Replacing a SAS Storage Controller Card (RAID or HBA) in Riser 3
For hardware-based storage control, the server can use a Cisco modular SAS RAID controller or SAS HBA
that plugs into a horizontal socket on a dedicated mRAID riser (internal riser 3).
You cannot use a hardware RAID controller card and the embedded software RAID controller to control
front-panel drives at the same time. See
Embedded SATA RAID Controller, on page 96
for details.
Note
Storage Controller Card Firmware Compatibility
Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco
IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the storage
controller firmware using the Cisco Host Upgrade Utility (HUU) for your firmware release to bring it to a
compatible level.
See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring
server components to compatible levels:
