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 -par
n
, 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_mask
n
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.
