But when i installed the NBU client in the client server, i straight away installed the NBU 6.5.4 client package instead of first installing the NBU 6.5 client package. Pls.advise what are the other options to be checked in both master server and client m/c. ( both Redhat ENT 5.2 )
Best Practices. You need to install 6.5 client first then apply 6.5.4 update. I thought your method would have produced an error of sorts based on pre-requisites?
HOW TO: How to perform a manual NetBackup client removal on Linux
Remove and install 6.5 GA client version first
All release updates are CUMULATIVE - that is, they contain ALL fixes in previous versions. For example, NetBackup 6.5.4 contains all fixes from 6.5.1 to 18.104.22.168 inclusive.
Check your firewall setting also.
