1.
Configure the hosts as follows:
Host 1:
1.
Present LUNs A, B, and C to the host as LUN IDs 1, 2, and 3.
2.
Present LUNs A, B, and C to the MPX200 VPG1 as LUNs 1, 2, and 3.
Host 2:
1.
Present LUNs D, E, and F to the host as LUN ID 5, 6, and 7.
2.
Present LUNs D, E, and F to the MPX200 VPG1 as LUN 5, 6, and 7.
Host 3:
1.
Present LUNs G, H, and I to the host as LUN ID 1, 2, and 3.
2.
Present LUNs G, H, and I to the MPX200 VPG2 as LUN ID 1, 2, and 3.
This configuration enables MPX200 VPG1 and VPG2 to see all four source array target ports
through both blades.
2.
Create the following presented targets when presenting the LUNs to Host 1 or Host 2:
•
PT2 is SA2+VPG1
•
PT2 is SA2+VPG1
•
PT3 is SB1+VPG1
•
PT4 is SB1+VPG1
3.
Create the following additional presented targets when presenting LUNs to Host 3:
•
PT4 is SA1+VPG2
•
PT5 is SA2+VPG2
•
PT6 is SB1+VPG2
•
PT7 is SB1+VPG2
Step 3: Zone in presented targets with initiator ports
Zone in appropriate presented targets with initiator ports on the server. After completing LUN and
target presentation from the MPX200 to the server, follow these recommended steps to insert the
MPX200 in the data path and remove direct access between the host and storage array. Depending
on the source array type (active-active or active-passive) and configuration (cluster or noncluster),
these steps may vary.
NOTE:
For information about online insertion of the MPX200 in the data path in a cluster
configuration, see the HP application note, MPX200 Data Migration for Cluster Configurations.
You can use either one of the methods in this section for single server configuration. In addition,
refer to the following:

for online data migration” (page 152)
Zoning in presented targets: Method 1
Source array: active-passive or active-active
Single server configuration: noncluster
This method represents a conservative approach. In this method, you remove one direct path from
the source array, and then enable an equivalent path from the MPX200. This method requires
multiple zoning steps:
1.
Remove SA1 from Zone 1, and then validate the I/O failover to another path.
