Create Thin Image pairs in the Create TI Pairs window in HDvM - SN, or by using the raidcom add snapshot command in CCI.
When creating a Thin Image pair, you need to specify the pool to be used for the pair. If multiple Thin Image pairs share the same primary volume, the pairs must also share the same pool. For example, if you specify three secondary volumes for one primary volume, you must specify the same pool for the three Thin Image pairs.
If you release a Thin Image pair, the volume status becomes SMPL. Immediately after a volume becomes SMPL, you cannot use the volume to create a Thin Image pair. If you want to create Thin Image pairs using SMPL volumes, you should wait for a while before creating the pairs. The wait time required depends on your system environment.
You can check the status of volumes in the Local Replication window and the View Pair Properties window in HDvM - SN, or by using the raidcom get snapshot command in CCI.
