Replacing A Controller Node-Two-Node System Only-Sp 4.X - HPE 3PAR StoreServ 7000 Storage Service And Upgrade Manual

CAUTION:
• To avoid possible data loss, only shutdown and remove one Controller Node at a time from the
storage system.
• Before shutting down a Controller Node in the cluster, confirm that the other Controller Nodes in
the cluster are functioning normally. Shutting down a Controller Node in the cluster causes all
cluster resources to fail over to the other Controller Node.
• If the Controller Node is properly shut down (halted) before removal, the storage system will
continue to function, but data loss might occur if the replacement procedure is not followed
correctly.
• Verify that host multipathing is functional.
• To prevent overheating, do not exceed 30 minutes for the removal of the Controller Node.
IMPORTANT:
Only a Controller Node for a two-node system that does not contain a Host PCIe Adapter qualifies
for a Customer Self Repair (CSR). It is the entire Controller Node that qualifies for a CSR and
excludes the repair of internal components within the Controller Node. Any internal components
within the Controller Node are only serviceable by an authorized service provider (ASP).
If the Controller Node is properly shut down (halted) before removal, the storage system will continue to
function, but data loss might occur if the replacement procedure is not followed correctly.
Procedure
• Based on your HPE 3PAR Service Processor (SP) software version, select and complete a
replacement procedure:
◦ Replacing a Controller Node—Two-node system only—SP 4.x on page 8
◦ Replacing a Controller Node—Two-node system only—SP 5.x on page 11
Replacing a Controller Node—Two-node system only—SP 4.x
This procedure is for the replacement of an HPE 3PAR StoreServ 7000 Storage Controller Node using
HPE 3PAR Service Processor (SP) 4.x.
Prerequisites
For the identification and shutdown of the Controller Node, contact your Hewlett Packard Enterprise
authorized service provider (ASP) for assistance in completing this task.
Procedure
Preparation:
1. Unpack the component and place on an ESD safe mat.
2. Connect to the HPE 3PAR Service Processor (SP).
Browse to either the IP address or hostname: https://<sp_ip_address> or https://
<hostname> .
