Complete this task to perform Global Copy failback processing for
the A volumes. This process resynchronizes the volumes at Site A with volumes
at Site B and restarts mirroring from site A (local site) to site B (remote
site). This is the sixth step in the failback recovery process.
The failover processing that is described in the fifth step of the
failback recovery process must have completed. The failover process converted
the full-duplex target volumes at site A to suspended source volumes. The
volumes at site A started the change recording process while in failover mode.
The failback processing that is described in this task can be issued
against any remote mirror and copy volume that is in a primary suspended state.
The failback processing copies the required data from the source volume to
the target volume in order to resume mirroring.
Perform the following step
to complete failback processing for the A volumes. The example commands in
this task are shown in two formats. The first format shows the type of information
that is required by the command. The second format provides the command with
declared values for the variables.
Issue the failbackpprc command to resynchronize your volumes.
Enter the failbackpprc command at the dscli command prompt with the
following parameters and variables: dscli>failbackpprc -dev storage_image_ID -remotedev storage_image_ID
-type gcp SourceVolume_ID:TargetVolume_ID
Example
dscli>failbackpprc -dev IBM.1750–68FA120 -remotedev IBM.1750–68FA150
-type gcp 1000:1000
Notes: - The -dev parameter specifies the ID of your source storage unit.
Your source is the Site A storage unit.
- The -remotedev parameter specifies the ID of the target storage
unit. The remote storage unit is your Site B storage unit.
- The SourceVolume_ID:TargetVolume_ID value has the Site A
volume ID as the source and the Site B volume ID as the target.
