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.
If you are unable to connect to the
management GUI, consider the following
possibilities:
- You cannot connect if the system is not operational with at least one node online. If you know
the service address of a node, you can do one of the following:
- Use the service assistant to verify that the status of at least one node is active.
- And if the node is not active, use the LEDs to see whether any node status is
active.
If there is not a node with a status of active, resolve the reason why it is not in active
status. If the status of all nodes is candidate, then there is not a clustered system to connect to.
If the node status is service, see the topic that contains information about fixing node
errors.
- Ensure that you are using the correct system IP address. If you can access the service assistant
by using the service address or the technician port of a node, log in to find the node and system
addresses on the Access tab of the Node Detail table.
- Ensure that all nodes 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 whether the Ethernet network permits the connection. If the
ping fails, check the Ethernet network configuration to see whether 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 did not use 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:
- You can determine that the settings are incorrect if you can access the
service assistant on any node. Access the service assistant by using the technician port on the rear
of a node if it cannot be accessed over your network. Alternatively use the summary data that is
returned, when a USB flash drive is plugged into a node.
- 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.
- In the management GUI, use the options in
the to change the management IP settings.
- As an alternative to using the management GUI, you can use the chsystemip CLI command. Use ssh to the service IP of the
configuration node to correct the system IP address.
