Reactivating the original vFiler unit by using vfiler dr commands

If the storage system is severely damaged, or you are not familiar with using SnapMirror commands, you can reactivate the vFiler unit by using vfiler dr commands.

Steps

  1. Boot the original storage system and interrupt the boot process by pressing the Del or Esc key while the memory self-test is in progress.

    Note: If you do not press the Del or Esc key in time, you can press Ctrl-C when prompted later during the boot, choose option 5 (maintenance mode), and enter halt.

  2. At the loader prompt, set the no-vfiler-ips? parameter as follows:
    setenv no-vfiler-ips? true

    This ensures that the storage system does not try to bind IP addresses already being used by the disaster recovery vFiler unit.

  3. At the loader prompt, enter the boot command.
  4. To destroy the original vFiler unit, enter the following command on the original storage system:
    vfiler destroy vfilername

    vfilername is the name of the original vFiler unit.

  5. Stop the disaster recovery vFiler unit by using the vfiler stop command.
  6. Create the disaster recovery vFiler unit.
  7. Update the data on the original storage system.

    For each volume and qtree owned by the new vFiler unit, enter the following commands on the original storage system (or its replacement) to update the data:

    snapmirror break name
    snapmirror resync -S disaster_recovery_filer:name production_filer:name

    disaster_recovery_filer is the name of the disaster recovery storage system.

    production_filer is the name of the original storage system.

    name is the volume name or path name of the qtree.

    Example

    For the volume vol1, enter the following commands:

    snapmirror break drfiler:vol1
    snapmirror resync -S drfiler:vol1 prfiler:vol1

    Example

    For the qtree qtree1, enter the following commands:

    snapmirror break drfiler:/vol/vol2/qtree1
    snapmirror resync -S drfiler:/vol/vol2/qtree1 prfiler:/vol/vol2/qtree1

  8. Create a new vFiler unit on the original storage system (or its replacement).

    The original vFiler unit is now reactivated on the original storage system or its replacement.

  9. Reinstate the disaster recovery vFiler unit on the disaster recovery storage system:
    If the storage elements for the vFiler unit are... Then...
    Volumes On the disaster recovery storage system, enter the following command:
    vfiler dr resync [-l authinfo] [-a alt-remote, alt-local] [-c secure] [-s] original_vfilername@original_filer
    Qtrees
