emcpower/vxvm/did device mappings

Every now and again I need to work out mappings between emcpower devices, vxdisk list output and Sun Cluster did devices. Today I got a bit bored with trying to work it out manually again, so I wrote this script.

It could maybe be more elegant but I couldn't work out a way of avoiding using the temporary file. It works, anyway, so here goes;


for i in `vxdisk list | grep emcpower | nawk '{print $1}'`
do
echo
inq 2>/dev/null | grep `inq 2>/dev/null | grep $i | nawk '{print $5}'` > /tmp/inqout
j=`head -1 /tmp/inqout | nawk '{print $1}' | sed 's/\/dev\/rdsk\/c.//' | sed 's/s2//'`
echo VxVM device:
echo $i
echo did device:
scdidadm -L | grep $j
echo EMC devices:
cat /tmp/inqout
rm /tmp/inqout
done

Where it says "metasync" though, it is OK to do a "metasync -r" at this point which saves a very lengthy wait for mirrors to resync.
