To Failback the Virtualization Engine

In the event of a Sun StorEdge T3+ array LUN failover, the virtualization engine will

route all I/O through the failover port on the Sun StorEdge T3+ array. After you

isolate and check the cause of the failover, the virtualization engine continues to

send I/O through the failover path. To restore the I/O to the primary path and fail

the LUN back to its original controller, use the following procedure:

1. Verify that the T3+ array active path needs to be restored by viewing a live

snapshot of the virtualization engine map, as shown in “Viewing the

Virtualization Engine Map” on page 118.

If there has been a failover, the Multipath Drive Summary will show the same Sun

StorEdge T3+ array active path WWN for all LUNs associated with one Sun

StorEdge T3+ array, as shown in

CODE EXAMPLE 9-3.

CODE EXAMPLE 9-3 Multipath Drive Summary

2. If the Sun StorEdge T3+ array LUNS have failed over, run the command found in

CODE EXAMPLE 9-5 for that specific Sun StorEdge T3+ array.

Note – The Sun StorEdge T3+ array name is the same as the disk pool name—but

with the last digit (equal to the Sun StorEdge T3+ array LUN number) removed, as

shown in

CODE EXAMPLE 9-4.

For example, the LUNs in disk pools t3b00 and t3b01 are named t3b0 on the Sun

StorEdge T3+ array device.
