Prerequisite Component Installation
1. Check the Single Point of Connectivity Knowledge (SPOCK) website to confirm proper
configuration.
“Configuration Rules for HP 3PAR Online Import for EMC Storage Support” (page 9)
2. Install EMC SMI–S Provider

Zoning the Source EMC to the Destination HP 3PAR StoreServ Storage
System
The correct zoning must be created 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 3PAR peer
port.
Each zone should contain only two ports: one from each storage system. Adjacent 3PAR peer
nodes should be zoned to separate EMC controllers in a one-to-one mapping. For example,
zone the peer port on node 0 on the HP 3PAR StoreServ Storage system to controller A on
the EMC, and zone the peer port on node 1 on the HP 3PAR StoreServ Storage system to
controller B on the EMC Storage system.
3. Verify that the EMC can detect both ports on the 3PAR.
Ensure that the peer port WWNs appear in the discovered port list. Alternately, verify that
the EMC is shown as a connected device on both peer ports of the destination HP 3PAR
StoreServ Storage system.
