A Using RAID Manager for Auto LUN
Use RAID Manager from an open-system host to perform migration operations on open-system and
mainframe volumes.
Auto LUN and RAID Manager commands
The following figure illustrates the different states of Auto LUN pairs when using RAID Manager
commands.
Figure 5 Auto LUN Pairs and RAID Manager Commands
The status of a pair can be checked by using the pairdisplay RAID Manager command.
Migrating volumes 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 5 To perform a 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 step 2 and 3. If you are
unable to change the pair status back to SMPL, contact the service engineer.
Interoperability of Auto LUN and RAID Manager
When you perform an Auto LUN plan by using RAID Manager commands, note the following:
•
A volume reserved through Auto LUN cannot be used as a target volume
•
A migration plan being executed by Auto LUN cannot be canceled using RAID Manager
•
A migration plan created by Auto LUN cannot be displayed using RAID Manager
•
Click File > Refresh All on the menu bar of the Remote Web Console main window to check
RAID Manager settings in Remote Web Console
•
While the microcode is being downgraded or upgraded, users must not perform any operations
that the resulting microcode would not support
