Removing and adding back nodes to an Azure RedHat OpenShift (ARO) cluster

If any node is removed from an Azure RedHat OpenShift (ARO) cluster, you can run the following steps to remove that node from the InfoScale cluster.

Be ready with the names of the nodes to be removed and the IP addresses of the nodes to be added.

Note:

You can remove one node at a time. To remove multiple nodes, run the following steps for every node.

  1. Run the following command by logging on the infoscale-driver-container pods of all nodes other than the node to be removed.

    gabconfig -m <Number of nodes minus 1>

  2. Log on by using Exec command to one of the infoscale-driver-container pods other than the pod scheduled on the node you want to be removed.
  3. Run the following commands

    /opt/VRTSvcs/bin/haclus -value ReadOnly

    Skip if the output of the above command is 1. If the output of the above command is not 1, run /opt/VRTSvcs/bin/haconf -makerw

    ./opt/VRTSvcs/bin/hares -modify cvm_clus CVMNodeId -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hagrp -modify RestSG AutoStartList -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hagrp -modify RestSG SystemList -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hagrp -modify cvm AutoStartList -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hagrp -modify DISK_GROUP SystemList -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hagrp -modify cvm SystemList -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/hasys -delete <name of the node to be removed>

    /opt/VRTSvcs/bin/haconf -dump -makero

    /opt/VRTSvcs/bin/haclus -value DumpingMembership

  4. One-by-one, log on by using Exec command to all of the infoscale-driver-container pods other than the pod scheduled on the node you want to be removed and run the following commands.

    • /opt/VRTS/bin/vxclustadm -m vcs reinit

    Edit /etc/llthosts and delete the name of the node you want to be removed.

  5. Run the following command

    oc edit infoscalecluster infoscalecluster-dev

    Delete all information about the node you want to remove from clusterInfo.

  6. Run the following commands to verify that the node is removed.

    oc describe cm infoscalecluster-dev-configmap -n infoscale-vtas

    oc describe infoscalecluster

  7. Run the following command on all nodes in the cluster to add a new node.

    lltconfig -a set <ID of the new node> link0 <IP address of the new node>

  8. Update /YAML/OpenShift/cr.yaml with the new node information.
  9. Run oc apply -f /YAML/OpenShift/cr.yaml on the bastion node.
