I have a Dell server running Win Server 2012. The machine has a 9260 (genuine) in it for four internal SAS drives in RAID10, a PERC H800 running 8 4tb disks in RAID6 in an external enclosure, and a 9211-IT (also genuine) connected to an enclosure with 7 DVD burners and one hot-swap SAS bay. The 9211 is running the P16 driver for Win 8/2012 and the latest LSI firmware.
The odd thing is that Windows only appears to see 4 of the DVD drives and the hot-swap SAS bay (if occupied). Device Manager and Disk Management also only show 4 DVDs. MRM shows all the controllers and all of the drives (HDD and DVD) connected. The DVDs that Win sees work perfectly (including BDXL burns).
If I switch to IR firmware, all of the DVD drives become visible in Windows and MRM but writing DVDs gets flaky (reads are fine). I've also tried a cross-flashed M1015 but that was much worse (Dell plays with Dell and LSI but not with anyone else, it seems). I've also got a collection of PERC H310s, some with IT firmware and some with IR firmware (both from Dell). The PERC H310s have exactly the same issues as the 9211. I've tried the P16 drivers in WinPE 3.1 x64 as well. In IT mode, only three DVDs and the SAS bay are visible.
I have another external enclosure with 8 SAS bays, 4 DVD burners and an Intel SAS expander which I'm hoping to hang off a Dell workstation using a 9211 (the H310 in IR mode doesn't like the expander - I haven't tried one in IT mode) but it seems unlikely if I can't get the simpler configuration to work.
What am I missing?
Any help would be greatly appreciated (even if it does expose my lack of understanding!).
