Path status

There is a problem with connection
to the external array. The following
are possible causes:

Cannot detect port

The fibre cable is not connected
properly.

The topology setting between
the external and target ports
does not match.

If the external array is
connected through switches, the
switches' settings might not be
appropriate.

Check if the fibre cable is
connected properly, and use LUN
Manager to set the Fibre Channel
port properly.

LUN Manager may have set LUN
security.
Check if LUN security is enabled.
If LUN security is enabled, disable
LUN security.

Connecting XP512/XP48 Disk Arrays

When connecting an XP512/XP48 Disk Array as the external array, you must set the port's host mode
to PC Server (0C).

Also, the port attribute must be the target or RCU target port.
