Hi
I want to have multipath manage only the CLARiiON LUN that I boot from (LUN 0). So I know that I can specify the following in /etc/multipath.conf:
blacklist {
wwid *
}
blacklist_exceptions {
wwid nnnnnnnnnn
}
The wwid value is different for every CLARiiON LUN. So, if I want to automate the process of adding the 'wwid' value to the blacklist, what utility can I use to specify a LUN number, and find the WWN of the LUN?
Thanks!
