Cool. I will give that a try too. Also in my wanderings on the web, I have come across the use fstab.order. Also found this on metalink: in note *471256.1* In the /etc/fstab.order file put in all the powerpath device names.
My preference would be to go the udev route, if i can get an example on how to set that specfically for EMC pwerPath devices. If you have, could you please share? Thanks. Will that work too ?
