Netserver LH4 Disk error

[Andre_27]

Good day to all readers of this group and message.
I'm encountering this error with my Netserver which is preventing me from re-installing the OS on the unit.
Seems like the status leds to the right of the Control Panel are suggesting that I have either an impending disk failure or a failed disk. I have diconnected the array controllers to try to figure out which disk is bad by a process of elimination, but to no avail. One thing I've realized is that the disk cage on th eleft of the unit will not allow me to remove any of the drives when I unlock it so I don't know if this is part of the problem.
Any ideas or help is appreciated.
Thanks.

Can you provide more info on what the error is and when you get it? Also, how exactly were you attempting to find a bad disk by disconnecting the array controller? One last thing, if the drive cage lock is stuck, you will have to remove the drive cage in order to remove the locking mechanism.
