HP 3PAR Online Import for EMC Storage Data Migration Guide

Update Host Multipath Software and Unzone from Source EMC Storage System
CAUTION: PowerPath must NOT be installed during the migration process. Native MPIO must
be managing the paths.
CAUTION: Stop all applications before removing PowerPath. Applications should be restarted
after migration is started.
1. Perform the following steps on the Windows host:
a. Remove EMC PowerPath Multipath software from host following the PowerPath
documentation instructions. After removal, you will be prompted to restart the host in
order for the changes to take effect. Do NOT restart at this point.
b. The removal of PowerPath may have also disabled the MPIO installation but not removed
it. Manually check to see if MPIO is still loaded, and if it is, fully remove it at this time.
Now, restart the host.
c. Zone the host to the destination HP 3PAR StoreServ Storage system to establish
communication. Validate Host to Destination connectivity using the 3PAR Management
Tool by confirming host initiator login on the 3PAR.
d. Configure MPIO multipath software on the host.
1. Install MPIO.
2. Register 3PAR LUN types with MPIO by configuring MPIO to use 3PARdataVV as
the device hardware ID.
NOTE: 3PARdataVV is case sensitive.
NOTE: You will be prompted to reboot the host in order for the change to take effect.
Do NOT reboot at this point as this procedure will already require stopping and restarting
the Windows host immediately in the next step.
e. Shutdown the Windows host. Leave the host offline until the migration is started.
2. Unzone the source EMC Storage system from the host.
