Preparing the Partitions for Shutdown
IMPORTANT: Before powering off the cabinets, HP recommends first that all partitions be

for them to reach EFI or BCH and execute the RR command.
To ensure that all partitions are ready to be shut down, follow these steps:
1. From the CM> prompt, issue an rr command (Figure C-8).
2. Enter the partition number, and when prompted for reset of the partition number, enter Y
.
