Lun Presentation From Iscsi Arrays - HP StorageWorks MPX200 Solution Manual

To present source and destination LUNs from Fibre Channel arrays:
1. Zone in source array controller ports with HP MPX200 Fibre Channel ports. Refer to the
appropriate topology shown in
2. Create and activate Zone 3 and Zone 4 such that each router blade can access all ports on
source array controllers A and B.
3. Zone in destination array controller ports with HP MPX200 Fibre Channel ports. Refer to the
appropriate topology shown in
4. Create and activate Zone 5 and Zone 6 such that each router blade can access all ports on
destination array controllers A and B.
5. Present LUNs from both the source and destination array to the HP MPX200 as follows:
a. Register the following router Fibre Channel WWPNs from the same virtual port group (VPG)
as a single "host entry" in the storage array:
• BL1–FC1–VPG1
• BL1–FC2–VPG1
• BL2–FC1–VPG1
• BL2–FC2–VPG1
b. Present the LUNs (associated with the server) to the router as the same LUN ID (if possible)
as presented to the server. If multiple servers are being migrated at the same time using the
same HP MPX200, and different LUNs are presented to the different server as the same LUN
ID, you must use VPG that is different from the router.
6. (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.

LUN presentation from iSCSI arrays

This section provides the procedures for presenting LUNs and discovering iSCSI storage arrays for
offline data migration.
To present source and destination LUNs from iSCSI arrays:
1. Determine the iSCSI initiator name of each blade by issuing the show iscsi command (see
"show iscsi" on page 143).
2. Using the CLI, discover iSCSI storage arrays by issuing the iscsi discover command (see
"iscsi discover" on page 103).
3. List the discovered iSCSI targets, as well any Fibre Channel targets (if present), by issuing the
show targets command (see
38 Using DMS for data migration
"Supported topologies" on page 19.
"Supported topologies" on page 19.
"show targets" on page 141).
