EQL PS4100e, SATA drive replacement with different drive firmware
Hi all.
We have a failed spare drive on an Equallogic PS4100e; RAID50.
The SAN uses OEM Seagate Constellation 2 drives with firmware revision RE12; a new drive was ordered but the drive model is not the same, the replacement drive is a Seagate Constellation 3 drive with (I assume) a newer firmware.
Installing the new replacement drive (which is also a Dell drive, but different model of the drive) does not see the drive in the SAN which, in turn, does not go to automatically rebuild the array with the new spare.
Question: mixing different drives with different drive make/model/firmware, is this supported and am I correct to assume that with a newer drive, newer model of a drive which probably contains newer firmware on the drive, will cause the drive not to be seen?
So we need to replace the drive with the same exact make/model/firmware for the array to rebuild?
Thank you in advance.

Don, thanks again.
I bring this up because this is a used SAN, no Dell warranty on the unit, and we're getting parts off of eBay (it is what it is). Having no support directly, I tend to stay with exactly the same pieces of the puzzle to make sure they fit.
Thank you.

Don, thank you for your reply.
Would you recommend that the same exact make/model of the drive be used for replacements going forward? I realize that it 'could' be that a newer version of the drive (in this case, Constellation ES3) be available and 'could' be (I'm not sure) a Dell/SAN type drive, but for sanity purposes, replacing with the same exact drive is the safest route?
Also, I understand, to confirm, that replacing the drive will prompt the SAN to automagically do its thing and rebuild the array without any further intervention (nothing else for me to do once the drive is plugged in). Correct?
Thank you.

Thank you Don.
Is there a matrix for drive compatibility for a SAN/server from Dell, that you know of? I thought there wasn't one.
Curious. Thank you.
