Important |
If your environment (or deployment) is a Fabric Interconnect 6400 connected to VIC 1455/1457 using SFP-H25G-CU3M or SFP-H25G-CU5M cables, only use UCS Release 4.0(4k), or 4.1(2a) and later. Do not use the any other UCS version listed in the table of qualified releases. Using a UCS Release that is not UCS Release 4.0(4k), 4.1(1e) or 4.1(2a) and later may cause cluster outages. Refer to Release Notes for UCS Manager, Firmware/Drivers, and Blade BIOS for any UCS issues that may affect your environment. Use the following upgrade sequence ONLY for Fabric Interconnect 6400 connected to VIC 1455/1457 using SFP-H25G-CU3M or SFP-H25G-CU5M cables:
If you have the above hardware and software combination, combined upgrade of UCS server firmware is not supported. However, combined upgrade of HXDP and ESXi is supported after UCS server firmware and UCS infrastructure firmware upgrade is completed. If the current UCS F/W version is above 4.0(4k), 4.1(1e), or 4.1(2a), then combined upgrade of UCS server firmware, HX and ESXi is supported. |
The HX components—Cisco HX Data Platform Installer, Cisco HX Data Platform, and Cisco UCS firmware—are installed on different servers. Verify that each component on each server used with and within an HX Storage Cluster are compatible.
-
Verify that the preconfigured HX servers have the same version of Cisco UCS server firmware installed. If the Cisco UCS Fabric Interconnects (FI) firmware versions are different, see the Cisco HyperFlex Systems Upgrade Guide for VMware ESXi, Release 4.0 for steps to align the firmware versions.
-
M5: For NEW hybrid or All Flash (Cisco HyperFlex HX240c M5 or HX220c M5) deployments, verify that the recommended UCS firmware version is installed.
-
To reinstall an HX server, download supported and compatible versions of the software. See the Cisco HyperFlex Systems Installation Guide for VMware ESXi for the requirements and steps.

Important: For Intersight edge servers running older than 4.0(1a) CIMC version, HUU is the suggested mechanism to update the firmware.
