I'm having some trouble installing a new disk for our Digital PWS 500au.
The disk in question goes into an 80-pin slot in an Andataco tower which
is attached via SCSI directly to the CPU. The tower presently has
another 21Gb Seagate in it which runs fine. The new disk is a Quantum
QM318200-SCA, an 18.2 Gb SCSI. We're running Digital Unix 4.0c.
So here's my sad installation tale:
!. Shutdown the system and power the CPU and disktower down. Stuff the
new disk into a free slot and power up the tower and then the CPU up. So
far so good.
2. Now run: # /sbin/scu show edt
and get:
device QM318000TD-SCA
bus: 2
target: 3
So using the rule: bus*8 + target = 2*8 + 3 = 19
Which implies the new disk is rz19
3. Next, # /dev/MAKEDEV rz19
4. Rebuild kernal, doconfig -e MY_HOST_NAME
and moving the new kernal to the acitve kernal location /vmunix
and reboot, # /sbin/reboot
so far, so good.
5. Next, I go the the Disk Configuration widget within the CDE and set
the disk
up as one 18Gb partition (c) using a 4.2 BSD file system. [This is
the same setup
I've got for the existing 21Gb Seagate.]
6. Here's where I get stuck. Upon commiting to the disk setup, I get an
error message
stating that, "disklabel failed to write label"
7. Here is the output of: # disklabel -p rz19c
type: SCSI
disk: QM318000
label:
flags: dynamic_geometry
bytes/sector: 512
sectors/track: 228
tracks/cylinder: 20
sectors/cylinder: 4560

8 partitions:
# size offset fstype [fsize bsize cpg]

28*)

c: 35566499 0 unused 0 0 # (Cyl. 0 -

d: 0 0 unused 0 0 # (Cyl. 0 -

e: 0 0 unused 0 0 # (Cyl. 0 -

f: 0 0 unused 0 0 # (Cyl. 0 -

g: 17586641 393216 unused 0 0 # (Cyl. 86*-
3942*)
h: 17586642 17979857 unused 0 0 # (Cyl. 3942*-
7799*)
8. This disk appears to be too new to appear in my disktab table. I
tried to get
this info using: # disklabel -rw /dev/rrz19c unknown
But the result was: "write: I/O error"
I also tried: # newfs /dev/rrz19c /dev/rrz19c
But the result was: Error: the disklabel for /dev/rrz19c does not
exist
or it is corrupted
9. The disktab entries in Digital Unix 4.0d are identical to the ones I
have
in 4.0c, so upgrading to the more recent OS doesn't appear to be the
fix here.
10. Soooo ... at this point it appears the system can see the new disk
on
the SCSI chain, but cannot put a "disklabel" on it, which is
apparently
a prerequisite for going any further with the installation.
My questions are:
A. Is this particular Quantum disk compatible with Digital Unix 4.0c?
B. If it is compatible, what am I doing wrong, and what should I do to
get this puppy to work?
C. If this disk will not work, why not, and is there a comparable
18Gb disk that does work that I should exchange the my present
disk for?
Thanks muchly,
- Jim
