Issue Description

During the system power-off, the FCC VM is manually shut down (misoperation). After the system is powered on, the FCC VM is not started (the VM startup status is the same as that before the host is restarted or powered off). As a result, the FC portal cannot be logged in to, and the FCC VM cannot be started.

Solution

Disable SSO and log in to the FC portal and start the FCC VM. After the portal is logged in to and the FCC VM is started, restore the SSO configuration. The procedure is as follows:

1. Disable SSO.

a. Use PuTTY to log in to the active VRM node.

Use the management IP address to log in as the gandalf user.

b. Run the following command and enter the password of the root user to switch to the root user:

su - root

c. Run the following command to disable SSO for the active VRM node:

python /opt/galax/vrm/tomcat/script/omsconfig/bin/sm/changesso/changesso.py -m ge

The operation is successful if the following information is displayed.

Shutting down portal.portal service is stopping.

d. Repeat steps a to c to disable SSO for the standby VRM.

The operation is successful if the following information is displayed.

Shutting down portal.portal service does not exist. Exit.

2. Use the VRM floating IP address to log in to the FusionCompute portal. Choose VM and Template > VM > Open the VM to start the active and standby FCC VMs.

3. Check whether the VM is started properly. Five minutes later, log in to the FCC portal. If the login still fails, contact Huawei technical support. If the login is successful, go to the next step.

4. Configure SSO.

a. Use PuTTY to log in to the active VRM node.

Use the management IP address to log in as the gandalf user.

The default password of the gandalf user is Huawei@CLOUD8.

b. Run the following command and enter the password of the root user to switch to the root user:

su - root

c. Run the following command to disable system logout on timeout:

TMOUT=0

d. Run the following command to configure SSO:

python /opt/galax/vrm/tomcat/script/omsconfig/bin/sm/changesso/changesso.py -m sso -v IP address of the VRM node -g Floating IP address of the FusionCube Center node

The IP address of the VRM node is described as follows:

In active/standby mode: floating IP address of the VRM node
In single-node mode: the management IP address of the VRM node
The configuration is successful if "completed!" is displayed.

e. Check whether the VRM node is deployed in active/standby mode.

If so, go to step f.
If not, no further operation is required.

f. Configure SSO on the standby VRM node.

Follow step a to step d to perform the configuration.
