HP XP External Storage Software - Manual (Page 31)

HP StorageWorks XP Snapshot Software
Mapped volumes can be used for XP Snapshot. Consider the following for XP Snapshot:
•
Both internal and external volumes cannot be mixed in one pool.
•
All external volumes in the same pool must be in the same Cache Mode.
HP StorageWorks XP Thin Provisioning Software
Mapped volumes can be used for XP Thin Provisioning. Consider the following for XP Thin
Provisioning:
•
Both internal and external volumes cannot be mixed in one pool.
•
All external volumes in the same pool must be in the same Cache Mode.
SNMP Agent
Consider the following for SNMP Agent:
•
The information on the mapped external volume is displayed.
•
The information on the external port is displayed.

XP Auto LUN Operations
Figure 14 (page 32) shows the use of an external volume for the XP Auto LUN operation. The
mapped external volume is set as the source volume and the local internal volume is set as the
target volume. Existing data in the external volume is migrated manually to the local storage system
internal volume using XP Auto LUN. For detailed information on XP Auto LUN operations, see the
HP StorageWorks XP24000/XP20000 Auto LUN Software User Guide.
The procedure for the operation is as follows:
1. Use XP External Storage to map a volume in the external storage system as an internal volume
of the local storage system.
For Figure 14 (page 32) , set the attributes of the mapped volume as follows:
Emulation type: OPEN-V
To migrate the existing data in the mapped external volume to the local storage system volume
using XP Auto LUN, set the emulation type to OPEN-V as you map the volume. The emulation
type must be OPEN-V to read out the existing data in the external volume from the local storage
system side.
