want check whetehr "cluster serial number" unique across all clusters?
Solved! See The Solution
The cluster serial number should be unique across the each cluster, and each node has it's own serial #
If you are talking about cluster UUID, yes its uniq
The fact you can search using it, in autosupport to find your cluster, makes me believe its globally uniq.
::> cluster identity show Cluster UUID: 1cd8a442-86d1-11e0-ae1c-123478563412 Cluster Name: cluster1 Cluster Serial Number: 1-80-123456 Cluster Location: Sunnyvale Cluster Contact: firstname.lastname@example.org
I don't think the "Cluster Serial Number" is Uniq
The cluster UUID is universally unique, as per the standard definition of "UUID", and the cluster serial number SHOULD be unique - but it isn't. We only hand them out to a single customer, but it isn't node-locked and can be used in multiple clusters.
The cluster serial is set based on the cluster base license key entered. It sometimes happens with conversions, rushed installs etc, that the cluster base license key is unavailable, and a well known temporary key is used which corresponds to serial 180000099, so you will sometimes see customers with multiple clusters with the serial 180000099. The cluster serial number can be changed if necessary.
Hope this helps!
We have develeoped a system and were using "Cluster Serial Number" to identify the cluster. Later we realised that it is not uniqe across clusters. COuld you please share the steps to change the "Cluster Serial Number"?
Was the process to change the number documented?
I have 2 new clusters and the clusters have the same serial number ..
As per my other comment - the process to change it is to add the license code for the other cluster base ID and the serial number of the cluster will change.
Hope this helps!
