This is a NW 6.5 server with a total of 10 volumes (and corresponding pools)
all NSS

_admin
SYS
VOL1
VOL2...
VOL8

Somehow a couple of the volumes have suddenly been renamed as VOL1_1,
VOL2_1, etc. We are quite sure this has not been done by anyone but rather
feel that it is caused by some sort of corruption. Any ideas?
