Kernel 2.4.21-15.0.3.ELsmp running RHEL 3.0/U2. Using card QLogic 2340. The qla2300.o does not recognize HP Ultrium LTO drives in the zone.

I ended up buying a different HBA to resolve this issue.
For the record: There seems to be an incompatibility between the 6.07.02-RH2 driver and certain FC switches. This problem prevents some devices from being discovered. The following messages in the log are indicative of the problem: scsi(2) qla2x00_isr MBA_PORT_UPDATE ignored In at least one case the v7 QLogic driver in RHEL 3 U3 solves this problem.
