5–Performing Data Migration
Mapping Initiators to LUNs
ISR654608-00 B 5-7
After completing LUN and target presentation from the iSR6200 to the
server, follow these recommended steps to insert the iSR6200 in the data
path and remove direct access between the host and storage array. For
operating system specific details, refer to
Appendix A Configuring the Data
Path Through iSR6200 for Online Data Migration .
3. Remove SA1 from Zone 1, and then validate the I/O failover to another path.
4. Activate Zone 9, and then validate the new path.
5. Remove SB1 from Zone 1, and then validate I/O failover to another path.
6. Activate Zone 10, and then validate the new path.
7. Remove SA2 from Zone 2, and then validate I/O failover to another path.
8. Activate Zone 11, and then validate the new path.
9. Remove SB2 from Zone 2, and then validate I/O failover to another path.
10. Activate Zone 12, and then validate the new path.
Mapping Initiators to LUNs
SANsurfer iSCSI/FC Router Manager provides the Target Presentation/LUN
Mapping Wizard to map Fibre Channel initiators to LUNs for online data migration.
This mapping provides the access for the LUN to the host from the router through
a presented virtual target. Mapping is required as a part of the process of inserting
the router in the host I/O path. You must ensure that the entire host I/O is routed
by the router, and that there is no direct access to any source controller ports from
the host during migration.
NOTE:
The iSR6200 supports a maximum of four VPGs. To expose more than 255
LUNs from any Fibre Channel storage array, you may enable additional
VPGs in the iSR6200 blades. To present up to 1,024 LUNs (4
× 256) from the
same array to the iSR6200, repeat the preceding steps for each VPG.
NOTE:
LUN mapping is required only for online data migration for Fibre Channel
initiators (iSCSI initiators are not supported). LUN mapping is not
required for
offline data migration.
For HP-UX initiators, set the host type to HP-UX in the iSR6200. For all
other initiators, leave the host type set to Windows , the default.
