Environment

Novell Open Enterprise Server (Linux based)
Novell SUSE Linux Enterprise Server 10
Novell SUSE Linux Enterprise Server 9
Native Multipath I/O (MPIO)
HP StorageWorks 1000/1500 Modular Smart Array (MSA1000/MSA1500)

Situation

Multiple paths are showing up as faulty or ghost. There is an error message ERROR: device not found in pathvec in the multipath -v2 output.

Resolution

Update the MSA1000 firmware. There is an issue with older firmware that will make paths faulty if active and passive devices are attached to the SAN.
