And FYI: Calling Adaptec technical support on the DPT 3754U2 controllers
was a bust. The customer service agent indicated that "Adaptec does no provide
technical support on obsolete products. You may be able to find some help in the
Adaptec ASK database."
Seagate technical support advised me to download the Seagate SeaTools boot ISO
image but that again only talks to IDE drives. They have a SeaTools Enterprise
edition that runs under Windows or Linux but that requires that your SCSI
disk and controller be installed in a Windows or Linux system. Not an option
for me.
Is it possible to boot a Knoppix "Live" cd or other similar Linux bootable cd so you can run the Seagate Enterprise app on the actual SCO server? If it needs real disk space to install on just use some form of USB drive.
Good suggestion. I moved the SCA cage back to the Adapted 29160 controller
and booted DSL (Damn Small Linux) CD and used firefox to download the SeaTools
enterprise for Linux version and ran it.
The "st -I" shows all the devices on the SCSI bus and identifies the disk
correctly. However, It says "can't get capacity" and "sense error 0/2/0"
"st -t /dev/sgb" command fails with the message "...does not support
DST" Drive Self Test.
I also tried the st -F to low level format one of the drives but that
failed with repeated lines of "formatting ..... 0% completed" and repeated
over and over until I aborted.
The last Seagate enterprise support technician suggested to use the
"zero fill" option to write zeros to the first several sectors but
I was unable to find the zero fill option.
Would 'dd if=/dev/zero of=/dev/sda' or the appropriate SCSI devices, do the job for you? And do you need to recover *any* of this data? A data
root@1[root]# dd if=/dev/zero of=/dev/sga bs=512 count=1
1+0 records in
1+0 records out
root@1[root]#
root@1[root]# dd if=/dev/zero of=/dev/sga bs=512 count=100
dd: /dev/sga: Numerical argument out of domain
root@1[root]#
root@1[root]# fuser /dev/sga
/dev/sga: 581
root@1[root]# ps -ef | grep 581
581 root 512 S st -F /dev/sga
root@1[root]# dd if=/dev/zero of=/dev/sga bs=512 count=1
1+0 records in
1+0 records out
root@1[root]# dd if=/dev/zero of=/dev/sga bs=512 count=2
dd: /dev/sga: Numerical argument out of domain
root@1[root]#
Why not simply say 'dd if=/dev/zero of=/dev/sga'? You want to zero the whole disk if possible, and if you have the time.
When I do, I get the following:
root@0[root]# dd if=/dev/zero of=/dev/sga
dd: /dev/sga: Numerical argument out of domain
root@0[root]#
What does the "Numerical argument out of domain" tell you?
