If the payload application has registered to these commands via the OpenIPMI library, it gets
informed and can take all necessary actions before the payload is gracefully rebooted/shut
down.
7.13 BOOT BANK SUPERVISION SENSOR
The Boot Bank Supervision Sensor is intended to provide information on the boot bank from
which the payload has booted last. The boot bank information received from this sensor may
differ from the boot bank information received with the IPMI command "Get System Boot
Options".
7.14 BOOT FIRMWARE BOOT OPTIONS
The ATCA-9305 provides a non-volatile memory, managed by the IPMC, for storing a second
set of u-boot environment variables. Those, if present, are parsed and interpreted by the
monitor during power-up. Note that the boot parameters in the IPMC storage area have higher
priority than the same environment variables which may be configured in the firmware itself.
Furthermore, the u-boot environment variables are not overwritten with the values stored in
the IPMC memory.
The boot firmware boot options can be stored/read with the IPMI commands "Set System Boot
Options" and "Get System Boot Options" together with the OEM boot parameter #100. These
are defined in
OEM Boot Options on page 150 .
The boot firmware boot options can be modified by the ShMM or across HPI applications. The
system manager may decide from which boot device the ATCA-9305 shall boot from.
""bparam_set" and "bparam_get" is supported with the latest u-boot version.
