Ensure that the hx-storage-data and vMotion upstream switches are configured for full network failover capability before proceeding forward. Otherwise the HyperFlex
Cluster becomes offline and all datastores unmount from the ESXi hosts.

3.
|
Upgrade Cisco UCS Infrastructure bundle as required.
Note
|
It is important that you manually upgrade the UCS infrastructure first before initiating the upgrade sequence of the HyperFlex
components as outlined in Recommended Upgrade Method. The upgrade feature of the HX Platform software will not upgrade the UCS infrastructure bundle. This upgrade is a manual
process.

Launch the vSphere Web Client and power down all user VMs residing on HX servers and all user VMs running on HX datastores. This includes VMs
running on compute-only nodes. After the VMs have been shut down, verify the health state of the cluster and perform a graceful
shutdown.
Important
|
HyperFlex controller VMs (stCtlVMs) must remain powered on.

6.
|
Shutdown the HyperFlex Controller VMs (stCtlVMs).
|
In vCenter, right-click on each HX Controller VM (stCtlVM) and select Power > Shut Down Guest OS.
|
7.
|
Once the Controller VMs are shutdown, place the ESXi hosts into Maintenance Mode.
|
In vCenter, right-click on each ESXi host select Maintenance Mode > Enter Maintenance Mode.
|
8.
|
Acknowledge the pending reboot on the servers that comprise your HX cluster nodes, including both converged nodes and compute-only nodes connected to the cluster. Wait until all nodes are upgraded. Confirm that correct firmware packages have been installed
before proceeding.
|
|
9.
|
Once the ESXi hosts have booted, take them out of Maintenance Mode. Now the controller VM should come back online.
|
In vCenter, right-click on each ESXi host select Maintenance Mode > Exit Maintenance Mode.

Disable snapshot schedule, on the bootstrapped storage controller VM.
Note
|
It is enough to run this script on one of the controller nodes.
|
|
Run the command stcli snapshot-schedule --disable .
