A full 'ioscan' would be helpful.  However, it appears that whatever is at 0/0/0/5/0/0/1.2.71 has failed because all disks on that paith are inaccessable.

 

The problem could be a FC card, cable, FC port on a switch, controller on the array.  You  need ot determine what exactly has failed.

It could also be that the LUN on the Clariion has trespassed.

But it could also be that someone has simply removed the LUN on the storage side and forgot to inform you?

Missing some filesystems to on that system? Or wasn't it in use?
