Re: wipe out the data

About the best you can do for free is something like this:

Start with all the non-vg00 disks (you can umount the filesystems if you like):

DISKS="/dev/rdsk/c5t1d0 /dev/rdsk/c6t4d0"
for DISK in ${DISKS}
do
dd if=/dev/zero bs=256k of=${DISK}
done

then repeat for the disk(s) that make up vg00.
If it ain't broke, I can fix that.

Sorry how to wipe out vg00 since this is a OS volume.

Same answer. It will start and load dd. Once in memory nothing more is needed and it will continue to blast data.
If it ain't broke, I can fix that.

Hi,

there is a command

#mediainit

use this on ALL the disks which was part of the VG.

This is like LOW LEVEL formatting.

Siva.
