Procedure for removing SAN luns from a system

This will ensure a clean system after lun removal.
Here's what I did:

1) /etc/vx/bin/vxdiskunsetup emcpowerXX

Put the luns back.

2) powermt display dev=all

saw that both paths for the luns were 'dead'

3) powermt remove dev=emcpowerXX

4) devfsadm -C (as Charles suggests below)

5) powercf -q (shows that reverse of adding: path removed messages)

5.5) powermt config

6) vxdctl enable (will show error state for luns removed)

emcpower2s2 auto - - error

7) vxdisk rm emcpowerXXs2

now everything is cleaned!
