Arrays or the HP XP Remote Web Console user guide for XP12000/XP10000 Disk Arrays
and SVS 200.
2. Click the XP External Storage button ( ). XP External Storage starts.
3. Cancel any existing Flex Copy pairs. For instructions, see the HP Flex Copy XP user guide.
4. Delete any external LU mapping. For instructions, see Deleting external LU mappings (Delete

6. For the local array, use the XP Command View Advanced Edition Software or Remote Web
Console Licensing module to remove the XP External Storage license key. For instructions, see

Limitations on XP External Storage operations
•
External LUs can be mapped as any CU:LDEV combination from 00:00 to 3F:FF.
•
Only ports in SLPR0 can be set as external ports.
•
Before mapping external LUs, make sure that external LUs are not reserved by a host.
External LUs that are reserved by a host cannot be mapped as internal LDEVs. If external LUs
are reserved by a host, cancel the reserve settings and then map the external LUs.
•
Do not reserve mapped external LUs for a host.
Internal LDEVs, to which external LUs are mapped, will be blocked if the mapped external LUs
are reserved by a host.
•
Do not access any external storage volume that is mapped as an XP External Storage volume
from a host connected directly to the external array. Also, do not access an XP External Storage
mapped external array volume using the external array's functions (for example, local
replication). After mapping an external disk volume as a local array volume, access the
mapped external disk volume only via the local array.
•
Except on the MSA, a host can directly access external array volumes that have not been
mapped as local array volumes.
•
XP Continuous Access P-VOLs, S-VOLs, and journal volumes are not supported on MSA arrays.
•
HP does not recommend that volumes involved with XP Snapshot reside on external MSA
arrays.
•
When an external array that has an ownership is connected to XP12000 Disk Array, configure
the path to the primary controller in the external array as primary path.
Ownership is an exclusive right to control volumes. A controller that has an ownership is called
a primary controller. If a path to a controller without ownership is configured as primary path,
the ownership will be transferred and it may affect the performance.
