Cisco UCS C480 M5 - Unable to see disks for Redhat Install

[Patto]

Hi, we have a new Server - Cisco UCS C480 M5.  We have configured the x2 Physical Disks into x1 Virtual Disk and this is showing up fine in the CIMC GUI, this was done via the Advanced Menu in the BIOS.  In the CIMC, the Virtual Drive has been set as the boot disk.  When we attempt to install Redhat from a Locally Stored ISO Image, it is unable to see any disks to install to?

We followed this same process fine on x2 C460 M4's.  Does anyone know why we can't see the boot disk for the Redhat install?

Thanks

Sounds like maybe the M5 storage controller driver is not natively in the redhat installer.

If you happen to be using the onboard controller for M.2 sata drives, then that will need the megaraidSR driver that is not 'inbox' with the installer: ucs-cxxx-drivers.3.1.3/Linux/Storage/Intel/C600-M5/RHEL/RHEL7.4

Thanks,
