controller node in the cluster and the replacement or new controller node added to the storage system.
This rescue is called a node-to-node rescue.
Automatic node-to-node rescue occurs in these circumstances:
• Installation of additional controller node pairs to upgrade the storage system
• Replacement of one or more failed node drives within a controller node
Initiating an automatic node-to-node rescue
An automatic node-to-node rescue process occurs for an HPE 3PAR StoreServ Storage controller node in
these circumstances:
• Adding one or more controller node pairs to upgrade the storage system
• Replacing one or more failed node drives within a controller node
IMPORTANT: In rare instances, a replacement node drive is not recognized as being blank, which
prevents the start of the automatic node-to-node rescue process. If the automatic node-to-node
rescue process does not start automatically, contact your authorized service provider.
Procedure
1. Partially install the controller node.
a. Pull to extend the gray rod of the controller node to the extracted position.

b. Confirm that the controller node is correctly oriented. In the controller node enclosure, the pair is
installed with each controller node oriented 180° from each other.
