Using the MPX200 Target Map feature, new Presented Target WWPN’s are created for each
source array port.

During the online migration process the server is zoned with these new Presented Targets to access
the LUNs through the MPX200.
Global presentation
When more than 256 LUNs from a single storage array are mapped to a server, you must present
these LUNs across multiple VPGs. Each VPG on the MPX200 can see 256 LUNs.
To reduce the number of steps required to create presented targets that represent the same target
ports across multiple VPGs, the MPX200 allows you to create a global presented target that spans
all virtual port groups (VPG1, VPG2, VPG3, and VPG4). If you need to map a source array target
port across more than one VPG, HP recommends that you create a global presented target in the
Target Map Wizard.
Global presentation of targets spans all VPGs, and does target mapping for both FC and iSCSI
ports. Global presentation, like virtual presentation, is common for all VPGs. A single source array’s
target port can have a single global and virtual presentation that functions for all VPGs.
