Replacing A Boot-Optimized M.2 Raid Controller Module; Cisco Boot-Optimized M.2 Raid Controller Considerations - Cisco UCS C220 M5 Maintaining

Maintaining the Server
For servers running in standalone mode only: After you replace controller hardware (UCSC-RAID-M5 or
Note
UCSC-SAS-M5), you must run the Cisco UCS Host Upgrade Utility (HUU) to update the controller firmware,
even if the firmware Current Version is the same as the Update Version. This is necessary to program the
controller's suboem-id to the correct value for the server SKU. If you do not do this, drive enumeration might
not display correctly in the software. This issue does not affect servers controlled in UCSM mode.
See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring
server components to compatible levels:

Replacing a Boot-Optimized M.2 RAID Controller Module

The Cisco Boot-Optimized M.2 RAID Controller module connects to the mini-storage module socket on the
motherboard. It includes slots for two SATA M.2 drives, plus an integrated 6-Gbps SATA RAID controller
that can control the SATA M.2 drives in a RAID 1 array.
