WeeboTech Posted April 5, 2013 Share Posted April 5, 2013 Just curious if I have to flash this card into IT mode or if I can use it with IR firmware and pass through to unRAID? Will unRAID see drives as JBOD if configured that way? Will unRAID see any RAID enabled drives? Before I start flashing away the raid functionality. Is there a reason to do that? Link to comment
jangjong Posted April 5, 2013 Share Posted April 5, 2013 I believe the reason is because M1015 is a software raid card and unraid doesn't have the correct driver for it when it's raided. and i can't find where i read it, but i read somewhere that if it's in default mode, HDD won't be detected by OS's if HDD's are not in raid. so if you dont make them in raid, hdd's wont be recognized by unraid. if you make them in raid, the raid wont be recognized by unraid. so IT firmware is necessary. but, IR in other hand may be different. in the article that you posted up about M1015, it talks about M1015 being able to be in three different mode: LSI9211-IT, LSI9211-IR, LSI9240 (Default) (http://www.servethehome.com/ibm-serveraid-m1015-part-4/) sounds like IR mode is IT mode + raid capability. but again, it comes down to unraid's raid driver. maybe someone else can answer if RAID using IR mode is supported by unraid Link to comment
WeeboTech Posted April 5, 2013 Author Share Posted April 5, 2013 maybe someone else can answer if RAID using IR mode is supported by unraid I was curious because the Areca cards can be seen in JBOD or RAID mode. It was cool having the RAID0(PARITY)/RAID1(CACHE) on the same pair of drives. Link to comment
johnodon Posted April 5, 2013 Share Posted April 5, 2013 Simple answer...yes (if you want to passthrough the entire controller). Link to comment
BobPhoenix Posted April 5, 2013 Share Posted April 5, 2013 Bare metal unRAID does not recognize a drive if you don't flash away M1015 bios. I never tried flashing to IR mode so I can't say about that but until I flashed my M1015s to IT mode unRAID could not use drives connected to it. Link to comment
