A
Configuring Gateway Ports as Initiators
Why you need to
check the port
settings
The factory might configure some gateway HBAs as target ports. However, most
gateways do not have targets. Therefore, before you start setup, you need to
ensure that the gateway HBAs that you are using to access both storage array
LUNs and disks are configured as initiators.
On N5200, N5300, N5500, N5600 gateways, for example, typical gateway
installations use 0a and 0c as a port pair or 0b and 0d as a port pair, for
redundancy. The factory might not have set the initiator port pairs in this manner.
Changing target
ports to initiator
ports
Complete the following steps to ensure that gateway HBAs are configured as
initiators.
Step Action
1 Power on the
gateway
and interrupt the boot process by pressing
Ctrl-C when you see the following message on the console:
Starting Press CTRL-C for special boot menu
2 Specify
Maintenance Mode
from the boot menu.
Do not proceed any further with gateway installation and setup at this
time.
3 Enter the following command to see which ports are configured as
target ports:
fcadmin config
4 For each target port that you want to change to an initiator port, enter
the following command:
fcadmin config -t initiator port#
