N7000 Series System Active/Active Or High Availability Configurations; Configuring For Initiator Mode - IBM N7800 Hardware And Service Manual

Figure 4. N7000 series system rear ports
The Fibre Channel ports can operate in target or initiator mode. Fibre Channel
ports do not support mixed initiator/target mode. The default mode for the ports
is initiator mode. You do not need to configure the ports to use them in initiator
mode.
The Fibre Channel ports should be used in initiator mode to communicate with
tape backup devices, such as in a TapeSAN backup configuration.
Fibre Channel ports on HBAs cannot be configured in target mode. They can only
be used in initiator mode.
N7000 series system active/active or high availability
configurations
N7000 series system active/active or high availability configurations must be
cabled to switches that support public loop topology. To connect an N7000 series
system to a fabric topology that includes switches that only support point-to-point
topology, such as McDATA Director class switches, you must connect the
active/active or high availability configuration to an edge switch and use this
switch as a bridge to the fabric. For information about specific switch models
supported and fabric configuration guidelines, see the IBM System Storage N series
Fibre Channel and iSCSI Configuration Guide for your version of Data ONTAP on the
IBM N series support website, which is accessed and navigated as described in
"Websites" on page xx.

Configuring for initiator mode

About this task
To configure the N7000 series system back to initiator mode, complete the
following steps.
Procedure
1. Set the specified onboard ports to operate in initiator mode by entering the

following command:
fcadmin config -t initiator adapter
where adapter is the port number. You can specify more than one port.
Example: The following example sets onboard ports 0c and 0d to initiator
mode.
