10.10.1 Understanding How to Save/Restore XSCF Settings Information
This section describes the following two methods of saving/restoring XSCF settings information.
  1. Save/Restore the setting information locally by connecting a USB device to one of the USB ports mounted on the XSCF unit panel (rear panel) of the master XSCF.
  2. Transfer data to the network host via the network. The data transfer at this time uses an encryption protocol.
Note - When replacing the XSCF unit of the SPARC M12-2/M12-2S, the XSCF settings information can be taken over by also swapping the SD card. When replacing the crossbar box (XBBOX) or CPU memory unit (lower) (CMUL) of the SPARC M10-4/M10-4S, the XSCF settings information can be taken over by also swapping the microSD card.
For details, see the section "Replacing the SD card" or "Replacing microSD card" in the Service Manual for your server. When replacing the XSCF unit of a crossbar box, see "8.5  Switching the microSD Card" in the Crossbar Box for Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Service Manual.
Purposes of Saving
The purposes of saving XSCF settings information with the dumpconfig command are as follows.
  1. Backing up the setting information enables the data to be restored after a failure.
  2. Copying the master XSCF settings information allows the same setting information to be used by the XSCFs of other servers.
Notes on Saving and Restoration
  1. USB devices need to be formatted with the FAT32 file system. For the capacity of the USB device used to save/restore the setting information locally and for points to note about handling, ask a service engineer.
  2. This setting information can be restored on only the same model where the setting information was saved. For example, the setting information saved on a SPARC M10-1 system can be restored on only a SPARC M10-1 system. To restore data, consistency between the configuration file of the current system and the configuration file being restored is checked. The file is restored only when the configuration file versions, system names, and other information can be confirmed to be consistent. Note that the configuration file version does not depend on the XCP version. The configuration files may be different versions even when the XCP versions are the same at the save/restore time.
  3. The systems with multiple XSCFs save/restore the data on the master XSCF side.
  4. The dumpconfig command can be used with specified options to encrypt saved data. You can safely restore the encrypted data by entering the key specified at the save time and executing the restoreconfig command.
  5. The following identification information is added to the beginning of a saved configuration file. You can refer to the identification information in the text.
    - User comment

    - Data version

    - Whether encryption is enabled or disabled

    - Save time

    - System name

    - Serial number

    - XCP version
  6. The XSCF network settings specify options to restore data.
  7. To restore the setting information, power off all physical partitions. Additionally, when the restore command is executed, the XSCF settings information is loaded, so the correctness of its content can be checked. Once the confirmation is complete, the XSCF is rebooted and the data is restored.
