How clear disk with partitions on HP-UX v2?

When you say "clear" I am assuming you wish to erase all forms of data on these disks ?

If so:
-bulk eraser
-mediainit ( takes forever )
-dd a pile of jibberish onto the disk (also takes forever but not quite )
-some commercial shredder software

yes
I want to remove (delete) partitions:
/dev/dsk/c3t12d0s1
/dev/dsk/c3t12d0s2
/dev/dsk/c3t12d0s3

In that case. How about the same utility that was used to create it.

man idisk

idisk -R is probably the option you want.

You can use idisk with -R option as well - http://docs.hp.com/en/B3921-90010/idisk.1M.html

Hi:

Your response was "dont work". Did you enable the write-back? viz.

# idisk -Rw /dev/rdsk/cXtYdz

Regards!

Use rmsf command

for eg:-

rmsf /dev/dsk/c3t12d0s1
rmsf /dev/dsk/c3t12d0s2
rmsf /dev/dsk/c3t12d0s3
