Howto: Scrub disks for decommission

Determine how many disks are connected to the system using the format command. It is not necessary to scrub the SAN drives, only the local drives. So from the the format command output make note of the local disk with the highest number.

Use the highest local disk number above as the DISK parameter N in the script below. Create and run the following script to scrub the local disks.

DISKS=N
while [ $DISKS -ge 0 
do
  echo disk>>/tmp/scrub
  echo $DISKS>>/tmp/scrub
  echo defect>>/tmp/scrub
  echo primary>>/tmp/scrub
  echo quit>>/tmp/scrub
  echo analyze>>/tmp/scrub
  echo purge>>/tmp/scrub
  echo quit>>/tmp/scrub
  echo defect>>/tmp/scrub
  echo both>>/tmp/scrub
  echo quit>>/tmp/scrub
  echo analyze>>/tmp/scrub
  echo purge>>/tmp/scrub
  echo quit>>/tmp/scrub
  (( DISKS -+ 1 ))
done
format -f /tmp/scrub
