PERC 4/SC Controller 0, Array Disk 0:1 Sense Key = 5, Sense Code = 21, Sense Qualifier = 0. If this disk is part of a redundant virtual disk, select the 'Offline' option and then replace the disk. Then configure a hot spare and it will start the rebuild automatically. If this disk is a hot spare, select the 'Prepare to Remove' option and then replace the disk. If this disk is part of a non-redundant disk, you should back-up your data immediately. If the disk fails, you will not be able to recover the data.
Tried to run "dell-pediags-win32-22.214.171.124-A01.exe" and it hung (18hrs to reach only 36%). Controller tested good though.
Trying to run "Dell_DSET_1.3.2.exe" and it appears to be hung (or very slow) also.
I know this server hasnt had any firmware or Controller driver updates in 3 years. I probably just answered my own question but need to hear what the pros think.
I am also in contact with tech support on the matter.
