Does anyone know what program can be used to query the RAID status
from the OS for an on-board LSI SAS 2308-4i?
the 2308 isn't actually a megaraid, its a simple SAS HBA that has an
optional raid mode IF its flashed with IR firmware... this only supports
raid 0/1/10. I always(!) flash these with the IT firmware that
turns them back into a plain SAS HBA, and then use operating system
native raid (mdraid for centos).
the megaraid management software does support these chips in IR mode,
but megacli is an awful thing to use. i found it so awful that I
located and tweaked a couple python scripts to make it easier to use on
a LSI MegaRAID 9261-8i (which doesn't /have/ any IT mode)
