All VMs had stopped, and cannot ping to Fusion Sphere IP but all blades still can login normal. Any method to start VM again or not

Hello, friend!

Before the VM fails to start, check whether any operations have been performed on the hypervisor or whether any exceptions have occurred.

Wait for your feedback!

Hello, friend!

You can try the following commend:

# nova list --all-t | grep "SHUTOFF" | cut -d" " -f2 | xargs -t -L1 nova start

The nova list --all-t | grep "ACTIVE" | cut -d" " -f2 | xargs -t -L1 nova stop command is a high-risk operation. You are advised to contact the TAC for preventive maintenance. Prevent service faults.

Hope this helps!

Now we can login all blades

Hello, friend!

1. Log in to the FusionSphere OpenStack controller node.

Use PuTTY to log in to a controller node in the FusionSphere OpenStack system using the IP address corresponding to the Cascading-Reverse-Proxy field.

The default username is fsp.

2. Switch to the root user.

su - root

3. Run the following command to disable user logout upon system timeout:

TMOUT=0

4. Import environment variables. For details, see Importing Environment Variables.

5. Run # nova list --all-t | grep "SHUTOFF" | cut -d" " -f2 | xargs -t -L1 nova start.
