The following tables list the GAD configuration operations, pair operations, setting operations, and display operations and provide the corresponding CCI commands and options.

Select external path groups raidcom add external_grp
Create external volumes raidcom add ldev
Add quorum disks raidcom modify ldev
Create virtual storage machines (resource groups) raidcom add resource
Reserve host group IDs raidcom add resource
Delete virtual LDEV IDs (release reserve attribute) raidcom unmap resource
Reserve LDEV IDs raidcom add resource
Assign GAD reserve attribute raidcom map resource
Create host groups raidcom add host_grp

Table. CCI commands for GAD pair operations
Operation Parameter CCI command Option
Create GAD pairs Fence Level paircreate -f never
Copy Pace paircreate -c <size>
No initial copy paircreate -nocopy
Registration to a consistency group paircreate -fg never <CTG ID>
ALUA mode change raidcom modify ldev -alua{enable | disable}
I/O preference mode when remote path failed paircreate -pr pvol
Suspend pairs P-VOL specification pairsplit -r
S-VOL specification pairsplit -RS
Suspend consistency groups None pairsplit None3
Resync pairs P-VOL specification pairresync None
S-VOL specification pairresync -swaps
Copy Pace pairresync -c <size>
Registration to a consistency group2 pairresync -fg never <CTG ID>
ALUA mode change raidcom modify ldev -alua{enable | disable}
I/O preference mode when remote path failed pairresync -pr{pvol | disable}
Resync consistency groups None pairresync None1
ALUA mode change raidcom modify ldev -alua{enable | disable}
Delete pairs P-VOL specification pairsplit -S

S-VOL specification

pairsplit -R
Delete pairs forcibly3 P-VOL specification (Enable is specified for Volume Access.) pairsplit -SFV
P-VOL specification (Disable is specified for Volume Access.) pairsplit -SF
S-VOL specification (Enable is specified for Volume Access.) pairsplit -RFV
S-VOL specification (Disable is specified for Volume Access.) pairsplit -RF

Notes:

  1. When you suspend or resynchronize pairs registered to a consistency group without specifying any option, the pairs are suspended or resynchronized by the consistency group.
  2. When you resynchronize pairs not registered to a consistency group, you can register the pairs to a consistency group.
  3. Delete pairs forcibly when the I/O mode of both P-VOL and S-VOL is Block.
