Unfortunately there's very little technical documentation. This is one
of HP's 'low end' SANs. I'll see if HP support has anything to say
about it.
I'm not really having luck with be2iscsi, now that i've managed to get
it to login to the target, I'm getting the following kernel panic
after around 15-20 minutes of the machine being up and logged in
(copied from the console). Any ideas? I am using multipath.
