HP StorageWorks XP Remote Web Console Software - Manual (Page 55)

When a volume starts migration, the % (percentage) column displays the progress of the
migration. When the migration finishes, the migration plan of that volume will disappear from
the list.
If execution of the migration plan created by application software other than Remote Web
Console has failed, PSUE is displayed in the Stat column. In this case, you must check the
status of the application software that created the migration plan.
NOTE:
•
Up to eight migration plans can be applied with each click of the Apply button. To create
and apply more than eight migration plans, use the Apply button several times. While
executing the migration plans, you can apply additional migration plans.
•
The number of migration plans that can be executed concurrently might be restricted
depending on the usage of other storage system programs, and also depending on the
emulation types and sizes of the migrated volumes.

To delete a migration plan, select a migration plan in the list, and then click the Delete button.
•
If you select a migration plan in black (a migration plan that is waiting for execution or being
executed), and then click the Delete button, the character D appears in the DEL column, and
the migration plan will not be deleted until you click the Apply button.
•
You cannot use the Delete button to delete migration plans executed by programs other than
XP Auto LUN. These migration plans are indicated by the (green) icon displayed in the
LDEV column and by Other[XX] displayed in the Owner column in the Target LDEV list. These
migration plans also disappear from the list when the migration finishes.
CAUTION:
•
If you delete a migration plan that is being executed, the data in the target volume will not
be guaranteed.
•
When an error condition exists in the storage system, resource usage can increase or become
unbalanced. Do not use usage statistics collected during an error condition as the basis for
planning XP Auto LUN operations.
Automating Volume Migrations
You can set volume migrations to automatically take place every day at the specified time. This
section describes the procedure for automating volume migrations.
NOTE: XP Auto LUN cannot perform auto migration using external volumes and volumes reserved
by a program other than XP Auto LUN.
Setting a Fixed Parity Group
A fixed parity group is a parity group that cannot be affected by auto migration operations. To
exclude a parity group (all volumes in the group) from auto migration operations, you need to fix
the parity group. Volumes in fixed parity groups are not used for auto migration operations, but
can be used for manual migration operations.
To fix a parity group so that it cannot be migrated manually:
