The problem has occurred If you are added your client ip address in master netbackup server while configure backup policy.
So change client hostname with domain name instead of ip address of client.

ORA-19511: Error received from media manager layer, error text:
   BEError(0x80004005) Unspecified error 
 

Cause :

The problem has occured because I have already configured symantec backup exec agent software on particular database server, So it has created own orasbt.dll file in c:\windows\system32 directory and that particular database sbt device is configured with symantec backup exec . While the existing system running,  I installed veritas netbackup client  agent also on the same server without removing symantec backup exec and removed orasbt.dll file.

If symantec backup exec is already install on the same server, and if we are trying to install netbackup then it does not overwrite on orasbt.dll file.

This is the reason when i take backup, the allocated channel showing symantec backup exec not veritas oracle netbackup.

Solution :

Uninstall Both client software (Symantec Backup exec and Vertias ntbackup)

delete orasbt.dll file from  ”C:\windows\system32\”

Install again Veritas Oracle netbackup.  Now Its works fine.
