Hi,

especially in the storage forum you MUST specify your OS. It could be windows, linux, tru64, openVMS, hpux ...

You mentioned "vg" so I assume it's hp-ux.

Is your MSA30 connected to a "normal" SCSI HBA or a smartarray controller?

This is essential for a solution.

If in doubt, post a "ioscan -fn".

If the disk is _NOT_ connected to a smart array controller, see this document:

If the disk is connected to a smart array controller, check the status with

sautil /dev/ciss

(take "x" from your ioscan output), swap the disk and check again. For a mirror drive or a RAID5 / ADG all actions will be done by the controller.
