You can set the path definition for external LUs (add, delete, or change paths). ◦
◦ You can set the command devices on external LUs (add or delete the setting).
◦ CHIP mode, host group, and WWN settings for external ports are not supported. When
an external LU is mapped through that external port, the topology setting is not available.
NOTE: Some mainframe products might be marketed under different HP names and are not
supported at this time. Contact your HP account support representative for the latest support matrix.
Using external LUs for XP Auto LUN operations
Figure 14 (page 40) shows an example of using an external LU for XP Auto LUN operations. The
mapped external LU is set as the source volume, and the local array internal LDEV is set as the
target volume. Existing data in the external LU is (in effect) manually migrated to the internal LDEV
on the local array using XP Auto LUN. For more information, see the HP XP LUN Configuration
and Security Manager user guide: HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200
Storage Virtualization System.
Figure 14 Example of XP Auto LUN operations
1. Use XP External Storage to map a volume in the external array to an internal LDEV of the local
array.
For this example, set the following attributes for the mapped LU:
•
Emulation type: OPEN-V
•
IO Suppression mode: Disable
For more information, see Mapping external LUs (Add LU) .
CAUTION: To migrate existing data in the mapped external LU to a local array volume using
XP Auto LUN or XP Business Copy, as shown in Figure 14 (page 40) , set the local array's
emulation type to OPEN-V when mapping the LU. Only OPEN-V emulation can be used to
read existing data in the external LU from the local array side.
To copy existing data in the mapped external LU using HP software products, such as XP
Continuous Access and XP Business Copy, the mapped external LU's emulation type must also
be OPEN-V.
