7–Using the HP MSA2012fc Storage Array
Workaround for Using a Single Array License for MSA2012fc
7-2 ISR654606-00 A
MSA2012fc allows a maximum of 128 volumes (LUNs) to be accessed through
one controller from any host. If you need to migrate data to and from more than
128 LUNs, you must present LUNs in batches with a maximum of 128 LUNs at a
time.
To unpresent old LUNs and present new LUNs to the MPX200 ports, follow the
steps in “Reconfiguring LUNs on a Storage Array” on page 8-1.
Workaround for Using a Single Array License for
MSA2012fc
In order to use a single license for an MSA2012fc array where data needs to be
migrated to and from LUNs owned by both ControllerA and ControllerB, use the
following workaround.
To use a single array license for MSA2012fc:
1. Add array-based licenses (a Single Array or Three Array License) as
required.
2. Present LUNs that need to be used by data migration jobs from the storage
array to the MPX200 ports.
3. Make sure that the LUNs are presented with the same LUN ID for both
MPX200 ports.
4. Zone in only ControllerA ports with the MPX200. The MPX200 will create
one array entity for the zoned in ports, because they belong to the same
controller.
5. Apply array-based licenses to the array entity using the set array CLI
command, or in the License Array dialog box.
6. Configure data migration jobs as described in “Scheduling an Individual
Data Migration Job in the GUI” on page 3-8 or “Scheduling Data Migration
Jobs in Batch Mode” on page 3-15.
7. After the data migration jobs for all the LUNs belonging to ControllerA are
completed and acknowledged, perform a reconfiguration.
8. Zone out the MSA2012fc ports and the MPX200 ports.
9. Unpresent the LUNs presented in Step 2.
10. Change the ownership of LUNs from ControllerB to ControllerA for all the
LUNs that belong to Controller B and need to be used in data migration jobs.
11. Present LUNs from Step 10 from the storage array to the MPX200 ports.
12. Make sure that the LUNs are presented with the same LUN ID for both
MPX200 ports.
