SAN Partition disapeared

hi all

i am not very experience in Red Hat linux EL 4, i have 2 servers connected with a SAN.(Fujitsu primergy server RX 300s4,fujitsu FiberCat SX SAN Device

there are two shared partitions on san (900gb ,300gb), from last 6 months these 2 servers were functioning fine , but yesterdays i faced a problem, i found that server2 is not showing the partitions on the shared drives 900GB , and nothing can be access because it was totally invisible , i tried my best to find the cause y this partition disappeared,
Please NOTE server1 is still showing 900gb shared storage and showing normal behavior, these servers were not clustered.

SAN Console showing all physical volumes 100% functioning.

Can any one help me what happened to server2 ,not showing shared storage.

I presume you have unmounted on server 1 and rebooted server 2? I would cycle the power as well. strange things can be held over. I am informed by those who claim to know that reboots, hard resets, and cycling power all have slightly different effects. Otherwise schedule some overtime at 6:00 on a sunday morning, and go at them, swapping components into one to see if you can transfer the fault.
