The ASR feature enables the system to reboot automatically, without operator intervention.

NOTE : For OBP version prior to 4.15, recommended settings for OBP parameters are described in FAB < Solution: 200879 > 

NOTE : For OBP version 4.15.x and above see notes at the end of document or check FAB < Solution: 200879 >

NOTE: Recommendation in FAB < Solution: 201161 > is to upgrade to OBP 4.15.6 or later

AUTOMATIC SYSTEM RECOVERY (ASR) for OBP Versions 4.6.x and Above

ok setenv auto-boot  true

ok setenv auto-boot-on-error  true

ok setenv diag-switch  true

ok setenv diag-level max

ok setenv diag-device (a value = to boot-device) disk

ok setenv post-trigger all-resets  

'post-trigger' options:

power-on-reset: Execute POST during system power-cycle on

error-reset: Execute POST on Red State Exception, Watchdog, or Fatal Reset events

user-reset: Execute POST on panic or user-initiated events (ie: reboot, reset-all).

all-reset: Equivalent of  power-on-reset error-reset user-reset 

none: Disable POST execution, excluding keyswitch & service processor.

It should be noted that the post-trigger should be set to power-on-reset and error-reset for normal operation. If user-reset (or soft-reset for 4.5.x) is included as will happen with all-resets then the system will run diagnostics every time the system receives a software reset, for example when the system is rebooted.

ok setenv obdiag-trigger all-resets

'obdiag-trigger' options:

power-on-reset : Execute OBDIAG during system power-cycle on

error-reset: Execute OBDIAG on Red State Exception, Watchdog, of Fatal Reset events

user-reset: Execute OBDIAG on panic or user-initiated events (ie: reboot, reset-all)

all-reset: Equivalent of  power-on-reset error-reset user-reset 

none: Disable OBDIAG execution, excluding keyswitch & service processor.

AUTOMATIC SYSTEM RECOVERY (ASR) for OBP Versions 4.5.x and Below

ok setenv auto-boot  true

ok setenv auto-boot-on-error  true

ok setenv diag-switch  true

ok setenv diag-level max

ok setenv diag-device (a value = to boot-device) disk

ok setenv diag-trigger soft-reset

diag-trigger variable settings that can be used:

power-reset (default): Runs firmware diagnostics only on power-on resets, including RSC-initiated power on resets.

error-reset: Runs firmware diagnostics only on resets triggered by hardware errors, including watchdog reset events. This does not include software resets.

soft-reset (recommended): Runs firmware diagnostics on all reset events, including OS system panics (including software resets).

none: Disables the automatic triggering of firmware diagnostics by any reset event. You can still invoke firmware diagnostics manually by turning the front panel keyswitch to the Diagnostics position prior to powering on the system.

ok reset-all

Non-fatal (recoverable by ASR) errors includes the following:

• SCSI/GLM Failure

• FCAL Subsystem Failure (In this case, a working alternate path to the boot disk is required.)

• Gigabit Ethernet or Fast Ethernet interface Failure

• RSC Failure

• USB Interface Failure

• Serial Interface Failure

• Any PCI Card Failure

• CPU Failure (Renders the entire module "failed", Requires another "passed" module present in the system, otherwise this is a Fatal Error)

• Memory DIMM Failure (Renders the memory bank "failed", NOT the entire GROUP. If the entire GROUP failed it would require another passed bank at a minimum.)

Note: If POST or OpenBoot Diagnostics detects a non-fatal error associated with the normal boot device, the OpenBoot firmware automatically deconfigures the failed device and tries the next-in-line boot device, as specified by the 'boot-device' configuration variable.

Fatal (non-recoverable by ASR) errors includes the following:

• Switch ASIC Failure (DAR, DCDS, MDR, BBC)

• PCI Bridge Failure

• RIO Failure

• CPU Failure (All CPU modules present failed.)

• Memory Failure (All memory banks present failed.)

• Flash RAM cyclical redundancy check (CRC) Failure

• Critical FRUPROM configuration data (CRC, consistency) Failure

To view a list of components that can be manually enabled or disabled by ASR, type the following at the ok prompt:

RECOMMENDED for NORMAL mode:

----------------------------

Diagnostics (POST/OBDIAG) are run at power-on to validate no
faulty hardware exists in configuration, prior to booting the
operating system.

Diagnostics (POST/OBDIAG) will run during any OBP detected error
event, such as Red State Exceptions, Watchdog Resets, and Fatal
Resets to identify any potential defective hardware.

Mount mount

Increased boot time and messaging only occurs during system
power-on and OBP detected error events (power-on-reset, error-reset).

These settings increase system availability when faced with
non-fatal OBP detected error events.

Recommended OBP Parameter settings (for OBP version prior to 4.15)

------------------------------------------------

 diag-switch  true

  diag-level max

  diag-script normal



   post-trigger power-on-reset error-reset





   obdiag-trigger power-on-reset error-reset



    auto-boot  true

    auto-boot-on-error  true

   diag-device (set to same value as the boot-device parameter)

    diag-file ( set to same value as the boot-file parameter)

Recommended OBP Parameter Settings (for OBP version 4.15.6 and
above )

-------------------------------------------------

 service-mode        =false

   diag-switch         =false

  diag-level          =max

   diag-script         =normal



 diag-trigger        =power-on-reset error-reset



     verbosity           =normal

   auto-boot           =true

     auto-boot-on-error  =true
