We are using the following:

HP ML370 G3
8GB memory
Qlogic QL2340 HBA X 2
Qlogic/EMC driver 6.80.07
EMC Powerpath
EMC CX500 Storage Array
McData 24 port switches
Novell Netware 6.5 SP3

When the server boots it takes 10 minutes or more "scanning for devices
and partitions". If we remove either of the HBAs then it takes about
60 seconds to get past this point. We have tried different slots on
different buses, same result. After checking other posts I removed the
storage group and re-added it, this did nothing.

We have 6 other servers, 4 Dell 2850s, 1 Dell 2650 and 1 HP ML370 G4
with the same software and drivers loaded. All HBAs came in the same
batch. These servers are not showing any issues at all.
