Hi List,

We frequently have problems connecting RHEL to our HP SAN.

I already tried with support but got different answers any time I asked.
:-(

So, what are your experiences? We want to start a new server with the
followin setup:

* HP DL380 Server
* 2 QL2400 HBAs (HP branded)
* HP EVA8100

What driver should I use? There is the built-in from RedHat, one from
QLogic and one from HP. Either of them got us into trouble, so what do
you suggest to use?

Or did you get better results by using different HBAs? We would even buy
new ones, if that could fix our problems.

To make it even worse, we don't have reproducable errors, but all kinds
of problems. HBAs don't see presented disks (sometimes all of them,
sometimes just some of them), Failover won't work, OS sees disks
multiple times (one for each path, one for each controller - it
differs), OS won't boot because it tells us, the HBAs are just speaking
rubbish, etc.

So, could you give us some of your experiences?

Thanks a lot,
Thomas
