equallogic issue. replacement drive not approved.

I have an Equallogic 6100 with multiple failed HDDs. Its out of warranty and I ordered and received HDDs. Refurb Dell SAS drives. Same exact model and on the label the firmware says it's the same. When I insert them they give me the error that they're not approved and are unavailable.

Any ideas?

A few things
*  The firmware on the label doesn't have to match the firmware on the drive.   Depending on the model, you might see an update every 4-6 months.
*  Even having the right disk with the correct firmware doesn't necessarily mean it will work.  For those vendors who legitimately "refurbish" a drive, they use software to wipe it.  The vendors who do not know what they are doing won't restore all the hundreds of configurable firmware settings.  
* The vendors who REALLY don't know what they are doing will reformat them in process of wiping and/or change the block sizes and/or record layout for bad blocks.  That may make the drive suitable for windows/PC use, but not your storage appliance.


Gut feeling I believe you have drives that have multiple problems having to do with some bozo vendor reprogramming them.  This is fixable, but you need a pro with the right software to reprogram/reconfigure your disks.   He/she also needs a known good working drive as a model.  

It could take hours or a half day of engineering time,  depending on whether or not they mucked with block size or bad block layouts because it is such a pain to do and there are some undocumented settings, and perhaps, God forbid some security/encryption constraints.  Even then a used drive is a used drive, and you have no idea whether or not your data is safe on it.

My suggestion,  get a new drive directly from the vendor that has a warranty.    If somebody like me tried to qualify/program that drive then I'd end up charging you more than you want to pay.

the drive doesn't carries the correct firmware so its rejected from the SAN...you should return it or buy another...

even though it states it has the correct firmware on the label?

Mistakes happen...maybe its a minor subversion that is not on the label.....if you have no way out there is a chance by swapping the PCB from one of the failed drive to get it "approved" but i haven't tried it ..

Firmware matters.  If you value your data then you will buy NEW disks with proper firmware.  
In fact the controller on that system cares so much about the proper firmware that it is rejecting those drives..   What does that tell you?

On enterprise storage systems such as these, the proper firmware does a great deal of customization when it comes to retry timing, thresholds.  Furthermore one of the log pages is custom, there are about 10 counters there that do NOT exist on stock SEAG firmware.   W/O those counters the drive won't be able to properly assess health.

ok so i've tried 3 drives that are the exact same drive model, brand, firmware, size, P/N and they all say "not approved". I've got 3 drives that are bad and i've tried those drives in different slots with the same error.

these drives are from 3 different vendors. I even tried getting one from Dell but they don't sell them anymore.

so I finally got 2 drives in that worked for the Equallogic.

My best guess/detective work, would be that even though all 7 of the previous drives were identical physically and had the correct P/N that during their previous lives or during the refurb process the firmware was flashed to an incompatible version. The 2 that came in on Friday were specifically labeled for Equallogic.
