ANTP0001I CQUERY COMMAND COMPLETED FOR DEVICE 6430. COMPLETION CODE: 00
Both devices are in suspend state. Note that for device 6430, the direction of the Metro Mirror
pairing has been reversed. Because the volume is in suspend state, changes will be recorded
by the DS6000. At this stage you could start running your application at the secondary site.
16.2.2 Failback process
The high level failback process in a planned scenario is as follows:
1. Quiesce the applications at the recovery site.
2. Use Metro Mirror establish path commands to create paths from the recovery site to the
primary site (remember, paths are required for all LSS pairs).
3. Issue Metro Mirror establish pair commands to the B volume, specifying the Failback
action and reversing the original PRIM and SEC parameters. This copies any changes
