I have a server with a Supermicro motherboard that has an nVidia RAID controller on board. When I boot up, I can hit F10 and see/modify the RAID settings.

However, I don't want to reboot this server in order to check the status of the RAID array. Is there any kind of Linux/Ubuntu server CLI program that will let me do that? Ideally, there be an equivalent of 3ware's tw_cli program.

When installing Ubuntu, it recognized the RAID array as a single drive. I set it up without configuring software RAID. On the other hand, the lspci command reports that I have 3 of the following (not one):

00:05.0 RAID bus controller: NVIDIA Corporation MCP55 SATA Controller (rev a3) (prog-if 85)
    Subsystem: Super Micro Computer Inc Device 1411
    Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

    Capabilities: [cc] HyperTransport: MSI Mapping Enable- Fixed+
    Kernel driver in use: sata_nv
    Kernel modules: sata_nv

Furthermore the dmraid -s command returns:

*** Active Set

size   : 1953525120
stride : 128
type   : mirror
status : ok
subsets: 0
devs   : 2
spares : 0

Noticeably absent from the result of dmraid is my 3ware RAID card that is also in this server.

WHAT nVidia RAID controller? – Michael Hampton Mar 15 '13 at 13:58
sudo lspci reports is as "NVIDIA Corporation MCP55" RAID. Does that help? – hdave Mar 15 '13 at 14:37
That sounds like the usual NVIDIA fakeraid, not hardware RAID. – Michael Hampton Mar 15 '13 at 14:39
Hmmmm...ok. Updated the question to include more data. Is this the fakeraid? – hdave Mar 15 '13 at 14:58
dmraid manages fakeraid here, not 3ware hardware RAID. If you actually have a 3ware card in here, you'll have to use their tools to manage it. – Michael Hampton Mar 15 '13 at 15:01
