In /var/adm/messages I am getting the following errors:

(st4):
Jun 12 03:27:26 server unix: Error for Command: read
Error Level: Fatl
Jun 12 03:27:26 server unix: Requested Block: 63720
Error Block: 6370
Jun 12 03:27:26 server unix: Vendor: HP
Serial Number:62 216
Jun 12 03:27:26 server unix: Sense Key: Media Error
Jun 12 03:27:26 server unix: ASC: 0x11 (unrecovered read
error), ASCQ: 0x0, FRU: 0x0

and in format the drives that show up are:
VAILABLE DISK SELECTIONS:
       0. c0t0d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>

       1. c0t8d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>

       2. c0t9d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>

       3. c0t10d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>

st4 does not show up in the list, could that be another scsi device such as
my tape drive?

Boy, you waited a whole thirty-seven minutes for an answer before reposting
the same question. You're patient... NOT! This is USENET, not 1-800-USA-4-SUN,
and it's going to take a few hours for the message to propagate out, and get a
reply propagated back to you. Chill out, the world isn't going to end if you
don't get this back up immediately.

A quick lesson:

Disks are referred to as "sdX" for "SCSI disk X" in /var/adm/messages. This is
a throwback to the old ways of SunOS 4.X

The /dev/dsk/cWtXdYsZ you see in format and /etc/vfstab is a more descriptive
system:

cW: The SCSI controller. "c0" means SCSI controller zero.
tX: The SCSI ID (target) of the disk. "t1" means target 1.
dY: The SCSI device (LUN) of the disk. "d0" means device zero.
sZ: The partition (slice) on the disk. "s0" means slice zero.

You can translate back and forth between "sdX" and "cWtXdYsZ" monikers by
comparing the device columns of "iostat -x" to "iostat -xn".

Yes, in all likelihood st4 is a SCSI tape drive with SCSI ID 4.
