HI:
We have connected one IOMEGA JAZ drive on Dec AlphaStation 400/233 under Digital
Unix
v3.2c, we have mounted it with AdvFS:
# df -k
Filesystem 1024-blocks Used Avail Capacity Mounted on
root_domain#root 65536 60688 4848 93% /
/proc 0 0 0 100% /proc

jaz#user3 1025424 542705 471136 54% /user3
but..., when I try to read the disklabel, it replies:
# disklabel /dev/rrz2a
Invalid disk label (label is corrupted, or disk is unlabeled)
# disklabel -r /dev/rrz2a
Disk is unlabeled or, /dev/rrz2a does not start at block 0 of the disk
but if we try to read the label of another disk:
# disklabel -r /dev/rrz0a
# /dev/rrz0a:
type: SCSI
disk: RZ26M
label:

h: 838444 1212416 unused 1024 8192 # (Cyl. 1519*- 2569*)
The drives runs perfectly, as a RZ26M (c partition) disk of digital, is under test
period, but it runs perfectly.
The problem is that in the last test I try to change de type of disk (with RZ26M
disk I
have 20 Mb less than if I configure with Jaz Parameters).
My question is why can't I read or write the label, if the drive is running, the
disk,
theorically, has a label, no?
Thanks

I think that the problem, is solved.
I suppose, that the first time that I format the first disk, in the directory /dev,
was saved /dev/rrz2x (x=a,b,c,d,e,f,g) then the next time that I put other disk, the
computer knows the disklabel, but the label it wasn't wroten to disk, then I made
scu -f /dev/rrz2a, and formats the disk, them mkfdmn, mkfset, and mount it.
The problem may be resolved (as Olle Eriksson suggest) with:
disklabel -rw /dev/rz2a RZ26M (for example)
Then we have wroten the disklabel (as a RZ26M DEC's disk), the next step is made a
disktab for jaz disk (the RZ26M has around 1000Mb, and the jaz has around 1020Mb)
A lot of thanks by his suggestions to:
