External Storage XP user guide 57
Configuring external LUs
To use external storage devices connected to the local disk array, configure the connection to the external
LU. This involves setting port attributes on the local and/or external arrays, mapping external LUs, and
setting alternate paths.
This section describes procedures for using External Storage XP to configure external LUs.
