6.4 Diagnosing a Replacement FRU


6.4 Diagnosing a Replacement FRU
This section describes the diagnosis function for checking whether a replacement FRU is operating normally. For details on the commands, see the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual of the XCP firmware version used.
  1. Log in to the XSCF shell.
  2. Execute the testsb command.
    The testsb command is used to perform an initial diagnosis of the specified physical system board (PSB). The PSB is powered on and off during the diagnosis. You can check the mounting of HDDs, SSDs, and PCIe cards by specifying options.
  1. In the following example, an initial diagnosis of a PSB and a check of the connected I/O are performed.

    <‌Description of options>‌
    -v: Additionally displays a detailed message from the initial diagnosis.

    -p: During diagnosis processing, executes the "probe-scsi-all" command of the OpenBoot PROM and displays the result.

    -s: During diagnosis processing, executes the "show-devs" command of the OpenBoot PROM and displays the result.

    -a: Diagnoses all the mounted PSBs.

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

00-0 Passed Normal
  1. From the execution result of "probe-scsi-all", confirm that the mounted HDDs/SSDs are recognized.
  2. From the execution result of "show-devs", confirm that the mounted PCIe cards are recognized.
  3. From the execution result of the initial diagnosis, confirm that "Passed" and "Normal" are displayed for all the PSBs.
