Online Upgrade Process Workflow
First upgrade Cisco UCS infrastructure to the latest version and then use the automated upgrade workflow for a combined upgrade of Cisco UCS firmware and Cisco HX Data Platform. Online upgrade uses host firmware packages to upgrade all server endpoints.
During online upgrade, as one node is being upgraded (placed into maintenance mode), the number of tolerated node failures is reduced based on the Data Replication Factor and Access Policy settings.
Upgrading to HXDP 2.1(1b) may be performed as an HXDP-only upgrade without necessitating an upgrade of UCS server or infrastructure firmware. This will allow for the shortest maintenance window. However, newer SAS HBA firmware is available in this release and is recommended for long term stability [see CDETs ID CSCvb78874 in the Release Notes for Cisco HX Data Platform, Release 2.0]. If UCS server firmware update is desired, ensure that Cisco UCS Manager software is first upgraded to 3.1(2g) or later. This can be accomplished through either a brief UCSM-only upgrade or by performing a full infrastructure firmware auto install. Subsequently, the user should orchestrate upgrade of the server firmware bundle to 3.1(2g) or later using the HyperFlex vSphere Web Client Plugin.
If upgrading both HXDP and UCS firmware, either a combined or split upgrade can be selected through the vSphere Web Client plugin depending on the length of the maintenance window. Direct firmware upgrade using server firmware auto install through Cisco UCS Manager should not be attempted. Instead, use the UCS server upgrade orchestration framework provided by the HyperFlex Plugin.

Download Cisco UCS Infrastructure Software A, B, and C bundles. See Downloading Software.
Ensure that the hx-storage-data and vMotion upstream switches are configured for Jumbo Frames before proceeding forward. Otherwise the HyperFlex Cluster becomes offline and all datastores unmount from the ESXi hosts, refer Test Upstream Network Connectivity.
Upgrade Cisco UCS Infrastructure. See Upgrading Cisco UCS Firmware Using Cisco UCS Manager.
Bootstrap to upgrade Cisco HX Data Platform Plug-in. See Bootstrap Process.
Be sure to copy the bootstrap file to the controller VM
To disable snapshot schedule, on the bootstrapped storage controller VM, run the command
stcli snapshot-schedule --disable.
It is enough to run this script on one of the controller nodes.
Log in to the HX Data Platform Plug-in with administrator credentials.
Start combined upgrade of HX Data Platform and Cisco UCS firmware. See Combined Upgrade of Cisco HX Data Platform and Cisco UCS Firmware.
When only Cisco UCS firmware is being upgraded, you may see the process pause at the validation screen, after the fabric interconnect discovery. Most likely this occurs due to network connectivity failure. Please contact Cisco TAC for help.
Confirm that upgrade is complete. See Post Upgrade Tasks.
On the same controller VM, to enable snapshot schedule, run the command
stcli snapshot-schedule -–enable.
