See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring server components This issue does not affect servers controlled Not do this, drive enumeration might not display correctly in the software. This is necessary to program the controller's suboem-id to the correct value for the server SKU. UCS Host Upgrade Utility (HUU) to update the controller firmware, even if the firmware Current Version is the same as the Utility (HUU) for your firmware release to bring it to a compatible level.įor servers running in standalone mode only: After you replace controller hardware (UCSC-RAID-M5, UCSC-RAID-M5HD, UCSC-SAS-M5, or UCSC-SAS-M5HD), you must run the Cisco If not compatible, upgrade or downgrade the storage controller firmware using the Host Upgrade Storage Controller Card Firmware Compatibilityįirmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco IMC and BIOS versions NOTE: This HBA does not support optical cables for connection to external storage (copper only). This controller is supported only in the following server version:Ģ4 front-loading, plus 2 rear-loading SAS/SATA drivesĬisco 12G Modular SAS HBA (For Up To 24 Drives)Ĭisco 12G 9400-8e HBA for external JBOD attachĨ external SAS/SATA ports, controlling up to 1024 external drives.
