HP P9000 Tiered Storage Manager Software 7.2 Release Notes

• If the configuration of a volume registered to a migration group was changed, an attempt to
remove the volume from the migration group might have generated the KATS50243–E message.
Additionally, an operation to delete the migration group might have generated the KATS50242–E
message.
• Relocation might not succeed when stop-monitoring tasks with relocation of the period is scheduled
through a monitoring template.
Important considerations
Data migration
When a data migration task is running, and if data migration does not complete because, for example,
I/O is in progress on the source volume, Tiered Storage Manager may not be able to detect the data
migration task error. At this time, the task continues to run with status incomplete and cannot be stopped
from the Tasks tab.
In this case, follow these steps to stop the data migration task, and then retry the migration task:
1. Prepare to use the CLI.
Set up the CLI environment by following instructions in the HP P9000 Command View Advanced
Edition Suite Software CLI Reference Guide.
2. Check the migration pair status.
Execute the GetMigrationPair command, and then make sure that the status of the migration
pair is failure (status=2).
See the CLI command help for details about the GetMigrationPair command.
For example, to perform data migration from 00:0A:01 to 00:0A:02 on a P9500 with a serial
number of 12345, enter the following command:
>HiCommandCLI GetMigrationPair model=P9500 serialnum=12345
sourcedevnum=00:0A:01 targetdevnum=00:0A:02
When the status is failure, the command displays information like the following:
An instance of MigrationPair
objectID=VOLUMEMIGRATION.P9500.12345.2561.2562
sourceDevNum=00:0A:01
targetDevNum=00:0A:02
status=2
progress=0
ownerID=255
When the status is running, the command displays information like the following:
An instance of MigrationPair
objectID=VOLUMEMIGRATION.P9500.12345.2561.2562
sourceDevNum=00:0A:01
targetDevNum=00:0A:02
status=3
progress=40
ownerID=255
If the status of the migration pair is failure, perform the tasks in steps 3, 4, and 5. If the status is
not failure, do not perform any steps, and wait until the data migration task completes with the
failure status.
