An inactive cluster node has either become unreachable or has been stopped. When you delete a stopped cluster node, the operation does not remove cookie and other synchronized data. To find which cluster nodes are inactive, use the cluster_info command:
/opt/pingidentity/ase/bin/cli.sh cluster_info -u admin -p cluster id : ase_cluster cluster nodes 127.0.0.1:8020 active 220.127.116.11:8020 active 18.104.22.168:8020 inactive 172.17.0.4:8020(tasks.aseservice) active 172.17.0.5:8020(tasks.aseservice) inactive tasks.aseservice2:8020 not resolved
Using the cluster_info command output, you can remove the inactive cluster nodes 22.214.171.124:8020 and 172.17.0.5:8020.
To delete the inactive node, use the delete_cluster_node command:
/opt/pingidentity/ase/bin/cli.sh delete_cluster_node <IP:Port>
