I have a nearline storage server where the LSI RAID controller died over the holidays: 20 x 6TB drives on a LSI 9280-24ie4. Controller dead as a door nail, didn't even show up in the BIOS boot screen.
Replacement controller arrived today, installed it, go to BIOS setup menu, and I get the dreaded "ERROR IMPORTING FOREIGN CONFIGURATION". The controller sees all the drive as "Foreign / Unconfigured". Most of the googling I've done shows examples where drives are marked BAD, so marking them GOOD allows the configuration to be imported but that's not my situation, none of my drives are marked BAD.
