I have checked the logs on the FC switch and the HBAs
and i dont see any event which suggest both paths failed at once. Even
the errors i captured out of dmesg show that one of the physical disks
that makes up dm-0 had 'end_request: I/O errors' while the other did not
have any such error.
At this point iam wondering how paths 8:32 and 8:48 failed together -
considering both paths are through two different FC switches. Any
suggestions on this ?
Additionaly, I have looked at the mailing list archives & annotated conf
files and found two options a) failback and b) no_path_retry. What would
be the best recommended values for these on a dual controller setup like
It would also be helpful if someone could share infotrend specific
settings multipath settings.
