154 PowerVM Migration from Physical to Virtual Storage
In Figure 7-1, LPAR1 and the Virtual I/O Server can both access the LTO4 tape
drive since both have a dedicated adapter with SAN zoning in place. The
migration process removes the dedicated tape access from LPAR1 and
re-presents the tape drive using the virtual Fibre Channel capability of the VIOS.

Note: IBM PowerVM Virtualization Managing and Monitoring, SG24-7590,
details the requirements for SAN switches, AIX levels, and Virtual I/O Server
levels to support NPIV (virtual Fibre Channel). Ensure that these requirements
are met before attempting the migration.
In addition, the AIX file set devices.vdevice.IBM.vfc-client.rte
must be installed
on the client logical partition for the VFC function to work.
