Package: multipath-tools
Version: 0.4.7-1.1etch1
Our test environment I disconnect one of the FC cable, and reconnect them.
The failed path does not showed again.
Testing environment:
Host: SUN fire x4100 2x dualcore Opteron
6 G of ram
dualport qlogic Fibre channel HBA
lspci:
06:01.0 Fibre Channel: QLogic Corp. QLA2422 Fibre Channel Adapter (rev 02)
06:01.1 Fibre Channel: QLogic Corp. QLA2422 Fibre Channel Adapter (rev 02)
Storage subsystem: NetApp FAS3040c with SATA disks
Software environment:
debian/etch with custom built fresh kernel
~# uname -a

fresh qlogic fc firmware: ISP24xx Firmware Version 4.04.00
Test case:
An 1Tibyte LUN accessed via 4 path:

The lun mounted in /mnt (ext3) and a bonnie++ was running on it.
I disconnected one of the cable:
