Service Processor-to-Node Rescue
CAUTION: Before proceeding with the controller node rescue, verify with the system administrator
before disconnecting all host cables or shutting down the host.
NOTE: This SPMAINT node-rescue procedure should only be used if all nodes in the 3PAR system
are down and needs to be rebuilt from the HP 3PAR OS image on Service Processor. The SP-to-node
rescue procedure is supported with HP 3PAR OS version 3.1.2 or higher and HP 3PAR Service
Processor 4.2 or higher.
To perform SP-to-node rescue:
1. At the rear of the storage system, uncoil the red crossover Ethernet cable connected to the SP
(ETH) private network connection and connect this cross-over cable to the E0 port of the node
that is being rescued.
