This server was setup more than 5 years ago when I wasn't even here, but if
you look at the metastat d2 output from my initial post, that tells you hou
it was originally setup. As far as the dsk maintenance, I called Sun and
they told me the disk needed to be replace and went ahead and sent me a new
one, but have no been very helpfull afer that.

Hee's some info on the three disk that are currently involved.

# ls -l /dev/dsk/c1t0d0s0 /dev/dsk/c1t2d0s0 /dev/dsk/c2t2d0s0
lrwxrwxrwx 1 root root 50 Mar 27 2003 /dev/dsk/c1t0d0s0 ->
../../devices/sbus@3,0/SUNW,fas@3,8800000/sd@0,0:a

# eeprom nvramrc
nvramrc: data not available.

So, I could execute the following eeprom command to reset the boot disk.

"nvramrc=devalias rootdisk /sbus@3,0/SUNW,fas@3,8800000/disk@2,0 rootmirror
/sbus@3,0/SUNW,fas@0,8800000/disk@2,0
