Problem: Unable To Log On To The Management Gui; Problem: Cannot Create A Clustered Storage System - IBM Storwize V7000 Unified Problem Determination Manual

of both node canisters is candidate, then there is not a clustered system to
connect to. If the node state is service, go to "Procedure: Fixing node errors" on
page 220.
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 212; otherwise, go to
"Procedure: Getting node canister and system information using a USB flash
drive" on page 213 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 218.
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 211.
