Deleting a node from the cluster

This command deletes a node from the cluster. Use the node name that is displayed in the Cluster> show command.

Note:

This command is not supported in a single-node cluster.

If the deleted node was in the RUNNING state prior to deletion, after you reboot the node, that node is assigned to the original IP address that can be used to add the node back to the cluster. The original IP address of the node is the IP address that the node used before it was added into the cluster.

If your cluster has configured a FSS pool, you cannot use the installer to delete nodes that would result in a single node in the node group of the FSS pool.

Deleting a node from a two-node cluster that has writeback caching enabled changes the caching to read-only. Writeback caching is only supported for two nodes.

The IP address that was used by the node before it was deleted from the cluster is still accessible until you perform a restart operation.

After the node is deleted from the cluster, when you perform a reboot operation, the old IP configuration is restored. Therefore, make sure to remove the used IPs from Veritas Access for the deleted node or vice versa.

To delete a node from the cluster

  1. To show the current state of all nodes in the cluster, enter the following:
    Cluster> show
  2. To delete a node from a cluster, enter the following:
    Cluster> del nodename

    where nodename is the node name that appeared in the listing from the Cluster> show command. You cannot specify a node by its IP address.

    For example:

    Cluster> del snas_01
  3. After a node is deleted from the cluster, the physical IP addresses that it used are marked as unused physical IP addresses. The IP addresses are available for use if you add new nodes. The virtual IP addresses used by a node that have been deleted are not removed. Deleting a node moves the virtual IP addresses on the deleted node to the remaining nodes in the cluster.

    For example: 

    Network> ip addr show
IP            Netmask/Prefix  Device     Node            Type     Status
--            --------------  ------     ----            ----     ------
192.168.30.10 255.255.252.0   pubeth0    source_30a_01   Physical
192.168.30.11 255.255.252.0   pubeth1    source_30a_01   Physical
192.168.30.12 255.255.252.0              ( unused )      Physical
192.168.30.13 255.255.252.0              ( unused )      Physical
192.168.30.14 255.255.252.0   pubeth0    source_30a_01   Virtual  ONLINE (Con IP)
192.168.30.15 255.255.252.0   pubeth0    source_30a_01   Virtual  ONLINE
192.168.30.16 255.255.252.0   pubeth0    source_30a_01   Virtual  ONLINE
192.168.30.17 255.255.252.0   pubeth1    source_30a_01   Virtual  ONLINE
192.168.30.18 255.255.252.0   pubeth1    source_30a_01   Virtual  ONLINE

    If the physical or virtual IP addresses are not going to be used, they can be removed using the following command:

    Network> ip addr del ipaddr

    For example:

    Network> ip addr del 192.168.30.18
ACCESS ip addr SUCCESS V-288-1031 ip addr del successful.

Note:

If you have configured NIC bonding for the cluster, you also need to delete the configuration of the deleted node on the switch.
