Can be like this one?
#vgcreate -f /dev/vg01 /dev/dsk/c20t0d0 /dev/dsk/c20t0d1 /dev/dsk/c20t0d2 /dev/dsk/c20t0d3

hi WS,

I think the step is run the 'vgcreate' 1st and then 'vgextend'.

# vgcreate -f /dev/vg01 /dev/dsk/c20t0d0
# vgextend /dev/vg01 /dev/dsk/c20t0d1 /dev/dsk/c20t0d2 /dev/dsk/c20t0d3

to verify

# vgdisplay -v vg01

it should show something like the following at the end..

--- Physical volumes ---
PV Name /dev/dsk/c20t0d0
PV Name /dev/dsk/c20t0d1 Alternate Link
PV Name /dev/dsk/c20t0d2 Alternate Link
PV Name /dev/dsk/c20t0d3 Alternate Link

GOOD LUCK!!

I see a different setup based on this information.

There are 4 LUNs, LUN0, 1, 2 and 3.

The hardware path (255/255/0/0.0) indicates to me you are using autopath - not PVLINKS.


The pathes you mentioned

/dev/dsk/c20t0d0
/dev/dsk/c20t0d1
/dev/dsk/c20t0d2
/dev/dsk/c20t0d3

Are not alternate pathes to the same LUN but really 4 different LUNs.
