Premigration Steps
Perform these steps to prepare for migration.
Zoning the Source EMC Storage to the Destination HP 3PAR StoreServ Storage System
The correct zoning must be present between the source EMC Storage system and destination
HP 3PAR StoreServ 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 EMC Storage system must be zoned to two peer ports on the destination HP 3PAR StoreServ Storage system. The peer ports on the destination HP 3PAR StoreServ Storage 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 HP 3PAR StoreServ 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 EMC Storage system and destination HP 3PAR StoreServ Storage system, ensuring that one EMC host port is in the same zone with one HP 3PAR peer port.
NOTE: The WWN of a host port changes when it is set to become a peer port. Use the new WWN of the peer port in zoning.
Each zone should contain only two ports: one from each storage system. Adjacent HP 3PAR peer nodes should be zoned to separate EMC controllers in a
