Mapping Initiators To Luns - HP StorageWorks MPX200 Solution Manual

3. (Optional) To discover the newly-presented LUNs and form the new arrays, if required, follow
these steps:
a. In the left pane of HP mpx Manager, click the Router tab.
b. Right-click the appropriate blade.
c. On the shortcut menu, click Rescan.
NOTE:
The HP MPX200 supports a maximum of four VPGs. To expose more than 255 LUNs from
any Fibre Channel storage array, you can enable additional VPGs in the HP MPX200
blades. To present up to 1,024 LUNs (4×256) from the same array to the HP MPX200,
repeat the preceding steps for each VPG.
After completing LUN and target presentation from the HP MPX200 to the server, follow
these recommended steps to insert the HP MPX200 in the data path and remove direct
access between the host and storage array. For operating system specific details, see
Appendix
4. Remove SA1 from Zone 1, and then validate the I/O failover to another path.
5. Activate Zone 9, and then validate the new path.
6. Remove SB1 from Zone 1, and then validate I/O failover to another path.
7. Activate Zone 10, and then validate the new path.
8. Remove SA2 from Zone 2, and then validate I/O failover to another path.
9. Activate Zone 11, and then validate the new path.
10. Remove SB2 from Zone 2, and then validate I/O failover to another path.
11. Activate Zone 12, and then validate the new path.

Mapping initiators to LUNs

HP mpx Manager provides the Target Presentation/LUN Mapping Wizard to map Fibre Channel
initiators to LUNs for online data migration. This mapping provides the access for the LUN to the host
from the router through a presented virtual target. Mapping is required as a part of the process of
inserting the router in the host I/O path. You must ensure that the entire host I/O is routed by the
router, and that there is no direct access to any source controller ports from the host during migration.
