Solution 2054499.1 : Sun SPARC[TM] Enterprise M4000/M5000: all platform components (MBU and all CHIPs, MEMBs, IOUs) have Status Deconfigured while nothing is Degraded/Faulted

Applies to:

Sun SPARC Enterprise M4000 Server - Version All Versions to All Versions [Release All Releases]
Sun SPARC Enterprise M5000 Server - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

On M4000/M5000 systems, cases have been observed where all major components as MBU_A, CPUM#[01]-CHIP#[01], MEMBs, and IOU#0 have been marked as Deconfigured in XSCF view, while nothing is Degraded or Faulty.

In such a scenario, platform domain(s) cannot boot. See the following excerpt from snapshot data:

*/*showhardconf.out : major Hardconf
*   MBU_A Status:Deconfigured; Ver:0101h; Serial:BC09070318 ;
*       CPUM#0-CHIP#0 Status:Deconfigured; Ver:0401h; Serial:PP090504J2 ;
*       CPUM#0-CHIP#1 Status:Deconfigured; Ver:0401h; Serial:PP090504J2 ;
*       CPUM#1-CHIP#0 Status:Deconfigured; Ver:0401h; Serial:PP090405BZ ;
*       CPUM#1-CHIP#1 Status:Deconfigured; Ver:0401h; Serial:PP090405BZ ;
*       CPUM#0-CHIP#0 Status:Deconfigured;                                  <<<
*       CPUM#0-CHIP#1 Status:Deconfigured;                                  <<< not
*       CPUM#1-CHIP#0 Status:Deconfigured;                                  <<< expected
*       CPUM#1-CHIP#1 Status:Deconfigured;                                  <<<
*       MEMB#0 Status:Deconfigured; Ver:0101h; Serial:BF09030GFX ;
*       MEMB#1 Status:Deconfigured; Ver:0101h; Serial:BF0850RBFG ;
*       DDC_A#0 Status:Deconfigured;
*       DDC_A#1 Status:Deconfigured;
*       DDC_B#0 Status:Deconfigured;
*   IOU#0 Status:Deconfigured; Ver:0101h; Serial:BF090512XG ;
*       DDC_A#0 Status:Deconfigured;
*       DDCR Status:Deconfigured;
*           DDC_B#0 Status:Deconfigured;
      XSCFU Status:Normal,Active; Ver:0101h; Serial:BF09030FH2 ;
      OPNL Status:Normal; Ver:0101h; Serial:BF090308AE ;

HW status is Deconfigured or Normal (nothing is Degraded/Faulty). Note that all CHIPs in CPUMs are listed twice in showhardconf output: this is not expected. The applied XCP version in the above case is XCP1081.

Changes

Cause

The reason for this strange output of 'showhardconf' is a corrupted Berkeley DataBase which in turn represents an invalid configuration and so all major components have Status:Deconfigured.
Analogue to this example the same scenario is also possible on an M5000 System.

Solution

To fix the issue power cycle the M4000, i.e. remove the power cords and plug them back. The XSCFU will restart.
Once it is restarted check 'showstatus' on the XSCF prompt and check that it is fine.

Upgrade Platform Firmware (aka XCP) to latest level is strongly recommended. Please check the following Documents for details about Mx000 Servers Firmware releases and information:
