❖
gateway
is
the
IP
address
of
the
subnet
router
❖
[a|b]
specifies the controller whose network parameters you are configuring
For example:
# set network-parameters ip 192.168.0.10 netmask 255.255.255.0
gateway 192.168.0.1 controller a
# set network-parameters ip 192.168.0.11 netmask 255.255.255.0
gateway 192.168.0.1 controller b
8.
Enter the following command to verify the new IP addresses:
show network-parameters
Network parameters, including the IP address, subnet mask, and gateway address are
displayed for each controller.
9.
Use the
ping
command to verify connectivity to the gateway address. For example:
# ping 192.168.0.1
Info: Pinging 192.168.0.1 with 4 packets.
Success: Command completed successfully. - The remote computer
responded with 4 packets.(2011-12-19 10:20:37)
10.
In the host computer’s command window, enter the following command to verify
connectivity for both controllers:
ping controller
controller_A_IP_address
ping controller
controller_B_IP_address
If you cannot access your system for at least three minutes after changing the IP
address, you might need to restart the Management Controller(s) using the serial CLI.
When you restart a Management Controller, communication with it is temporarily lost
until it successfully restarts.
Enter the following command to restart the Management Controller in both
controllers:
restart mc both
11.
When you are done using the CLUI, exit the emulator.
12.
Retain the IP addresses (recorded in step 1) for accessing and managing the
controllers using either RAIDar or the CLUI.
Using HyperTerminal with the CLI on a Microsoft Windows host
On a host computer connected to a controller module’s mini-USB CLI port, incorrect
command syntax in a HyperTerminal session can cause the CLUI to hang. To avoid this
problem, use correct syntax, use a different terminal emulator, or connect to the CLUI using
telnet rather than the mini-USB cable.
Be sure to close the HyperTerminal session before shutting down the controller or restarting
its Management Controller. Otherwise, the host’s CPU cycles may rise unacceptably.
If communication with the CLUI is disrupted when using an out-of-band cable connection,
communication can sometimes be restored by disconnecting and reattaching the mini-USB
CLI cable as described in step
2
and
