Hi All,

I have A3500FC attached to E3500 server. OS is Solaris 2.6 and RM 6.22.01.

Yesterday Suddenly we encounter problem like 10 hard disks are failed and
Amber LED was ON. and below is healthchk -a out put.

I took power cycle the server and storage, but no use, then I tried failed
disk revive at only one time and reconstructed raid sets and data has been
recovered. After that I applied all below patches and upgraded Firmware of
A3500FC.
