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.
SSH into each controller VM in the HX cluster and make sure that there is space in var/stv for the upgrade using the command
df -h /var/stv.
Output example /dev/sdb1 63G 2.7G 58G 5% /var/stv
If there is not enough space (usage is over 50%), contact Cisco TAC for assistance.
Verify that no major Alarms are reported for the HyperFlex cluster in the vSphere Web Client.
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.
