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.
