Edges are upgraded as part of Edge Upgrade Unit Groups
There is a 1:1 mapping of Edge clusters to Edge Upgrade Unit Groups
New Edge Upgrade Unit Groups cannot be created and Edges cannot be moved from one Upgrade Unit to another
Edge upgrade is expected to result in some datapath and service disruption as any active Gateways will need to failover to another Edge in the cluster.
Environment
VMware NSX VMware NSX-T
Resolution
Admin cli to check upgrade status:
get upgrade progress-status
Logs:
On the Edge /var/log/syslog can be reviewed for errors
On the Manager /var/log/upgrade-coordinator/upgrade-coordinator.log is the main upgrade log
To RCA an Edge upgrade failure logs from both Manager and Edge should be collected. If unavailable through the UI, Edge logs can also be collected from admin cli using get support-bundle file <filename.tgz>
