Reactivating the original vFiler unit using vFiler dr commands

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 don't press the Del or Esc key in time, you can press Ctrl-C when prompted later during the boot; then choose option 5 (maintenance mode); then enter halt.

At the OK prompt, set the no-vfiler-ips? variable 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.

At the OK prompt, enter boot.

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.

Follow the procedure for Creating a replacement vFiler unit on the original storage system or its replacement.

Stop the disaster-recovery vFiler unit by using the vfiler stop command.

Prepare for the new vFiler unit on the original (or its replacement) storage system:

Perform the preparation steps in Preparing the destination storage system.

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 (or its replacement) storage system:

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 1

For volume vol1, enter the following commands:

snapmirror break drfiler:vol1

snapmirror resync -S drfiler:vol1 prfiler:vol1

Example 2

For qtree qtree1, enter the following commands:

snapmirror break drfiler:/vol/vol2/qtree1

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

Create the new vFiler unit on the original (or its replacement) storage system, following directions under Creating the vFiler unit.

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

Reinstate the disaster-recovery vFiler unit on the disaster-recovery storage system.

local] [-s] original_vfilername@original_filer 

For details of the vfiler dr resync command, see Step 2 of Resynchronizing the original vFiler unit.

You are done.

The storage elements for the vFiler unit are qtrees
