I.3.6 Restoring the GFS Configuration Information

Restore the GFS configuration information to the copy destination servers.

Note

This procedure is required when using a GFS Shared File System on the copy source servers.

  1. Reinitialize the management partition on the one node of the copy destination servers.

    Example: Initializing the /dev/sfdsk/gfs/rdsk/control file as the management partition.

    # sfcsetup -cf /dev/sfdsk/gfs/rdsk/control
  2. Reregister the information of the configuration node on each node.

    # sfcsetup -a /dev/sfdsk/gfs/rdsk/control
  3. On the one node of the copy destination servers, redo the settings for the startup method of the sfcfrmd daemon as recorded in "Backup of the configuration information of GFS" in Step 3.

    Example: For setting the startup method of sfcfrmd daemon to wait_bg

    # sfcsetup -m wait_bg

    Note

    This procedure is required when changing the startup method of the sfcfrmd daemon from the default value wait.

  4. Confirm that the management partition is reinitialized.

    The path name of the management partition for which the settings were made can be confirmed by executing the "sfcsetup(1M)" command with the -p option.

    # sfcsetup -p
    /dev/sfdsk/gfs/rdsk/control

    The registered node information can be confirmed by executing the "sfcsetup(1M)" command without any option.

    # sfcsetup
    HOSTID          CIPNAME         MP_PATH
    80380000        fuji4RMS        yes
    80380001        fuji5RMS        yes

    The startup method of the sfcfrmd daemon can be confirmed by executing the"sfcsetup(1M)" command with the -m option.

    # sfcsetup -m
    wait_bg
  5. Start the sfcfrmd daemon by executing the following command on all nodes.

    # sfcfrmstart
  6. Set the GFS Shared File System.

    • Without copying the data on the shared disk

      Create the GFS Shared File System.

      See

      For details on how to create a GFS Shared File System, see "Creating a file system" and "Selecting a communication protocol" of "Creation" of "File System Operations (Command)" in "PRIMECLUSTER Global File Services Configuration and Administration Guide."

    • Copying the data on the shared disk

      Restore the information of the management partition.

      Execute the shell script edited in "I.1.1 Backing up the GFS Configuration Information" on any one node.

      # sh _backup_file_
      get other node information start ... end

      Confirm that restoration of the management partition of GFS was successful by running the "sfcinfo(1M)" command and the "sfcrscinfo(1M)" command.

      # sfcinfo -a
      /dev/sfdsk/gfs01/dsk/volume01:
      FSID special size Type mount
      1 /dev/sfdsk/gfs01/dsk/volume01(15000000021) 14422 META -----
      1 /dev/sfdsk/gfs01/dsk/volume01(15000000021) 5116 LOG -----
      1 /dev/sfdsk/gfs01/dsk/volume01(15000000021) 95112 DATA -----
      # sfcrscinfo -m -a
      /dev/sfdsk/gfs01/dsk/volume01:
      FSID MDS/AC STATE S-STATE RID-1 RID-2 RID-N hostname
      1 MDS(P) stop - 0 0 0 host4
      1 AC stop - 0 0 0 host4
      1 MDS(S) stop - 0 0 0 host5
      1 AC stop - 0 0 0 host5
  7. Mount the GFS Shared File System on all nodes.

    # sfcmntgl <mount point>
