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".
Root Cause
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.
Solution
Upgrade
OS version to V300R005C00SPC100. You can get the guide from product
document.
Suggestions
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.
