6 Using RAID Manager for Manual
Volume Migration
In the environment where Auto LUN is installed on the storage system, users can use RAID Manager to
perform manual volume migration from an open-system host. This appendix explains the procedure and
notes for using RAID Manager to perform manual volume migration.
Sample Volume Migration
This section illustrates with a example the procedure when performing manual volume migration by using
commands of RAID Manager. In this example, It is assumed that group1 means the group name in
the RAID Manager configuration definition file and pair1 means the name of the volume which pair
is target of the operation. For details on RAID Manager operation, see HP StorageWorks XP RAID
Manager User’s Guide.
To perform manual volume migration by using RAID Manager:
1. Start RAID Manager.
2. Type the following command for a SMPL pair to start volume migration:
paircreate −g group1 −d pair1 −m cc
−vl
When volume migration starts, the status of the pair changes to COPY.
3. Type the following command to check the status of the pair:
pairdisplay −g group1 −d pair1 -fcex
When the volume migration completed, the status of the pair becomes PSUS. When the volume
migration failed, the status of the pair becomes PSUE.
4. When the status of the pair becomes PSUS or PSUE, return the pair status to SMPL by the
following command:
pairsplit −S −g group1 −d pair1
Note: When the migration failed (the status of the pair becomes PSUE), repeat step 2 and 3 . When it
still becomes PSUE, contact the service engineer.
The status transition chart of a pair when the volume migration is performed by using RAID Manager
is shown below. The statuses in this chart can be displayed by typing pairdisplay command of RAID
Manager.
