If you are unable to connect to the management GUI from your web browser and received a Page not found or similar error, this information might help you resolve the issue.
If you are unable to connect to the management GUI from your web browser and received a Certificate expired or similar error, see Resolving a problem with SSL certificates.
If you are unable
to connect to the management GUI from your web browser and received a cipher error, SSL error, TLS error, or handshake error or similar error,
see Resolving a problem with SSL/TLS clients.
Consider
the following possibilities if you are unable to connect to the
management GUI:
- You cannot connect if the system
is not operational with at least one node online. If you know the service address of a node canister, either use the
service assistant to verify that the state of at least one node canister
is active, or if the node canister is not active, use the LEDs to
see if any node canister state is active. 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 the node state is service, see the topic that contains
information about fixing node errors.
- Ensure that you are using the correct system
IP address. If you know the service address of
a node canister, use the service assistant to gather information about
the node canister and the clustered system. You can also use the USB flash drive to obtain the system IP address from the data that is returned.
- Ensure that
all node canisters have an Ethernet cable that is connected to port
1 and that the port is working. Use the Ethernet
LEDs to understand the port status.
- 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.
- If the system IP address settings
are incorrect for your environment, take these steps:
- 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.
- 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.
- Use the options in the panel to change the management
IP settings.
- 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.
