I have an F820, 6.4.2P6, with dual port FC card that's getting a lot of scsi timeout msgs on the 7b port. The scsi timeouts spans all disk shelves on the 7b loop. All other loop is fine. These started when I moved the 18GB FC9 shelves from a F880c to the F820.

Working the tech support, I replaced a couple of the LRC, replaced two shelf cable interconect, recheck all the cables, replaced FC card slot 7, remove/reinsert all the drives, and ran fcal check which passed all fcal tests. The core file result indicated to bug #98110 but upgraded to v6.4.2P6 did not resolve these error msgs. The filer panic a few times before running v6.4.1 that's why tech support recommends upgraded to v6.4.2P6.

Right now I disconnected the second loop 7b. Any ideas?

Slot: 7b Description: Fibre Channel Host Adapter 7b (Dual-channel, QLogic 2200A rev. 5) Firmware Rev: 2.1.32 PCI Bus Width: 64-bit PCI Clock Speed: 33 MHz
