Curious to know what issues/what type of clusters you had trouble with?  What method were you using?  We generally use http and have updated clients in a application cluster without any issues.


All clusters, if they're configured as per most best practices, can fail to detect a running instance of NetBackup.  If you have a physical server backup and a virtual server backup on the same physical server, neither know about each other.  You could rip out the binaries in the middle of a running job.

This is the same issue on all active/passive clusters whether they're Windows or Unix.  The only one that's immune is VMS because you don't need virtual servers.

Similarly, when you're dealing with virtual servers, you can't control how many instances of NetBackup are running on the same physical system.  You can't even count how many client licenses you need from a master server since it can't tell how many unique physical servers there are.
