Info

Note – The standard (default) configuration is recommended for improved fault isolation and system restoration, and for increased system availability. TABLE 8-3 OpenBoot Configuration Variables That Control Diagnostic Testing and Automatic System Restoration OpenBoot Configuration Variable auto-boot? auto-boot-on-error? boot-device boot-file diag-device diag-file diag-level diag-out-console diag-passes Description and Keywords Determines whether the system automatically boots. Default is true. • true – System automatically boots after initialization, provided no firmwarebased (diagnostics or OpenBoot) errors are detected. • false – System remains at the ok prompt until you type boot. Determines whether the system attempts a degraded boot after a nonfatal error. Default is true. • true – System automatically boots after a nonfatal error if the variable auto-boot? is also set to true. • false – System remains at the ok prompt. Specifies the name of the default boot device, which is also the normal mode boot device. Specifies the default boot arguments, which are also the normal mode boot arguments. Specifies the name of the boot device that is used when diag-switch? is true. Specifies the boot arguments that are used when diag-switch? is true. Specifies the level or type of diagnostics that are executed. Default is max. • off – No testing. • min – Basic tests are run. • max – More extensive tests might be run, depending on the device. Memory is extensively checked. Redirects system console output to the system controller. • true – Redirects output to the system controller. • false – Restores output to the local console. Note: See your system documentation for information about redirecting system console output to the system controller. (Not all systems are equipped with a system controller.) Specifies the number of consecutive executions of OpenBoot Diagnostics selftests that are run from the OpenBoot Diagnostics (obdiag) menu. Default is 1. Note: diag-passes applies only to systems with firmware that contains OpenBoot Diagnostics and has no effect outside the OpenBoot Diagnostics menu. 146 Sun Fire V445 Server Administration Guide • August 2006
TABLE 8-3 OpenBoot Configuration Variables That Control Diagnostic Testing and Automatic System Restoration (Continued) OpenBoot Configuration Variable diag-script diag-switch? diag-trigger error-reset-recovery Description and Keywords Determines which devices are tested by OpenBoot Diagnostics. Default is normal. • none – OpenBoot Diagnostics do not run. • normal – Tests all devices that are expected to be present in the system’s baseline configuration for which self-tests exist. • all – Tests all devices that have self-tests. Controls diagnostic execution in normal mode. Default is false. For servers: • true – Diagnostics are only executed on power-on reset events, but the level of test coverage, verbosity, and output is determined by user-defined settings. • false – Diagnostics are executed upon next system reset, but only for those class of reset events specified by the OpenBoot configuration variable diag-trigger. The level of test coverage, verbosity, and output is determined by user-defined settings. For workstations: • true – Diagnostics are only executed on power-on reset events, but the level of test coverage, verbosity, and output is determined by user-defined settings. • false – Diagnostics are disabled. Specifies the class of reset event that causes diagnostics to run automatically. Default setting is power-on-reset error-reset. • none – Diagnostic tests are not executed. • error-reset – Reset that is caused by certain hardware error events such as RED State Exception Reset, Watchdog Resets, Software-Instruction Reset, or Hardware Fatal Reset. • power-on-reset – Reset that is caused by power cycling the system. • user-reset – Reset that is initiated by an OS panic or by user-initiated commands from OpenBoot (reset-all or boot) or from Solaris (reboot, shutdown, orinit). • all-resets – Any kind of system reset. Note: Both POST and OpenBoot Diagnostics run at the specified reset event if the variable diag-script is set to normal or all. Ifdiag-script is set to none, only POST runs. Specifies recovery action after an error reset. Default is sync. • none – No recovery action. • boot – System attempts to boot. • sync – Firmware attempts to execute a Solaris sync callback routine.
