Linux license
 

Hello everybody,

Have you ever met term "Cluster Support License"?
How to check it at all?

BR,
Igor

Without details, it will be hard for anyone to provide a meaningful answer.

Unfortunately, I have no more details except "Cluster Support License for Redundant Version (one year)".
I'm afraid that cluster might stop working after expiring of one year period.

Linux version:

[root@]# uname -a
Linux imme01 2.6.18-194.26.1.el5 #1 SMP Fri Oct 29 14:21:16 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

OK, so this is a paid support license? For what cluster software (what is its name)?

This
specifically the 'el5' bit means you are running V5 of RedHat enterprise Linux. This requires a paid support subscription from RH to get updates and support.
To check the exact version, use
then phone RH with the hostname and version details unless you already know how to login to RHN (RedHat Network).
They'll ask if you have the subscription num or 'license' num from the orig install media box.
They should be able to id your RHN acct and tell you who is the official owner/contact.
