volume, the data consistency is not guaranteed by the pairsplit command (including
pairsplit -FMRCF) of the continuing I/O.
• Registration and limitations of the number of CTGID
When a pair creating, the RAID Manager maps and assigns the configuration definition file
group to CTGID managed by storage system equiptment. The maximum number of the group
that can be resistered to the storage system is 128 (from 0 to 127 for group ID). If resistered
over 128, the pair creation will be terminated with EX_ENOCTG error.
Examples
Example 1
The following figure shows an example of creating a cascading configuration with -g <group>
and -gs <group> option from the local node (takeover node).
Figure 4 Creating a cascading configuration from the local node
Example 2
The following figure shows an example for creating a suspended journal volume.
On DC1 side:
paircreate -g G1 -gs G2 -FHORC 2 -nocsus -f async <ctgid> -jp <id>
-js <id>
On DC2 side:
paircreate -g G3 -vl -nocsus -f async <ctgid> -jp <id> -js <id>
On DC3 side:
paircreate -g G3 -vr -nocsus -f async <ctgid> -jp <id> -js <id>
Note:
The journal ID for the shared Continuous Access Journal-SVOL must be specified the same
journal ID for SVOL currently. The CTGID for paircreate can be specified the same CT group for
SVOL currently.
