HyperFlex Node Upgrade Validations
Perform the following validations on each HyperFlex node before moving on to upgrade the next node in the cluster.
-
Verify that the HyperFlex cluster is healthy and online. Verify all HyperFlex cluster nodes are connected to the vCenter and are online.
-
Verify that no major Alarms are reported for the HyperFlex cluster in HyperFlex Connect.
-
Verify that DRS is enabled and set to fully automated.
-
Verify that vSphere services are running and ESXi Agent Manager (EAM) health is normal.
-
Verify the health of the cluster in Cisco UCS Manager.
-
SSH into each controller VM in the HX cluster and run the command df -h to ensure that there is at least 50% free space in /var/stv.

If there is not enough space (usage is over 50%), contact Cisco TAC for assistance.
