You must set the IO Suppression mode to Disable to use the mapped external LU for Volume Retention
Manager operations.
• LUN Security XP Extension
• You must set the IO Suppression mode to Disable to use the mapped external LU for LUN
Security XP Extension operations.
• If you previously mapped the external LU and set the VMA of LUN Security XP Extension in
that volume, the previous VMA setting is overwritten when you map the LU again. However, if
LUN Security XP Extension is not installed when you remap the LU, you cannot map the
LU with the VMA setting.
• SNMP
Information about the mapped external LU and external port is displayed.
• Configuration File Loader
• 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).
• CHA 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 Auto LUN XP operations
Figure 14 shows an example of using an external LU for Auto LUN XP 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 Auto LUN XP. For more information, see the HP StorageWorks Auto LUN XP user guide for the
XP12000/XP10000/SVS200.
Figure 14 Example of Auto LUN XP operations

Use External Storage XP 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
