Guys,
Issue :
Netbackup server sends alert NDMP communication failure once everyday. But there is no issue to run scheduled backup jobs.
Environment : Netbackup server is RHEL 6.2 which also works as Media server, Netbackup 7.1 is running on it. NDMP host is Netapp filer 2240. Backup is being taken on HP MSL 4049 tape.
Troubleshooting steps followed :
Everyday I receive a NDMP communication error alert messages once. I don't know why. I tried to troubleshoot but no luck. Even Symantec doesn't have any answer apart from what they have in their KB. They said, pw authentication might have wrong but for our setup it is correct. This is already verified multiple times. Enabled all logging even. Network communication is also fine. Following error I could see in bptm log file :
avrd[15164]: ndmp_public_session_create() failed: Unexpected NDMP message - not a connected message
tldd[24890]: TLD(0) ndmp_public_session_create_wCred failed with error code -1005
I don't see any suspicious messages on filer.
Solution : I don't still find out. Please share if you anyone knows.
FYI: I observed that tape drives periodically go off line. Hence, I had to up them. I have deployed a work around script which all check if drive is down or not. It'll up if it is down.
Check on netbackup server : tpconfig -l or vmoprcmd -d
up it : vmoprcmd
