Hello, friend!

Have a nice day!

1. Use PuTTY to log in to any VRM node.

Ensure that the management IP address and username gandalf are used to establish the connection.

2. Run the following command and enter the password of the root user as prompted to switch to the root user:

su - root

3. Run the following command to view the status of the active and standby VRM nodes:

service had query

Information similar to the following is displayed:

service had query

Determine whether the RESS values in the command output are all normal.

4. Use PuTTY to log in to the node whose PHASE value displayed in 3 is Activated.

Ensure that the management IP address and username gandalf are used to establish the connection.

5. Run the following command and enter the password of the root user as prompted to switch to the root user:

su - root

6. Run the following command to perform active/standby switchover:

sh /opt/galax/gms/common/ha/switchOverHA.sh

7. Determine whether the active/standby switchover is successful by performing the following steps:

a. Run the following command to check whether the ROLE status of the original standby VRM node has changed from standby to active and whether the ROLE status of the original active VRM node has changed from active to standby:

service had query

b. Ensure that the RESS values in the command output are all normal.

c. Check whether a floating IP address can be used to log in to FusionCompute.

Hope this helps!
