B Configuring the data path through MPX200 for iSCSI
online data migration
This appendix provides information on how to configure the data path through the MPX200 for
performing iSCSI to iSCSI and iSCSI to FC online data migration. It covers pre-insertion requirements,
the insertion process with Microsoft MPIO and Dell EqualLogic DSM.
NOTE:
MPX200 online migration with HP-UX hosts does not require you to change the initiator
type. Leave the initiator set to the default, Windows.

Pre-insertion requirements
Before inserting the router into the iSCSI host data path to the iSCSI storage array, ensure that the
host, MPIO, and initiator meet the following requirements:
•
The iSCSI host must have one dedicated subnet for iSCSI traffic.
•
The MPIO must be enabled on the iSCSI host. (On Windows 2008, MPIO is enabled by
default.)
•
Ensure that the Microsoft iSCSI initiator is installed on the iSCSI host. (On Windows 2008,
the initiator is already installed. For other OSs, download the iSCSI initiator from the Microsoft
Web site.
Insertion process with Microsoft MPIO
Follow these steps to insert the router iSCSI paths with the Microsoft MPIO:
1.
Using the Microsoft iSCSI initiator on the host machine, discover one of the iSCSI ports on
each of the router blades. This step creates initiator entrieson the blades. Ensure that the iSCSI
hosts have a logged-out status.
2.
Perform target presentation for the iSCSI target byissuing the targetmap addcommand, see
on the iSCSI portal. This step creates an iSCSI presented target. To
present the target, specify VPGROUP1.
The newly created iSCSI presentation has an IQN in the
formattarget_iqn.blade_serial_number.portal_index.
3.
Assign the iSCSI LUN to the iSCSI initiator by issuing the lunmask add command, see
