Hello,   If that's the error message you receive when you install the replacement drive, I would think that drive is defective.    Re: Firmware.  There's no way to upgrade the firmware to make a drive EQL compatible.  For example a Dell OEM drive designated for Compellent storage, won't work in an EQL array.  (and vice versa)  Re: CLI command.  It won't help in this case.  At the Group CLI type:   GrpName>member select drive select clear-label  Regards,   Don 
HDD failed on PS4000. I replaced the HDD and reinserted the caddy back into the chassis. HDD still marked as failed. I replaced the caddy with a new one with the original HDD and reinserted into the chassis. HDD marked as failed. (I understand why: a failed drive is a failed drive forever...got it.) I replaced the original HDD with a new HDD installed in the new caddy and reinserted into the chassis. New caddy with new HDD still marked as failed. What do I need to do to get this to work? Thanks for your help!
PS 4000 does not recognize replacement HDD
