8.1 Points of Concern During Expansion


8.1 Points of Concern During Expansion
Before expansion with the SPARC M12-2S, check the following items.
  1. If the SPARC M12-2S is mounted and used in a general rack, remove every SPARC M12-2S from the rack when moving to a different installation location. See "Safety precautions regarding racks" in "2.1 Safety Precautions."
  2. Before expansion with the SPARC M12-2S, save the system setting information using the dumpconfig command. To reset the configuration to the original settings, you can restore the saved setting information to the XSCF by using the restoreconfig command.
  3. Before expansion with the SPARC M12-2S, execute the showcodusage command to check the number of CPU Activations registered in the entire system.
    If the number of CPU Activations registered in the system is insufficient for the number of added CPU cores, a CPU Activation must be purchased. You will need to execute the addcodactivation command to add the CPU Activation key to the system. For details on adding a CPU Activation key, see "7.10.3 Registering a CPU Activation Key."
  4. Executing the addfru command for expansion automatically updates firmware to match firmware versions. The update matches the version on the master XSCF, so we recommend updating the XCP firmware on the master XSCF to the latest version in advance.
  5. To perform expansion with the SPARC M12-2S connected together with the PCI expansion unit and also set enable/disable for the direct I/O function of the PCI expansion unit, first execute the setpciboxdio command to set enable/disable. Then, execute the addboard command to incorporate them into a physical partition.
    When you have changed the setting of the direct I/O function, do not restart the logical domains until you execute the ldm add-spconfig command to save the logical domain configuration in the XSCF.
  6. To add the SPARC M12-2S with 64 GB DIMMs mounted, see "Notes on Memory" in the latest version of the Fujitsu SPARC M12 Product Notes.
  7. When adding the SPARC M12-2S, do not connect multiple units at a time but repeat the steps from executing the addfru command to the on-going addfru step to add one at a time.
  8. When the system configuration changes from a multiple-BB configuration to the 1BB configuration, the system setting information for each removed SPARC M12-2S will be cleared and reset to the factory defaults. Before removing the SPARC M12-2S, save the system setting information using the dumpconfig command. To reset the configuration to the original settings, you can restore the saved setting information to the XSCF by using the restoreconfig command.
  9. When expanding from 4BB (direct connection between chassis) to 8BB configuration, you need to newly install expansion rack 1.
    The master chassis will change from the SPARC M12-2S to the crossbar box mounted in the expansion rack. Before adding the expansion rack, the existing SPARC M12-2S need to be disconnected from the system.
    Multiple units cannot be disconnected from the system at the same time by the initbb command. Do this work one unit at a time.
  10. For the initialization of the SPARC M12-2S of the master XSCF, perform that work at the end. Execute the restoredefaults -c factory -r activation command to return to the factory defaults, including the CPU Activation key information. Perform this work with a serial connection to the master XSCF. The key must be reinstalled at initial setup of the XSCF after expansion.
  11. The serial number of the SPARC M12-2S of either the master XSCF or standby XSCF is used as the system serial number. If the serial number of the standby chassis is being used as the system serial number, the initbb command cannot release the standby SPARC M12-2S. In this case, execute the switchscf command to switch the master XSCF.
  12. When expanding from 8BB configuration to 9BB or a higher configuration, you need to newly install expansion rack 2. For details of expansion racks, see "2.4 Confirming Rack Specifications." In addition, special attention is required because crossbar cables need to be laid all over again.
Notes on use of dynamic reconfiguration (PPAR DR) for the physical partition
Note - When using the dynamic reconfiguration function for the physical partition (PPAR DR), check the contents of "2.5 Dynamic Reconfiguration Conditions and Settings" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide beforehand.
  1. When incorporating a PSB into a physical partition with the addboard command
    The PPAR DR function is enabled by default.
    The addboard command with the -c configure option specified cannot incorporate a PSB into a physical partition where the PPAR DR function is disabled.
