If you have a large number of clients you need to gather the Netbackup and OS version details you can automate the process by using two NBU commands-

bppllist and check_coverage

Use the bppllist command to generate a text file that will list all of the clients from the Netbackup policies.

Then use the check_coverage -hardware command to generate a hardware report for the clients created from the bppllist command.

bppllist can be found-

On Windows:  

<install path>Program Files\VERITAS\netbackup\bin\admincmd

On Unix:

<install path>\netbackup\bin\admincmd

check_coverage can be found-

On Unix:

/usr/openv/netbackup/bin/goodies/check_coverage

On Windows:

\install_path\Veritas\NetBackup\bin\goodies\check_coverage.bat

First using the command - bpplclients -allunique -noheader > c:\Temp\hosts.out

This generates a client host list that then can run the following command against the hosts.out file create from the first command-

Windows-
<install path>\Program Files\VERITAS\netbackup\bin\goodies\:check_coverage -hardware -hosts c:\Temp\hosts.out

UNIX-
<install path>/netbackup/bin/goodies/,/check_coverage -hardware -hosts /tmp/hosts.out

This would generate the text file that would contain the NBU and OS version of the clients listed in the host.out file.

e.g
# ./check_coverage -hardware -hosts /tmp/hosts.out
Generating Hosts Report
Completed report for hosts

The Hardware/OS Report can be found in /tmp/hardware_rpt.04-12@13:56

#cat /tmp/hardware_rpt.04-12@13:56
