Upgrading HA for DHCP

Upgrade the HA for DHCP data service if you are upgrading from an earlier version of the HA for DHCP data service.

How to Upgrade to the New Version of HA for DHCP

Note - Before performing this procedure you should consider if your current DHCP resource has been modified to have specific timeout values that suit your deployment. If timeout values were previously adjusted you should reapply those timeout values to your new DHCP resource.

  1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
  2. Disable the DHCP resource.
    # clresource disable dhcp-resource
  3. Install the new version of HA for DHCP to each cluster.

    Refer to How to Install the HA for DHCP Package for more information.

  4. Delete the DHCP resource.
    # clresource delete dhcp-resource
  5. Reregister the DHCP resource.

    Refer to How to Register and Configure HA for DHCP for more information.

  6. Enable the DHCP resource.
    # clresource enable dhcp-resource
