The following is the patch to include a hardware definition for
Compellent's SAN. This is my first patch so hopefully I did everything
correctly. The definition in config form is below, if for some reason my
code doesn't match that, please inform me.

device {
vendor "COMPELNT"
product "Compellent Vol"
path_grouping_policy multibus
path_checker tur
checker tur
failback immediate
no_path_retry queue
}

That is bogus. There are no 'checker' field in the .conf file. Hopefully
that isn't in your product release notes.

I know, but that's when dumps out when you do a "show config" So
obviously my statement was slightly redundant. But I just wanted to make
sure it was clear what settings I wanted.
