5 Using RAID Manager for Manual Volume Migration
In the environment where XP Auto LUN is installed on the storage system, users can use RAID
Manager to perform manual volume migrations from an open-system host. This chapter explains
the procedure and notes for using RAID Manager to perform manual volume migrations.

Sample Volume Migration
Using an example, this section provides the procedure for performing a manual volume migration
using RAID Manager commands. In this example, group1 indicates the group name in the RAID
Manager configuration definition file, and pair1 indicates the name of the volume whose pair is
the target of the operation. For details on RAID Manager operations, see the HP StorageWorks
XP RAID Manager User Guide.
To perform manual volume migration by using RAID Manager:
1. Start RAID Manager.
2. Type the following command for an SMPL pair to start a volume migration:
paircreate −g group1 −d pair1 −m cc −vl
When the 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 completes, the status of the pair becomes PSUS. If the volume
migration fails, 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: If the migration fails (the status of the pair becomes PSUE), repeat step 2 and step 3 . If
it still becomes PSUE, call HP technical support.
The status transition chart for a pair when the volume migration is performed by using RAID Manager
is shown in
Figure 29 (page 67) . The statuses in this chart can be displayed by using the
pairdisplay command of RAID Manager.
