You have something strange going on with your hosts file, srvbackup is listed several times
192.168.10.153 srvbackup_nfs srvbackup
192.168.69.9 srvbackup_bck srvbackup
Has that always been like that? Doesnt look right to me... im wondering if its causing a name mismatch with whats on the certificate.
Can you also post your /etc/nsswitch.conf file?
nbatd is not running because NBAC is not configured, or it has been turned off (USE_VXSS = PROHIBITED)
Did you have NBAC running or just logging in with root?
And also, you've got reverse lookup mismatches for the extra IP addresses configured. I'd resolve that.
I have NBAC not configured and USE_VXSS = PROHIBITED, yet nbatd is running. I dont know enough about it to say if thats normal though.
The reason why I thought it might be a concern is this error in the initial post:
Connecting to NBATD at [ srvbackup!1556!nbatd ] for establishing trust.
vrts.shared.server.CertificateAuthenticationException: NetBackup could not initiate a trust relationship with host "srvbackup". Ensure that your Domain Name Service (DNS) resolves the hostname to the correct IP address and check network connectivity.
the solution was
cp -rp /usr/openv/var/vxss/credentials/ /usr/openv/var/vxss/credentials.old
rm -rf srvbackup
rm -rf localhost6.localdomain6
./netbackup start -f -v
run again the jave program
