You can check the volume by using show volumes command on management server and also check the volume state from the /opt/pang/log/pang.log on cache server(ce-x).

 

This is the example from management server using show volumes.

console# show volumes
Licensed volumes : 24
Volume name          State                Owner
/mnt/vol1            mounted              ce-1
/mnt/vol2            mounted              ce-1
/mnt/vol3            mounted              ce-1

 

This is the example from ce-13 pang.log,
