Reset Scenarios; Table - Fujitsu SPARC Enterprise T2000 Administration Manual

If a fatal error is detected by POST or OpenBoot firmware, the system does not
■
boot regardless of the settings of auto-boot? or auto-boot-on-error?. Fatal
nonrecoverable errors include the following:
Any CPU failed
■
All logical memory banks failed
■
Flash RAM cyclical redundancy check (CRC) failure
■
Critical field-replaceable unit (FRU) PROM configuration data failure
■
Critical system configuration card (SCC) read failure
■
Critical application-specific integrated circuit (ASIC) failure

For more information about troubleshooting fatal errors, refer to the service manual
for your server.

Reset Scenarios

Three ALOM CMT configuration variables, diag_mode, diag_level, and
diag_trigger, control whether the system runs firmware diagnostics in response
to system reset events.
The standard system reset protocol bypasses POST completely unless the virtual
keyswitch or ALOM CMT variables and are set as follows:
Virtual Keyswitch Setting for Reset Scenario

TABLE 2-3

Keyswitch Value
virtual keyswitch
diag
ALOM CMT Variable Settings for Reset Scenario
TABLE 2-4
Variable Value
normal or service
diag_mode
min or max
diag_level
diag_trigger power-on-reset error-reset
The default settings for these variables are:
diag_mode = normal
■
diag_level = min
■
diag_trigger = power-on-reset
■
Therefore, ASR is enabled by default. For instructions, see
Automatic System Recovery" on page 38.
