Go to the Mirroring panel and verify the RPO and status for the volumes to be added to theCG. Select each volume and specify to add to the consistency group (Figure 6-12).Figure 6-12 Volumes and snapshotsThen specify the mirrored consistency group, as shown in Figure 6-13.Figure 6-13 Select CGThe Mirroring panel now shows the consistency group as a group of volumes, all with thesame status for both the master CG (Figure 6-14) and the slave CG (Figure 6-15 onpage 159).Figure 6-14 Master CG status158 IBM XIV Storage System: Copy Services and Migration
Figure 6-15 Slave CG statusThe Consistency Groups panel shows the last_replicated snapshots, and if the sync job iscurrently running there will be a most_recent snapshot, as can be seen in Figure 6-16.Figure 6-16 Mirrored CG: most_recent snapshotRemoving a volume from a mirrored consistency groupWhen removing a volume from a mirrored consistency group, the corresponding peer volumewill be removed from the peer consistency group. Mirroring is retained with the sameconfiguration as the consistency group from which it was removed. All ongoing consistencygroups’ sync jobs keep running.Asynchronous mirroring and snapshot consistency groupsA volume can be in only one consistency group. Because consistency groups can be used forsnapshot and Remote Mirroring, confusion can arise. Define separate and specific CG forsnapshot and Remote Mirroring.XCLI commands for consistency group configurationExample 6-2 illustrates the use of XCLI commands for configuring consistency groups.Example 6-2 XCLI commands for CG configuration-- Activate async Mirrorsmirror_activate vol="HS1_1"mirror_activate vol="HS1_2"mirror_activate vol="HS1_3"Chapter 6.
