removing partition

[Francis Flan]

Hi,

Take a look at the o/p of an ioscan:
disk 5 0/3/0/0/0/0.5.0.16.0.0.2 sdisk CLAIMED DEVICE COMPAQ HSV111 (C)COMPAQ
/dev/dsk/c1t0d5 /dev/dsk/c1t0d5s2 /dev/rdsk/c1t0d5 /dev/rdsk/c1t0d5s2
/dev/dsk/c1t0d5s1 /dev/dsk/ocr1 /dev/rdsk/c1t0d5s1 /dev/rdsk/ocr1

I used mksf to create /dev/[r]dsk/ocr1 path name and idisk to partition the disk.
Can I undo this without destroying all partition information?
(i was experimenting!)

Not sure what you really want to do.

Thread title is "removing partition", but you say "... without destroying all partition information ..."

What do you want to remove?

Torsten,sorry youre right, i wasnt very clear.

Id like to remove the dev/rdsk/c1t0d5s2 partition and also remove the device path /dev/rdsk/ocr1
Is this possible or do I have to destroy all parttiion info?
thanks for your help

I hope I understand it right now.

See
http://docs.hp.com/en/B2355-60105/idisk.1M.html

examples:

Destroy all partition information on the disk:

idisk -R /dev/rdsk/c1t0d5
