Adding the repaired storage system to cluster, Rebuilding volume data – HP LeftHand P4000 SAN Solutions User Manual
Page 255
If necessary, ensure that after the repair you have the appropriate configuration of managers. If
there was a manager running on the storage system before you began the repair process, you
may start a manager on the repaired storage system as necessary to finish with the correct number
of managers in the management group.
If you added a virtual manager to the management group, you must first delete the virtual manager
before you can start a regular manager.
1.
Right-click the virtual manager, and select Stop Virtual Manager.
2.
Right-click the virtual manager, and select Delete Virtual Manager.
3.
Right-click the storage system, and select Start Manager.
Adding the repaired storage system to cluster
1.
After the initialization completes, right-click the cluster, and select Edit Cluster. The list of the
storage systems in the cluster should include the ghost IP address.
Add the repaired storage system to the cluster in the spot held by the ghost IP address. See
.
2.
Select the ghost storage system (the IP address in the list) and click Exchange System.
3.
In the Exchange Storage System window, select the repaired storage system to exchange for
the ghost storage system and then click OK.
4.
To ensure that only the repaired storage system goes through the rebuild, verify that the order
of the storage systems in the cluster list matches the original order and then click OK.
The storage system returns to its original position in the cluster and volumes in the cluster
proceed to resynchronize.
NOTE:
If you do not arrange the storage systems to match their original order, the data in
the cluster is rebuilt across all the storage systems instead of just the repaired storage system.
This total data rebuild takes longer to complete and increases the chance of a second failure
during this period.

Rebuilding volume data
After the storage system is successfully added back to the cluster, the adjacent storage systems
start rebuilding data on the repaired storage system. To verify progress:
1.
Select the cluster, and select the Disk Usage tab.
2.
Verify that the disk usage on the repaired storage system starts increasing.
3.
Verify that the status of the volumes and snapshots is Restriping.
Depending on the usage, it may take anywhere from a few hours to a day for the data to be
rebuilt on the repaired storage system.
