11.2.4 Checking the Memory Mirror Mode Settings
Use the showfru command to check the memory mirror mode settings. You can check the following content with respect to a PSB used to configure a physical partition.
  1. Device
    sb: You can check the BB (PSB).
    Example: 00-0: PSB of BB-ID 0

    cpu: You can check the CPU mounted on the BB.
    Example: 00-0-2: CPU#2 on the PSB of BB-ID 0
  2. Memory mirror mode
    You can check the status of the memory mirror mode settings, which can be set for each CPU.
    yes: Memory mirror mode
    no: Non memory mirror mode
Note - For the settings/details of memory mirror mode, see "Chapter 14 Configuring a Highly Reliable System."
Operation Procedure
  1. Execute the showfru command to check device information.
    The following example displays the set information for all devices.
XSCF> showfru -a
Device Location Memory Mirror Mode
sb 00-0
cpu 00-0-0 yes
cpu 00-0-1 yes
cpu 00-0-2 yes
cpu 00-0-3 yes
sb 01-0
cpu 01-0-0 yes
cpu 01-0-1 yes
cpu 01-0-2 yes
cpu 01-0-3 yes
sb 02-0
cpu 02-0-0 no
cpu 02-0-1 no
cpu 02-0-2 no
cpu 02-0-3 no
sb 03-0
cpu 03-0-0 yes
cpu 03-0-1 yes
cpu 03-0-2 no
cpu 03-0-3 no

  1. The following example specifies the sb operand to display the set information for the specific PSB.
XSCF> showfru sb 01-0
Device Location Memory Mirror Mode
sb 01-0
cpu 01-0-0 yes
cpu 01-0-1 yes
cpu 01-0-2 yes
cpu 01-0-3 yes
  1. The following example specifies the cpu operand to display the set information for the specific CPU.
XSCF> showfru cpu 01-0-3
Device Location Memory Mirror Mode
sb 01-0
cpu 01-0-3 yes
