HP 3PAR Online Import for EMC Storage Data Migration Guide

IMPORTANT: If you unzone the host and EMC Storage system but don't reconfigure the host
DSM, the host/cluster will experience an outage because it will not be able to communicate with
the destination HP 3PAR StoreServ Storage system.
Network and Fabric Zoning Requirements
Data migration requires the necessary zoning to create paths between the source and destination
storage systems and any hosts involved in the migration. The data paths used are shown in
Figure 1 (page 25).
• Two unique paths must be zoned between the source and destination storage systems. To
create two paths, the two controller ports on the source EMC Storage system must be connected
to two peer ports on the destination HP 3PAR StoreServ Storage system. See “Zoning the
Source EMC to the Destination HP 3PAR StoreServ Storage System” (page 26).
• Paths must be zoned between the host and destination HP 3PAR StoreServ Storage system.
The time at which these paths are created is determined by the type of host—Windows or
Linux.
• Paths must exist between the host and source EMC Storage system. These paths will be unzoned
during the migration.
