Clear data off disks

David Pscheid — Tue, 25 Sep 2001 19:26:15 GMT

We have an old K200 system running HPUX 10.20 and I have been instructed to delete all data on all of the disks. I looked for a format command to just overlay everything but couldn't find anything. What's my easiest way to clear the disk so we can scrap the system.

Thanks

for i in /dev/rdsk/*
do
dd if=/dev/null of=$i bs=64k
done

should do the trick... You probably want to exclude the root drive, and save that for last.

Hi David,

Do a vgremove for all the VG's you have on the system. once done do a pvcreate on all the disks using "pvcreate -f /dev/rdsk/c?t?d?".

That should do the trick.

Hope this helps.

thanks

P.S. : Vincent if use the script as mentioned by you it will take into account the root disk also.

Just found this link, so thought I would put it in the forums for people to find as an alternative solution.

Null points please. Ian
