system names for all
LDEVs at the migration source.
