3.1.11 Setting Memory Mirroring


3.1.11 Setting Memory Mirroring
Use the setupfru command to set memory mirroring.
Note - A user account that has the platadm or fieldeng privilege can execute the setupfru command.
- For SPARC M12
Specify -c mirror=yes to create a mirroring configuration for the memory in SPARC M12.
XSCF> setupfru [[-q] -{y|n}] -c function=mode device location
- For SPARC M10
Specify -m y to create a mirroring configuration for the memory in SPARC M10. The -c mirror option cannot be used.
XSCF> setupfru [-m {y|n}] device location
  1. -c function=mode

    Specify whether to set the memory to mirror mode. To set it to mirror mode, specify -c mirror=yes. Otherwise, specify -c mirror=no. Can only be used in SPARC M12.
  2. -m {y|n}

    Specify whether to set the memory to mirror mode. To set it to mirror mode, specify y. Otherwise, specify n. If the -m option is omitted, the previous setting is inherited.
  3. device
    Specify the range to set for mirror mode. If sb is specified, the command reflects the setting on all the CPUs under the specified PSB. If cpu is specified, the command reflects the setting on only the specified CPU.
  4. location
    If the device name is sb, specify a PSB number. The format is BB-ID-0. If the device name is cpu, specify a CPU. The format is BB-ID-0-CPU. Here, BB-ID is an integer ranging from 0 to 15, and CPU is an integer ranging from 0 to 3.
The following example sets all the CPUs under BB#01 (PSB#01) to memory mirror mode in SPARC M12.
XSCF> setupfru -c mirror=yes sb 01-0

Notice:
- Logical domain config_name will be set to "factory-default".


Memory mirror mode setting will be changed, Continue? [y|n] :y
The following example sets CPU1 under BB#02 to memory mirror mode in the SPARC M12.
XSCF> setupfru -c mirror=yes cpu 02-0-1


Notice:
- Logical domain config_name will be set to "factory-default".


Memory mirror mode setting will be changed, Continue? [y|n] :y
Note - If you use SPARC M10, specify the following:
XSCF> setupfru -m y device location
