PS6100 Unsupported drive

Hi all,

I'm looking to see if there are ANY scenarios for seeing the dreaded "unsupported drive" error message other than a drive that doesn't have EQL firmware on it.  Initially we accidentally ordered a W347K to replace a failed 600GB disk, which isn't EQL branded, so not surprisingly we saw the unsupported drive message.  Then we ordered an EQL branded disk from a third party and installed it. The label looks like a dell/EQL/enterprise storage label with p/n 02R3X, and it spins up and looks like it should work fine, but we get the same unsupported drive error.  DOA disk?  Firmware mismatch?  Anything else it could be?  I'm thinking the vendor somehow overwrote the Equallogic firmware, or printed their own label and slapped it on over the top of a generic seagate label.  I don't have a way to physically look at the disk myself so I'm probably drawing a couple of unfair conclusions.

Thanks,
