We have a bunch of HP Proliant DL360P servers, running SLES 11 SP3 (and OES 11 SP2). These machines have a internal RAID controller (B120i), which uses a driver from HP named "hpvsa".

We also use a few Lenovo ix4-300d storages linked to these servers, working as an iSCSI source, so we can have a Novell Cluster on our branch offices.

We've seen that when, for any reason, the servers loose contact with the iSCSI host (the storage), system throws a kernel panic, related to the hpvsa driver.

Does anyone have seen this before? This situation is causing a lot of trouble, specially in one of the branches (which, for some reason, have its' switches reset nightly --- so I have to reset both servers almost every morning).
