EMC AX100 flare code failure caused SMART errors on multiple drives in the array
We recently experienced a problem with our EMC AX100 NAS storage array that was traced to a lost/corrupt flare code. We successfully reinstalled the flare code and the array is once again operational, however 6 out of the 12 Maxtor SATA drives are now reporting bad and will not initialize. We suspect that the corrupted flare code caused thousands of SMART errors to be logged on the drives causing the array to "think" they are bad.
We suspect that all the data is intact, but in order to put the drives back in the RAID group we need to reset the SMART counters or disable the SMART functionality altogether.
Is there a utility out there that can clear the SMART counters on the drives?

On many motherboards you can turn off the S.M.A.R.T. "reporting" in BIOS.
I recommend cloning your your drives to new ones, as running a system with the S.M.A.R.T. "reporting" disabled is not advisable.

All the data will be migrated and the device will be retired, but I need to get it up and running first. Due to all the SMART errors the array will not initialize, because it is seeing 6 "bad" drives. Since this is just an array which doesn't have a conventional BIOS I don't even think there is an option to disable SMART, unless there is a hidden menu somewhere. Unfortunately I do not have access to the EMC's partner portal to see if they have any clever utilities hidden from public view.

When I boot the array I can see "press F2 for enter Setup", however since I am connecting over a serial TTY connection I cannot send any F-key commands. There is no KVM connection on the back of the array, just serial.

you will need to remove and clone each bad drive to new drives with a PC and a cloning program then the array can be initialized with the bad drives replaced.

You can change the meaning of the SMART attributes, but that is not going to help you.
