Uninstalling IBM Cloud Pak for AIOps on Linux

Procedure

Use the following steps to uninstall IBM Cloud Pak for AIOps from your Linux cluster.

1. Export environment variables.

   Important: If you used an alternative path for APP_STORAGE_PATH when you set up your local application storage in Configuring local volumes, then you must change the value of this environment variable accordingly.

   export TARGET_USER="root"
   export CONTROL_PLANE_NODE="<control_plane_node_1>"
   export ADDITIONAL_CONTROL_PLANE_NODES=(
     "<control_plane_node_2>"
     "<control_plane_node_3>"
   )
   export WORKER_NODES=(
     "<worker_1>"
     "<worker_2>"
     "<worker_3>"
     "<worker_4>"
     "<worker_5>"
     "<worker_6>"
     "<worker_7>"
   )
   export APP_STORAGE_PATH="/var/lib/aiops/storage"
   

   
   

   Where:

   • <control_plane_node_n> is the FQDN or IP address of your control plane node. For example, "control-plane.example.com"
   • <worker_n> - is the FQDN or IP address of each worker node, where n is the number of nodes. For example, "worker-1.example.com"

2. Run the following commands from the control plane node:

   for WORKER_NODE in "${WORKER_NODES[@]}"
   do
     ssh ${TARGET_USER}@${WORKER_NODE} aiopsctl cluster node down --role worker --app-storage ${APP_STORAGE_PATH}
   done
   
   for CP_NODE in "${ADDITIONAL_CONTROL_PLANE_NODES[@]}"
   do
     ssh ${TARGET_USER}@${CP_NODE} aiopsctl cluster node down --role control-plane
   done
   
   aiopsctl cluster node down --role control-plane
