____________________ Notes ____________________

If the OCP key switch is in the On or Secure position, the system will go through the power-up sequence.

In this case, when the power-up sequence terminates, power down the system with the power off SCM command, then partition the system.

If the auto_quit_scm SCM environment variable is set (equal 1), control will be passed to the SRM firmware at the end of the power-up sequence. Use the escape sequence (Esc Esc scm) to transfer control to the SCM firmware. If the auto_quit_scm SCM environment variable is not set (equal 0), the SCM retains control.

If you execute the power off command at the master SCM, without designating a partition, power is turned off to the entire system. To turn power off to a partition, use the SCM power off -parn, where n is the partition number.

A slave SCM can only control power for its own partition.

8.When the power-up and built-in self tests (BIST) have completed, and the system has been powered down, use the master SCM to set the SCM environment variables to define the partitions.

The hp_count SCM environment variable defines the number of hard partitions. The hp_qbb_maskn SCM environment variables define which QBBs, by bit position, will be part of partition n. Example 7–1 shows how to set up two partitions, with each partition containing two QBBs. Partition 0 includes QBBs 0 and 1; partition 1 includes QBBs 2 and 3.

Use the show nvr SCM command to display the SCM environment variables.
