Netbackup- Status Code 48: the DB backups suddenly failed

hi 

DO you have hosts file or DNS in place for the name resolutions?

if the if the resolution query too more time it may be possible for getting EC 48?

if you are using DNS its more likely possible.

please add the Client entires in etc/hosts file and check how it works

Thanks Marianne for the quick response

>Are DB clients running backups to disk followed by bpbackup to backup the disk backups to NBU?Or >Agent backups started by external scheduler on the clients?

To make it easier maybe I concentrate on the MS-SQL agent backup first ignore the oracle. Yes our backup started by external scheduler but on the master server

Checked, looks fine

> Maybe DNS and/or hosts files have changed?

Yes there is a possibility, because the policies that failed are not new , just out of sudden it failed, but I don't know what to checked.

>You will need logging to troubleshoot the problem.
>If user-initiated backups, bprd log on master server is first to check.

I will check on it

Hehe yes, that's why I am asking here, we are in the middle of upgrading.

 

Thanks Marrianne

bprd is not finding the host name... 

Please provide the output of below commands in master server

bpcltncmd -hn bccprj01-bck

bpclntcmd -Ip <IP of bccprj01-bck>

grep bccprj01 /etc/hosts

nslookup bccprj01-bck

 

Hi Nagalla,

 

 

please provide the log of bprd for the process 20182

if the verbose is not 5, please raise up the verbose to 5 and let the job fail then collect the logs of bprd.

and also, how many hosts entires you have in /etc/hosts file?

if it has more entiries, could you move this client entires to beginning of the /etc/hosts fine and check how it working

Hi All, Yesterday morning after midnight the problem resolved by itself , I didn't really fix it, I still don't know what wase the caused but here wassome facts: o The day the thing happened there aws a problem in one of our exchange server, I suspect it could be our secondary DNS server for Windows(The Windows DNS, the domain like company.local, our other DNS is in l Linux for serving company.com.sg), this Windows DNS manage by other department. o The problem only affecting the one that use SQL Agent and SAP agent. o During the problem I did nslookup or ping with the name from Master, Media and client to each other and were OK. o For the client the name resolving done on ..\etc\hosts (but I didn't check wheter it is also automatically registed on the Windows DNS) Anyway thank you very much for Marianne and Nagala for the supports. Regards, Iwan I will still monitor the situation if I found something I will post it to this forum

I found something else, it could be the caused, at the same day I also edit the /etc/hosts I accidently put a note without a remark (#) then at night I did restore back the /etc/hosts.

 

Regards,

 

Iwan
