NDMP restore: Error bpbrm (pid=5768) could not open event Global\NetBackup BPBRM Media Ready Event 8284, The system cannot find the file specified.

Hello,

Any help or hint to troubleshoot will be greatly appreciated. I have the error while NDMP NAS restore.

I have the following setup:

  • NDMP NAS configured on a AIX 7.1 master server Netbackup 7.6.1.2
  • NDMP NAS is HNAS 3100(Hitachi)
  • NDMP backup/restore use the remote NDMP infrastructure.
  • Media server that performed the NDMP backup is on Windows 2008.

The situation I am experiencing is as follows:

  • Backup works fine without error
  • Restore works fine without error when restoration is done to alternate location on the NDMP NAS
  • Restore to original location end with status 0 with all files restored, however I have an error logged in the job details(in bold below):

    My primary concernt will be about the restored data? does it resored correctly and data looks good?

    could you attached the restore log located in master server /usr/openv/netbackup/logs/user_ops/<userid>/logs

    The next log to check will be bpbrm on the media server. You will probably need to increase logging level to 3 or higher. You may also want to log a Support call with Veritas. They will need level 5 logs of bpbrm (and probably a bunch of other logs as well) including ndmpagent. PS: I have tried to Google the error 'Media Ready Event 8732' but cannot find anything. I think you should log a Support call with Veritas.

    Hello RamNagalla,

    The restored data looks good, but that error pops up everytime a restore to original location is performed. I have attached the log if that could tell you anything(jbp-29544457979919999800000000024-VExaay.txt).

    Strangely the error does not appear in the user_ops log you requested but is present in the activity monitor job details as follows:

    bpbrm exit with staus 0 , and  then (in my guess) it is trying to post some event on Windows and not able to find it

    I have found some lines in the bptm logs that indicate that the error may be related to multiplexing:

    I googled around your error:

    2016-03-11 15:16:45 - Error bpbrm (pid=5768) could not open event Global\NetBackup BPBRM Normal Exit Event 8284, The system cannot find the file specified.

    and found that the event ID could be random, but mostly the solution points to permission issue during restore. Try to check in your system logs (of the Hitachi filer) and see if there is anything stand out.

    Also check the successfully-restored files to see if their permissions are all right (or different from the original) .

    Thank you watsons,

    No event in the NAS except the following:

    Information    NAS   2016-03-15    13:55:57 (UTC-0400) NDMP(440): Starting operation for client MEDIA_YYY, standard NDMP user. 
    The permissions are all right I did a test with a testfile as below.

NAS[EVS1]:$ ls -l
-r-xr-xr-x    -  1        0        0        0 2016-03-11 14:35:17-04:00 testfile
NAS[EVS1]:$ rm testfile
NAS[EVS1]:$ ls -l

Restore to original location from Netbackup

NAS[EVS1]:$ ls -l
-r-xr-xr-x    -  1        0        0        0 2016-03-11 14:35:17-04:00 testfile

    I wonder why the error occurs only when restore to original location is performed and not when I restore to al alternate location on the same filesystem on the same NAS.
