Restrictions on Initiator/External MIX Mode The restrictions on the Initiator/External MIX mode are as follows:
• The restrictions on the High Speed mode are also restrictions on the
Initiator/External MIX mode. For the restrictions on the High Speed mode,
see the LUN Manager User’s Guide.
• The point-to-point connection is not available.
• You cannot set the Initiator/External MIX mode on the external ports of the
Standard mode that have already been used to map the external volumes.
You cannot set the Standard mode on the port of the Initiator/External MIX
mode that has already been used to map the remote command device. You
need to delete the mapping of the external volume and then change the
setting of the port mode.
• Using a port of the Initiator/External MIX mode, the command device of
the external storage system can only be recognized by the discovery
operation and mapped. Other volumes can be neither recognized by the
discovery operation nor mapped using the port of the Initiator/External MIX
mode.
