Deactivation on the masterTo deactivate a mirror select Deactivate, as shown in Figure 6-20.Figure 6-20 Mirror CG deactivateThe activation state changes to inactive, as shown in Figure 6-21. Subsequently, thereplication pauses (and records where it paused). Upon activation, the replication resumes.Note that an ongoing sync job resumes upon activation. No new sync job will be created untilthe next interval.Figure 6-21 Mirror CG inactiveDeactivation on the slaveDeactivation is not available, regardless of the state of the mirror. However, the peer role canbe changed to master, which sets the status to inactive.Note that for consistency group mirroring, deactivation pauses all running sync jobspertaining to the consistency group.164 IBM XIV Storage System: Copy Services and Migration
Using XCLI commands for deactivation and activationExample 6-4 shows XCLI commands for CG deactivation and activation.Example 6-4 XCLI commands for CG deactivation and activation-- Deactivate Mirrored CGmirror_deactivate cg="HS_Pool1_CG"-- Activate Mirrored CGmirror_activate cg="HS_Pool1_CG"DeletionWhen a mirror pair (volume pairs or a consistency group) is inactive, the mirror relationshipcan be deleted. When the mirror is deleted, the XIV forgets everything about the mirror. If youwant to set up the mirror again, the XIV must do an initial copy again from the source to thetarget volume.When the mirror is part of a consistency group the mirror first must be removed from themirrored CG and the last_replicated CG for the master and the slave must be disbanded. Thissnapshot CG is recreated with only the current volumes after the next interval completes. Thelast_replicated snapshots for the mirror can now be deleted, allowing a new mirror to becreated.Note that when the mirror is deleted, the slave volume becomes a normal volume again, butthe volume is locked, which means that it is write protected. To enable writing to the volumego to the Volumes list panel, select the volume, right-click it, and select Unlock.The slave volume must also be formatted before it can be part of a new mirror. Formattingalso requires all snapshots of that volume to be deleted.XCLI commands for mirror deletionExample 6-5 illustrates the use of XCLI commands for mirror deletion.Example 6-5 XCLI commands for mirror deletion-- delete Mirrorcg_remove_vol vol="HS2_3"mirror_deactivate vol="HS2_3"mirror_delete vol="HS2_3"-- Format slave volumesnap_group_disband snap_group="last-replicated-HS_Pool2_CG"snapshot_delete snapshot="last-replicated-HS2_3"vol_unlock vol="HS2_3"vol_format vol="HS2_3"-- Delete snapshots on Mastersnap_group_disband snap_group="last-replicated-HS_Pool2_CG"snapshot_delete snapshot="last-replicated-HS2_3"Chapter 6.
