We use two Sun X4270 for cluster pair and the shared storage is CX4-80.
The cluster software is VCS 5.0 MP3.

We found a problem when switchover from one node to another node.

Normally, the volume manager deport the disk group and import the disk group.
Sometime can't import the disk group and all volume manager command no response.

Then I try to use powermt display to check the storage path status. It also no response and output until Cont-C

Normal output
