[Q]Manually fail DL380 G4 SmartArry 6i disk errors

A disk in a 6-way RAID 5 stirpe is logging fatal read/write errors in
the System event log. The controller has not failed the disk, is there
threshold for it to so or will I have to manually the fail the disk?

Automatic recovery of array now fails with the replacement disk. SCSI
backplane has been also been swapped out. ADU is reporting 4 of 6 disks
with errors but again the controller has not failed any of them.

Next swap is the 6i controller.

Motherboard swap did not have the desired effect. Automatic recovery
stills fails due errors on disk 1.

Needless to say I am bit concerned about the ability of the 6i
controller to detect errors and fail drives.

The only errors logged thus far have been from Win 2k Server during
boot. Initially only disk 5 reported errors until swapped out for
recovery which to date has fails. Errors are now reported on disk 1.
