Replacing a node or node component

Using the DARE utility, you can add or remove a node while the cluster is running.

If you are replacing a cluster node keep this list in mind:

  • The new node must typically have the same amount of RAM (or more) as the original cluster node.
  • The new node must typically be the same type of system if your applications are optimized for a particular processor.
  • The new node's slot capacity typically must be the same or better than the old node.
  • NIC physical placement is important - use the same slots as originally assigned.
  • Get the new license key from the application vendor for the new CPU ID if necessary.

If you are replacing a component of the node:

  • Be aware of CPU ID issues.
  • For SCSI adapter replacement - reset external bus SCSI ID to original SCSI ID.
  • For NIC replacement - use the same slots as originally assigned.
