Presenting Luns To The Server For Online Data Migration - HP StorageWorks MPX200 Solution Manual

4. Log into the iSCSI target by issuing the iscsi login command (see
NOTE:
If the iSCSI storage array supports it, you can establish multiple connections per session
using multiple GbE ports on the same router blade and storage array.
5. Register the router as a host using the iSCSI qualified name (IQN) of the iSCSI port, and then
assign LUNs to this host.
NOTE:
Some iSCSI arrays require pre-registered hosts for the iscsi discover command to
succeed. For these arrays, manually create a host with the IQN of the router iSCSI port
before you issue the command.
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.

Presenting LUNs to the server for online data migration

For online data migration, you need to create access to all LUNs associated with the server or servers
through the router, and you must eliminate direct access from the server to the storage array.
NOTE:
Live insertion of the HP MPX200 in the data path for cluster configuration is not currently supported.
To present source array LUNs to the server for online DMS:
1. In HP mpx Manager, use the Target Presentation/LUN Mapping Wizard to automatically detect
the portal on which the target is discovered and to create a presented target on these portals.
See "Mapping initiators to
Because SANsurfer Router Manager performs an array-based LUN presentation, the LUN is
presented to an initiator through all of the discovered target ports. The visibility of a LUN through
a target on the initiator depends on your zoning configuration.
2. In the CLI, issue the lunmask add command (see "lunmask" on page 105) and select the
appropriate target and portal. For example:
HBA1 > SA1 > LUN1 > BL1 FC1 VPG1 creates presented target PT-SA1
HBA2 > SB2 > LUN1 > BL2 FC2 VPG1 creates presented target PT-SB2
