ports on the destination 3PAR storage system. See “Zoning the source EVA to the destination
3PAR storage system” (page 11).
• Paths must be zoned between the host and destination 3PAR storage system. The time at which
these paths are created is determined by the type of host—Windows or non-Windows. For
more information, see “Zoning a host to the destination 3PAR storage system” (page 12).
• Paths must exist between the host and source EVA. These paths will be unzoned during the
migration.

Zoning the source EVA to the destination 3PAR storage system
The correct zoning must be created between the source EVA storage system and destination 3PAR
storage system at every stage of the migration operation. The following zoning rules apply:
• There must be two unique paths between the source and destination storage systems. To create
two paths, the two controller host ports on the source EVA must be zoned to two peer ports
on the destination 3PAR. The peer ports on the destination 3PAR system must be on adjacent
nodes: 0/1, 2/3, 4/5, or 6/7.
• Zone the source and destination systems together and make sure they are visible to each other
before zoning hosts to the destination system.
• Do not unzone the source and destination systems from each other until the data migration is
complete.
To create the zoning:
1. On the destination 3PAR storage system, configure two free ports as peer ports using adjacent
node pairs: 0/1, 2/3, 4/5, or 6/7.
a. Set the Port connection type to point.
b. Set the Port connection mode to peer.
2. Create two zones between the source EVA storage system and destination 3PAR storage
system, ensuring that one EVA host port is in the same zone with one 3PAR peer port.
Each zone should contain only two ports: one from each storage system. Adjacent 3PAR peer
nodes should be zoned to separate EVA controllers in a one-to-one mapping. For example,
zone the peer port on node 0 on the 3PAR storage system to controller A on the EVA, and
zone the peer port on node 1 on the 3PAR storage system to controller B on the EVA.
