Re: SAN help

Thanks for the Link Ray.

One thing I am confused is... "failover manual" means whenever there is a link failure this will case the host to be rebooted?


Paras.

I'm not familiar with this SAN, so can't suggest to you a better
device configuration snippet.

Google may help you out: search for your device type and
"multipath.conf".  Alternately, if your vendor supports RHEL5 (I'm sure
they do), you could contact them and ask them to provide you with a
known good configuration.

Actually, a quick search yields this:

Which seems to have what you need (verify of course).
