OMSA Tools, Debian etch x64, mpt/sas raid

[Bryan Mclellan]

This all started due to a failed SAS disk on a Poweredge 1955. I started the sync in BIOS on a new disk then started the blade back up. I'm told that the sync/mirror will not run unless theres an agent installed. Is the mptsas driver complete enough to allow the sync to continue running and finish? I'm seeing degraded here:

But the vdisk is okay:

And the disks themselves are listed as ok.

I was thinking to do a rescan but that apparently doesn't work:

I tried a number of these, at least, I had them, but it was a slow download so I don't remember which ones I tried. I just installed 'dellomsa_5.2.0-2_amd64.deb' and it worked fine except the storage.

Rainer's tip worked though. If I stop dataeng, modprobe mptctl, then restart dataeng, the storage works. If mptctl is loaded after dataeng storage doesn't work.

So that's great. I haven't tried managing the array through this but I can at least see it's status.

I still can't log into the web interface with root / myrootpassword. OMSA looks like a typical Java mess. Does anyone know of a useful log file? I've seen references to omauth and I thought this package used PAM. Perhaps I'm missing a dependency.

Thanks folks.

Bryan

Bryan,

  I read your blog you tried an old version of dell-omsa version from our
site 5.1. Did you also tried the other versions:
   * dellomsa_5.2.0-1_amd64.deb
   * dellomsa_5.1.0-5_amd64.deb
   * dellomsa_5.2.0-2_amd64.deb

And you must also have the mptctl support in the kernel.

Regards
