I'm having a problem relabeling a disk. It's a Seagate ST15150W that
was used on an Alpha Debian linux system. I don't seem to be able
to get the disklabel program to write anything new. Partitions a and
c are not at offset 0.
How can I get control back of this thing? Any way of writing to this
thing raw? It's at bus 0, lun 0, target 0.
This is tu5.1
Here are some cut/paste details:
The disk label includes:
3 partitions:
# size offset fstype [fsize bsize cpg] # NOTE: values not exact
a: 5665464 2268 resrvd8 # (Cyl. 1 - 2498)
b: 1589868 5667732 resrvd8 # (Cyl. 2499 - 3199)
c: 1131732 7257600 swap # (Cyl. 3200 - 3698)
When trying to do any normal editing of that disklabel:
"/tmp/EdDk.aaaaVca" 24 lines, 668 characters
write new label? [y]: y
partition c: partition extends past end of unit
re-edit the label? [y]: n
So I cannot change the label to add or modify a partition with offset=0.
Also:
# disklabel -z dsk10c
Disk is unlabeled or, /dev/rdisk/dsk10c is not in block 0 of the disk
And:
# disklabel -sF dsk10c unused
The disklabel for /dev/rdisk/dsk10c could not be updated.
Other attempts:
I'm not real well versed in the scu program. I tried
running scu and writing raw data to the disk, hoping that
would clear things. However, I'm not running scu right to
do this:
# scu -c /dev/cam
scu> set nexus bus 0 lun 0 target 0
Device: ST15150W, Bus: 0, Target: 0, Lun: 0, Type: Direct Access
scu> write media starting 0 limit 1m bs 10k
scu: Mounted file system check cannot be performed using '[0/0/0]' (ST15150W).
Any advice would be appriciated.
