Appendix A OBP Environment Variables
A
This chapter describes the OBP environment variables:
l
OBP Environment Variables: configuration-policy

Other OBP Environment Variables
A.1
OBP Environment Variables: configuration-policy
If a hardware fault is detected during the boot-up process, the system console can be
set to detach the target hardware and continue booting the system in a degraded state,
or to stop the boot-up procedure for the partition in which the fault was detected. The
process to be used is specified by a configuration-policy value (an OBP environment
variable). The faulty hardware can be specified in components or in system boards.
Note:
In PPAR mode, PSB is the target. In XPAR mode, XSB is the target.
Table A.1 Configuration-policy values and degraded units
Values of configuration-policy
Action
component
Continue the boot-up process in a degraded state based on a
component level fault.
board
Continue the boot-up process in a degraded state based on a
system-board level fault.
system
Stop the system; do not continue in degraded state. (Stop
activating the partition in which fault is detected.)
Remarks: The value of the configuration-policy in the main unit is set to
[component]. To check the configuration-policy value, enter the
command below at the OBP “ok” prompt.
