Volume T49152 on diag209-v1a changed from 6257335A-30303142(active=50020F23- 00006DFA,passive=) to 6257335A-30303142(active=50020F23- 00006DFA,passive=50020F23-0000725B)

INFORMATION:

This event occurs when the virtualization engine has detected a change in status for a Multipath Drive or VLUN, usually meaning a pathing problem to a Sun StorEdge T3+ array controller for changes in Active/Passive paths.

1.Check Sun StorEdge T3+ array for current LUN ownership. (‘port listmap‘)

2.Use ‘mpdrive failback‘ if needed to fail LUNs back to correct the controller if needed
