My original question was:

: I have an HP SCSI (single ended) drive, previously was connected to
: an HP machine, giving some problem when I try to add it to Sun
: SPARCstation 2. The bootup process recognize the drive and give an
: error: currupted label. The format command does not even see the drive
: and returns: Disk not found.

: The SPARCstation 2 is running SunOS 4.1.3.

We decided to upgrade SPARCstation 2 to Solaris 2.4 and the installation
program was able to format the disk. I am including the response I
received. My many thanks to following people:

Look at the jumper setting on the dirve, all Sun hard disk require
either receive a signal before spinning up or spinning up when power on.
Something for you to look into.

You need to get a /etc/format.dat entry for the disk,
both the physical description section and the partitioning
Then while in format, re-label it.

you have to boot from the installation CD,
then startup the Miniroot from SunOS 4.1.3
start the format Program and choose "backup"
from the format Menu. That's all.

Are you sure you have installed it on the right SCSI port?
Run probe-scsi at the "ok" prompt, and see if it's correctly mapped.

        Assuming that the HP drive is an external drive, have you
        changed the SCSI address to be different than that of
        any SCSI drives you may have on the Sun?
