We run a Rocks 6.2 cluster, that we've upgraded to CentOS 6.9:

# rocks list roll
> NAME               VERSION    ARCH   ENABLED
> ganglia:           6.2        x86_64 yes

When trying to add a Dell R640 w/ two SSD, at boot time (BIOS set to AHCI),
we get

Initializing Serial ATA device
> 
> PowerEdge Expandable RAID Controler BIOS
> AH -0 (Bus 24 Dev 0) PERC H740P Mini
> FW package: 50.3.0-1512
> 
> 1 Virtual Drive(s) found on the host adapter.
> 
> 0 Non-RAID disk(s) handled by BIOS
> 1 Virtual drive(s) handled by BIOS
> 

The machine boots up, starts anaconda but then croaks on "No usable disks
have been found."

Dell is telling us to add the driver in
UnifiedDriver_7.703.06.00_RHEL6.tar.gz, namely
kmod-megaraid_sas-07.703.06.00_el6.9-1.x86_64.rpm
I can "rpm -ivh" that module on the frontend (so no compatibility issue),
but it is unclear to me how to add to the distro to activate it when
booting via PXE a new node.

Any hints? Thanks.

[Yes, we need to migrate to Rocks 7, but we're not yet ready]

  Cheers,
    Sylvain
