Root disk delete?

[James M. Dunn]

What is the best way to erase a root disk so it cant be used anymore?

Thanks

Some prefer doing a dd to the disk because a mediainit takes to long but they both will erase your root disk:

James,

use any of the following
1. pvcreate -f
2. dd if=/dev/zero of=/dev/rdsk/ bs=1024k
3. rm -rf /etc, /stand, /usr

Enjoy..!!!

Re-install the OS.

After that, just do a rm -rf /

When you say "so it can't be used any more" do you mean that literally? If so, you could do what we do: take it out of the server/workstation and bang it on the corner of an overhead cabinet. It definitely can't be used any more then!

Hi James,

If you want the data can't be read by any program. Then you need to write the disk 3 times completly.
If you just want to destroy the disk. Get it trhough a shredder.

I've used mediainit without any problems but some folks say it can cause problems.

mediainit -v /dev/rdsk/c?t?d?

However, this is what I do:

rm -rf /stand/* /etc/*
then I do....
for x in `ls /dev/rdsk`
do
dd if=/dev/zero of=/dev/rdsk/${x} bs=1024k &
done

Run this to watch the fun...

while true
do
date ; ps -ef | grep zero | grep -v grep | awk '{print $10}' | sort ; echo "\n\n" ; sleep 30
done

The reboot and shutdown commands are now gone so you'll need to get on the GSP or physically get to the server to down it the rest of the way.

Mark & Mark,

Funny :)

All good answers. I will be trading the servers in and dont want to destroy the hardware just the data.

Thanks!

Strangely enough, it wasn't a joke - that's really what we do if we don't want a disc to be used again.
