A Using RAID Manager for manual Auto LUN
Use RAID Manager to perform manual migration operations from an open-system host.
Auto LUN and RAID Manager commands
The following figure illustrates the different states of Auto LUN pairs when using RAID Manager
commands.
Figure 9 Auto LUN Pairs and RAID Manager Commands
The status of a pair can be checked by using the pairdisplay RAID Manager command.
Migrating volumes manually with RAID Manager
In this example, group1 represents the group name in the RAID Manager configuration definition
file, and pair1 represents the name of the volume whose pair is the target volume of the operation.
Procedure 11 To perform a manual migration using RAID Manager commands:
1. Start RAID Manager.
2. Type the following command for a SMPL pair to start volume migration:
paircreate -g group1 -d pair1 -m cc -v1
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 volume migration completes, the status of the pair changes to PSUS. If volume migration
fails, the status of the pair changes to PSUE.
4. Type the following command to change the pair status back to SMPL:
pairsplit –S –g group1 –d pair1
If the migration fails (the status of the pair becomes PSUE), repeat steps 2 and 3. If you are
unable to change the pair status back to SMPL, contact HP Technical Support.
