configuration is compatible with the gateway and subnet or prefix settings.
Ensure that you have not used the Ethernet address of another device as the
management address. If necessary, modify your network settings to establish a
connection.
v If the system IP address settings are incorrect for your environment, take these
steps:
1. Determine the service address of the configuration node canister. You can
determine this if you can access the service assistant on any node canister,
alternatively use the summary data returned, when a USB flash drive is
plugged into a node canister.
2. You can temporarily run the management GUI on the service address of the
configuration node. Point your browser to service address/gui. For example, if
the service address of the configuration node is 11.22.33.44, point your
browser to 11.22.33.44/gui.
3. Use the options in the Settings > Network panel to change the management
IP settings.
4. As an alternative to using the management GUI, you can use the chsystemip
CLI command to correct the system IP address settings by using ssh to the
service IP of the configuration node.
Problem: Unable to log on to the management GUI
If you can see the management GUI login screen but cannot log on, you have
several options for correcting the problem.
Log on using your user name and password. Complete the suggested actions when
you encounter a specific situation.
v If you are not logging on as superuser, contact your system administrator to
verify your user name and reset your account password.
v If the user name that you are using is authenticated through a remote
authentication server, verify that the server is available. If the authentication
server is unavailable, you can log on as user name superuser. This user is
always authenticated locally.
v If you do not know the password for superuser, go to “Procedure: Resetting
superuser password” on page 250.
