Can someone tell me why I am getting the below errors when I run multipath or multipath -ll?

Your multipath.conf file is messed up.

Yep when upgrading from RHEL 5.7 to RHEL 5.9 when I rebooted the server it couldn't connect to the SAN so I had to lay down the old multipath.conf file for it to connect to the SAN so I assume there were many changes in /etc/multipath.conf from 5.7 to 5.9

I doubt the format changed. Are you sure you still have all the dm modules loaded? Are you sure the file wasn't changed?

I just found a doc that said prio_callout has been changed to prio and the “/bin/true” value was removed because it was causing problems when root was on a multipathed disk.
So I just had to pick through it and update the file with the newer/correct values.

The polling_interval option cannot be applied per-device and as such, is only valid in the defaults block of /etc/multipath.conf

a question???
WHY?
why not upgrade the the current in the older rhel5 series
RHEL 5.11
