C210M2 LSI MegaRAID has slot2 missing, where did it go?

[Jason Aarons]

CIMC doesn't have any errors, just seems the Slot:2

, SAS, HDD 135.972GB is missing in action

See attached screen show from MegaRAID BIOS Config Utility.

I have applied the latest host upgrade 1.3.1d.1

not sure, but could it because that drive failed?

I swapped a known good 146GB drive into that slot.  I then swapped the LSI MegaRAID card with a known good (I have a lot of spare parts:) and it seems to be the chassis drvie enclosure, which doesn't seem to be field replaceable. Calling TAC.
