scm_csb_master_eligible environment variable. The master and
standby SCM must be connected to the OCP. The master SCM must
have the lowest node ID.
Use the node ID address obtained from the show csb SCM command
(see Example 7–4). If multiple primary PCI drawers are eligible, the
SCM on the PCI drawer with the lowest node ID is chosen as master.
The other SCM will be a standby in case of a problem with the master
SCM.
If the node ID switch is set to zero, the CSB node ID will be 10
(Example 7–4). If the node ID switch is set to one, the CSB node ID
will be 11.
For example, the following command enables the SCMs in the primary
PCI drawers at node IDs 10 and 11 (switch settings of 0 and 1) to be
master (and standby) of the console serial bus.
SCM_E0> set scm_csb_master_eligible 10,11
____________________ Note _____________________
The system will hang if the master SCM is not connected
to the OCP.
10. At the standby SCM, set the hp_count and hp_qbb_maskn SCM
environment variables to match the setting at the master SCM:
SCM_E0> set hp_count 2
SCM_E0> set hp_qbb_mask0 3
SCM_E0> set hp_qbb_mask1 c
11. Turn the On/Off switch to the On or Secure position, then power on each
of the partitions with the master SCM. After the power-up sequence
completes, transfer control to the SRM as shown in Example 7–2.
