Creating Thin Image pairs and defining them in snapshot or
consistency groups using CCI
You can create pairs and define the pairs in a snapshot group or in a
consistency group. Define pairs to consistency groups to perform pair tasks
on all of the pairs within the group. This task describes how to do this using
CCI.
Note:
If the host is down, the CCI command might be rejected and the pair
not defined in the group. In this case, you can use Device Manager - Storage
Navigator to create the pair and assign it to a group.
Procedure
1.
Create the Thin Image pair and define the pair in a snapshot or
consistency group. To do this using CCI, run the
raidcom add snapshot
command.
Note:
Define pairs that share the same P-VOL in different
snapshot groups.
The following is an example of using the CCI
raidcom
command to create a
pair specifying the P-VOL (LDEV#10:10), the S-VOL (LDEV#20:20), the pool
