Thanks to Jean-marc Vincent, Bluejay Adametz, Andrew Tolme, David
DeWolfe, Phil Sullivan, James Halte, Thierry Faidherbe, Martin Anderson,
and Dr. Thomas Blinn for the replies.
Using a combination of several suggestions, I think I've gotten most of
my drives mapped out. There are still 3 drives that I'm totally unsure
of. This is a production system, so I've got to be darn sure of the
disks I'm going to wipe and I can't take the system down. Some of the
suggestions to locate the disks from the operating system were:
# dd if=/dev/rdisk/dskXYZc of=/dev/null
I was really optimistic about this one, but when I tried to use the
command I get a "device busy" error. I'm thinking that I probably have
to unmount the disk before I do this?
# hwmgr -flash light -dsf/dev/disk/dsk##c
Several replies indicated that the reason this didn't work is because it
only works on physical disk on the scsi bus, not behind an array
controller.
# hwmgr show scsi and use the scsi device number with the locate command
to locate the disk
The scsi device number doesn't seem to correlate with the disk numbers
on the controller.
Suggestion was made to reset the disklabel on the questionable drives,
but I'm not comfortable doing that as I unsure how that will affect the
drive.
As I said, I have most of them identified, but am still wanting a sure
fire ID from system to disk to make absolutely sure I'm hitting the
correct one. I'm going to try unmounting one of the disks that is empty
and then retrying the dd command above, seeing if the busy issue goes
away.
Thanks for everyone's suggestions.

Subject: Trying to locate hard drive from Tru64
Running Tru64 5.1B on ES40 cluster tied to HSG80 controllers to our
storage. I'm trying to locate the physical disks from Tru64. I've
tried using #hwmgr locate -id ### -time 60 (where ### is the HWID
listed on #hwmgr show scsi) and I'm not seeing any indication on any of
the drives. Someone told me to use #hwmgr -flash light -dsf
/dev/disk/dsk##c and that doesn't seem to work either. Does someone
have any ideas what I'm doing wrong or another idea how to locate a
physical disk from the OS?
