Following remediation of VMware Identity Manager (vIDM) critical health via reboot, VMware Aria Automation (vRA) fails to start.
Users encounter the following symptoms or errors:
VMware Aria Automation 8.18.x
VMware Identity Manager 3.3.7
VMware Aria Suite Lifecycle 8.18.x
A degraded vIDM cluster prevented the identity-service-app from reaching a ready state:
Diagnose and Stabilize vIDM Cluster:
Access: https://vIDM_FQDN:8443
Review System Diagnostics and verify opensearch health reports as unknown
Identify the lead node (in this case node03)
Fix quorum and daemon failures:
Reboot the failing node if experiencing horizon-workspace daemon restart errors (e.g., node03):
On node01 and node02, manually start opensearch:
Monitor opensearch health:
Expect unassigned shards to resolve over time (may take up to 24 hours)
Once green, proceed to Aria Automation service restart
Restart Aria Automation services:
SSH to an Aria Automation appliance
Run:
Verify:
Confirm that identity-service-app pods now show 1/1 Running
UI and inventory sync should resume normal operation.
Opensearch requires quorum to function when clustered. If a lead node is inaccessible, dependent services will fail. Unassigned shards will normally self-recover post-restart, depending on shard volume and node availability. Always verify vIDM stability before restarting Aria Automation services.
