Therefore, the explicit device path for the prompt shown on the previous page would be as follows:
Failed to build a path to the device for you.
Please enter the explicit device path:

Mappings
Storage Network Controllers (SNCs) can usually be configured for multiple mapping schemes of the SCSI
bus: target: LUN address to the FC LUN addresses. The HBA can then have its own mapping of FC LUNS
to target: LUN combinations. Some routers and Fibre Channel HBAs also support non-permanent mappings
that can dynamically change as devices are added or removed from the buses.
Note
To avoid the problems of a dynamically changing bus address, configure the
ADIC FC router to use indexed addressing, which permanently maps the bus:
target: LUN to the FC:LUN.
