HP 3PAR Peer Motion Guide

Figure 4 Import stage
In this Import stage, migration can start. The host accesses the volumes on the source array
via the destination array. Host issued Reads and Writes may see increased latency.
For Host Level Migration, the hosts are prevented from directly accessing the volumes on the
source array by manually removing the zones for those paths.
For Single Volume Migration, the hosts are prevented from directly accessing the volumes on
the source array by an automatic peer motion re-configuration of those paths from active to
standby.
