split brain

Hi,

In a situation when i encounter a split brain what should i do first is to shutdown the minicluster with the lower number of nodes or a node (if there are 2 node vcs) and then inform the manager or first inform the manager?

w_online shows me that i have a split brain.

 

tnx

    Have you had a look at them?

    Other useful documentation is VCS Admin Guide.
    Look for these topics:

    About data protection 
    (Continue to read about I/O fencing)

    About cluster membership and data protection without I/O fencing 

    Split brain should be prevented at all cost.
    Above information and Related articles on the right will tell you how.

    By the time you 'notice' a split brain situation, it is probably too late to take action.
    Except contacting the Backup admin to restore corrupt data....
