page 53; otherwise, go to “Procedure: Getting node canister and system
information using a USB flash drive” on page 53 and obtain the state of each of
the node canisters from the data that is returned. If there is not a node canister
with a state of active, resolve the reason why it is not in active state. If the state
of all node canisters is candidate, then there is not a clustered system to connect
to. If all nodes are in a service state, go to “Procedure: Fixing node errors” on
page 61.
v
Ensure that you are using the correct system IP address. If you know the service
address of a node canister, go to “Procedure: Getting node canister and system
information using the service assistant” on page 53; otherwise, go to “Procedure:
Getting node canister and system information using a USB flash drive” on page
53 and obtain the management IP address from the data that is returned.
v
Ensure that all node canisters have an Ethernet cable that is connected to port 1
and that the port is working. To understand the port status, go to “Procedure:
Finding the status of the Ethernet connections” on page 59.
v
Ping the management address to see if the Ethernet network permits the
connection. If the ping fails, check the Ethernet network configuration to see if
there is a routing or a firewall issue. Ensure that the Ethernet network
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
This topic assists you when you can see the management GUI login screen but
cannot log on.
Log on using your user name and password. Follow the suggested actions when
you encounter a specific situation:
v
If you are not logging on as
superuser
, contact your system administrator who
can 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 51.
