System cannot see logical drives on RAID 4si card (jbod)

I rebooted and afterward the system cannot see any drives in the RAID.
vg01, vg02 and vg03 should be there.
vgdisplay -vg01 gives:
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "vg01".

vgchange -a y /dev/vg01 gives:
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c4t0d0":
A component of the path of the physical volume does not exist.
vgchange: Warning: couldn't query physical volume "/dev/dsk/c4t0d0":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "/dev/vg01":
Quorum not present, or some physical volume(s) are missing.

ll /dev/vg01 gives:
brw-r----- 1 bin sys 31 0x040000 Jul 31 2002 /dev/dsk/c4t0d0

The three logical volumes don't show up at all on ioscan also.

Please help.
Points will be awarded..
Thanks,

Re: System cannot see logical drives on RAID 4si card (jbod)

While ioscan doesn't see the logical drives irdisplay states (for logical drive (0)):
RAID Device Hardware Path: 0/10/0/1.0.0.0 (Logical Drive 0)
RAID Device Driver: sdisk (Class disk Instance 4)
RAID Device Files: /dev/[r]dsk/c4t0d0
RAID Device State: CLAIMED
RAID Level: RAID5
Size: 5239808 Kbytes

'ioscan -fnd sdisk' only shows the two internal drives that make up vg0

Hope this might help....
