1 Set the number of hard partitions to two.
2 Set bits 0 and 1 of the mask (0011) to select QBB 0 and QBB 1 for
hard partition 0.
3 Set bits 2 and 3 of the mask (1100) to select QBB 2 and QBB 3 for
hard partition 1.
4 Display the SCM environment variables (non-volatile RAM) to
verify that the hard partition variables are set correctly.
5 Verify that the hard partition environment variables are correct.
6 Indicates that control will be transferred to the SRM firmware
at the end of a power-up sequence. If you want to execute SCM
commands use the escape sequence (
Esc Esc scm) to transfer
control to the SCM firmware. If you want to ensure that control
stays with the SCM at the end of a power-up sequence, set the
auto_quit_scm
SCM environment variable to zero.
7 The SCM on this primary PCI drawer is eligible to be selected
as the master SCM on subsequent power-ups. It will be
selected if it is connected to the OCP, its CSB node ID is the
lowest of the SCMs that are eligible to become master, and the
scm_csb_master_eligible
environment variable is set.
9. Select one primary PCI drawer to be the master SCM and if desired,
another primary PCI drawer to be a standby SCM by setting the
