rmdev command

AIX has a great command: rmdev.

Very useful to remove lun or disks before detach them. Reading the "Online storage guide" i made a script to do somethink like:

#!/bin/bash

# multipath -ll $1 not always works!!
WWID=`multipath -ll | grep -e "^$1 " | awk '{ print $2 }' | tr -d \( | tr -d \)`
multipath -ll $WWID > /tmp/"$1".txt

echo multipath -f $1
echo
cat /tmp/"$1".txt | grep active | grep ready | awk '{ print $3 }' | while read I;do echo blockdev --flushbufs /dev/$I;done
echo
cat /tmp/"$1".txt | grep active | grep ready | awk '{ print $3 }' | while read I;do echo echo 1 \> /sys/block/$I/device/delete ;done
echo
echo vi /etc/multipath.conf
echo
echo /etc/init.d/multipathd restart

It's very stupid, only shows command to execute but it simplify my life when I work with many luns with many path.

AIX "rmdev -dl" command is much better.

The same problem is present when we have to resize a lun.

I think some utilities to do basic operations on SAN lun's should be provided with an ENTERPRISE system like RHEL.
