Predictive Self-Healing Article
A component in a FRU signaled it has failed.

Type

: Fault; fault.chassis.device.fail

Severity

: Critical

Description

: A component in a FRU has signaled it has failed. Please consult the detail section of the knowledge article for additional information.

Automated Response

: The component in the FRU will be deconfigured (which may cause the FRU to be deconfigured). Please consult the detail section of the knowledge article for additional information.

Impact

: Domains may be reset, the platform may become unbootable, or the platform may be powered down. Please consult the detail section of the knowledge article for additional information.

Suggested Action for System Administrator

Component(s) can be marked faulty for this error when there are issues with the power supplied to the system. Components marked faulty due to problems with the input power will need to have the fault cleared ( if xcp level is below xcp1115 by a service technician ) but should not be replaced. Verify the power provided to the system is stable and schedule a repair action to replace the affected Field Replaceable Unit (FRU).

Details

: A component in a FRU has signaled it has failed.

The FRU or device that has signaled that it has failed can be identified from the FMRI of the fault event.

The following section provides a list of the potential FRUs and devices
that can signal a failure condition, and specifies the impact and automated
actions taken by the platform or domain in response to the fault.

   SPARC Enterprise M3000 platform:

      DDC ( DC to DC converter ) on Motherboard Unit (MBU):

         Platform is powered down and will not be powered up.
         Platform becomes unbootable.

   SPARC Enterprise M4000/M5000 platforms:

      PSU:

         PSU is deconfigured.

         If there are now insufficient PSU's to power the platform,
         then the platform is powered down and the platform becomes unbootable.
         Otherwise, no other action is taken.

      DDC ( DC to DC converter ) on a CPU Module:

         CPU Module is powered down and the domain using the CPU Module is reset.
         CPU Module is deconfigured.

      DDC_A on a Motherboard:
      DDC_A on an IOU:
      DDC_B on a Motherboard:
      DDC_B on a DDC Riser on an IOU:

         Platform is powered down and will not be powered up.
         Platform becomes unbootable.

   SPARC Enterprise M8000/M9000 platforms:

      PSU:

         PSU is deconfigured.

         If there are insufficient operational PSUs to power the platform,
         then the platform is powered down and the platform becomes unbootable.
         Otherwise, no other action is taken

      DDC_A on a Backplane (BP_A):

         If there remain sufficient operational DDC_A's, then the DDC_A is deconfigured.
         If there remain non-operational DDC_A's, then platform is powered down
         and the platform becomes unbootable.

      DDC ( DC to DC converter ) on a CPU Module (CPUM):

         DDC's on the CPU Module are redundant.

         If there remain sufficient operational DDC's on the CPU Module,
         then no action is taken and nothing is deconfigured.

         Otherwise, the CPU Module is powered down and the domain using the CPU Module is reset.
         CPU Module is deconfigured.

      DDC on a CPU/Memory Unit (CMU):

         DDC's on the CMU are redundant.

         If there remain sufficient operational DDC's on the CMU,
         then no action is taken and nothing is deconfigured.

         Otherwise, the CMU is powered down and the domains using the CMU are reset.
         CMU is deconfigured, along with all of its associated I/O.

      SSM on a CPU/Memory Unit (CMU):

         CMU is powered down and the domains using the CMU are reset.
         CMU is deconfigured, along with all of its associated I/O.

      DDC on an Crossbar Unit (XBU):

         DDC's on an XBU are redundant.

         If there remain sufficient operational DDC's on an XBU,
         then no action is taken and nothing is deconfigured.

         Otherwise, platform is reset and the crossbar way is deconfigured.

            If this is the first crossbar way being deconfigured,
            then the platform will operate with reduced performance.

            If a crossbar way has already been deconfigured,
            then the platform will be powered down.

      Slow Start Module (SSM) on a Crossbar Unit (XBU):

         XBU is powered off.
         Platform is reset and the crossbar way is deconfigured.

            If this is the first crossbar way being deconfigured,
            then the platform will operate with reduced performance.

            If a crossbar way has already been deconfigured,
            then the platform will be powered down.

      DDC on an IO Unit (IOU):

         DDC's on an IOU are redundant.

         If there remain sufficient operational DDC's on an IOU,
         then no action is taken and nothing is deconfigured.

         Otherwise, the IOU is powered off and the domains using the IOU are reset.
         IOU is deconfigured.

      Slow Start Module (SSM) on an IO Unit (IOU):

         IOU is powered off and the domains using the IOU are reset.
         IOU is deconfigured.

      DDC on a Clock Unit (CLKU):

         DDC's on a Clock Unit are N+1 redundant.

         If there remain sufficient operational DDC's on a Clock Unit,
         then no action is taken and nothing is deconfigured.

         If this is the active Clock Unit and there are insufficient operational
         DDCs on the active Clock Unit, then the active Clock Unit is powered off,
         the platform is reset, and the active Clock Unit is deconfigured.

         If this is the standby Clock Unit and there are insufficient operational
         DDCs on the standby Clock Unit, then the standby Clock Unit
         is powered off and no further action is taken.

Component(s) can be marked faulty for this error when there are issues with the power supplied to the system.
Components marked faulty due to problems with the input power will need to have the fault cleared ( if xcp level is below xcp1115 by a service technician ) but should not be replaced.
Verify the power provided to the system is stable and schedule a repair action to replace the affected Field Replaceable Unit (FRU).
