Creating Log Units and Association Sets (optional)
In this example, hypothetical disks 50100 and 60100 are used as the mirrorset for the log
disk. The log unit is D10. The association set name is AS_D1. The association set is using
remote copy set name RC_D1.
Creating a Log Unit
1. Create a mirrorset for the log disk by issuing the following CLI command:
ADD MIRRORSET MirrorsetName DiskName
Example: ADD MIRR MIR_D1LOG DISK50100 DISK60100
2. Initialize the mirrorset with the following CLI command:
INITIALIZE ContainerName
Example: INITIALIZE MIR_D1LOG
3. Verify that you have created a mirrorset by issuing the following CLI command:
SHOW MIRRORSET
You should see a display similar to the following:
Name Storageset Uses Used by
-----------------------------------------------------------------------
MIR_D1LOG mirrorset DISK50100
DISK60100
4. Present the log unit to the controller with the following CLI command:
ADD UNIT UnitName ContainerName
Example: ADD UNIT D10 MIR_D1LOG
5. Verify that the controller recognizes the log unit by issuing the following CLI
command:
SHOW UNITS
You should see a display similar to the following:
