There are two versions. One is for OceanStor OS and another is for cluster software.
1. From the first step of deployment, we can get the version of cluster software. And the onsite version is V300R005C00SPC100.
2. From feedback of customer, the OS version is V300R005C00B018. They are not matching/same.
You can login to a node to get the version of OS by the command "cat /etc/EulerLinux.conf".
When OceanStor 9000 nodes are sent to customer, there is no cluster software in the nodes and only Euler OS is installed.
If the OS version is old, and the version of cluster software is new, the deployment will fail.
When deploy the OceanStor 9000, please make sure that the two versions are same.
A RM will be created to check if the two versions are same. If they are not same, give the prompt that upgrade the version or else.
