HP 3PAR Peer Motion Guide

Figure 3 Admit stage
• In the Admit stage, the volumes to be migrated are admitted to the destination array. These
admitted volumes appear as volumes in the HP 3PAR Management Console for the destination
array with ‘peer’ for their Provisioning type. In this stage, the volumes are defined and prepared
on the destination array for export to the Host. No local storage is allocated for these volumes
on the destination array at this point in time.
• The multi-pathing software on the Host sees four paths to the same volume. Appropriate SCSI
rescan/multi-pathing configuration must be performed on the Host to pick up the additional
paths from the destination system.
