    Default GA-Q77M-D2H unable to expand RAID5 array

    The Q77 chipset supports adding disks to existing RAID arrays and will expand the array accordingly. It's called "capacity expansion" in the specs (check PCH column):
    Intel® Rapid Storage Technology (Intel® RST) — RAID features by chipset/controller hub

    On my GA-Q77M-D2h the Add Disk command isn't available and, according to Intel Support, this is because the Gigabyte motherboard BIOS is not enabling the capacity expansion feature in its bundled RAID option ROM.

    How can I have this solved?

    Thanks
    Mike

    I never paid attention but see the ICH10R has that option as well, but in my RAID utility I have never seen that option.. (though I never looked for it).

    What RAID configuration do you have setup? RAID 0, 5 or 10?

    Vin
    Main Rig
    OS = Win8.1
    CPU = i7-980X @ 4.17Ghz 144x29 cooled by custom Loop
    Mem = 12GB 2000Mhz corsair Dominator GT at 2010Mhz @ 9-10-9-27-2T
    MB = Gigabyte GA-X58A-UD5 v1.0 with F6 Bios - Dead Board
    MB = EVGA X58 Classified3 e770
    GPU = 2x Sapphire r9 290x in xfire
    HD = 2x Toshiba 120GB Raid 0 (580MB Read/140MB Write)
    Storage = 2TB WD Black
    PSU = EVGA SuperNOVA 1300w
    Case = Cooler Master HAF-X 945

    HTPC / Home Server
    OS = Win7 64Bit running XBMC HTPC Front end with Windows Server 2011 Virtual Machine with 8GB ram assigned for homer server with exchange
    CPU = AMD 1090T
    Mem = 16GB 1600Mhz Kingston RED Limited Edition running at 1600Mhz
    MB = Gigabyte 790FXTA-UD5
    GPU- EVGA GT210
    HD = too many to count, but about 5TB of storage all together including backup
    PSU = Corsair TX750
    Case = Too embarrassed to mention.

    I have RAID5 on 3x WD RED 3TB disks.

    Intel's RAID utility ("Intel RST") makes use of dynamic menus that completely hide stuff that isn't currently possible to do. F ex, running RAID initialization hides the cache settings menu and it reappears when initialization is done.
    The Add Disk command only shows up in the Intel RST application when you select an array or volume of RAID type 0 or 5 and have a free disk of the same geometry as the ones in the array. So yes, normally you don't see this command :-)

    Intel has verified that Add Disk should become available with my setup and the only thing stopping it could be the motherboard BIOS (due to what features it reports to RST).

    Ah, OK. that would make sense then. I have an EVGA board now but it still has an ICH10R controller. I have a few SSD laying around, I'll plug one in and see if I see this option. Where specifically should I see it in the IRST software?

    You can see the Add Disk command in the IRST screenshot towards the bottom of this page:
    http://www.anushand.com/2011/02/vert...y-anymore.html
    Note that the volume is selected on the right and this shows the commands available on the left. Actually it seems to be enough there is a free disk of the same or larger size to enable the Add Disk command.

    After some experimenting I found that Add Disk appeared when the RAID volume wasn't booted from. Intel Support wasn't aware of this limitation and it's not mentioned in the docs so it remains to be seen if expanding a volume you boot from should be supported or not. Either way it doesn't seem to be the motherboard BIOS that is at fault here.

    ok, good to know, I have a spare SSD to test this with, now I have something else to check with.
