onbar error on openserver 5.05

Posted in 2003

Summary

User on SCO OpenServer 5.0.5 with IDS 7.31UC7 and ISM 2.2 got NetWorker "RPC error, Unable to send" / "Send Chunk to MMD failed, Bad file number" when running onbar -b against ~10GB of data, with bar_act.log showing the process killed by signal 13 (SIGPIPE). Respondents questioned the command syntax (-l vs -L 0), asked for bar_act.log details and storage-manager configuration, and suggested isolating the fault by backing up a small database to an ISM disk directory instead of tape. The poster reported small backups and restores work fine; no resolution for the large backup is recorded.

Hi, I guess you somehow have to decide what you want to do : onbar -b -l # use this command to backup logical log files or onbar -b -L 0 # use this command to do a level zero archive but to me "onbar -b -l 0" seems a bit ambiguous. You didn't say which version you're using (version of IDS and ON-Bar - try "onbar -V" to find out), and you probably should check the ON-Bar activity log file for error messages from ON-Bar. E.g. try (possibly as user informix) something like : awk '$1 ~ /BAR_ACT_LOG/ {print $2}' ${INFORMIXDIR}/etc/${ONCONFIG} | xargs tail -20 Regards, Martin -- Martin Fuerderer IBM Informix Development Munich Data Management Solutions "WANG PING" <aiwngye@sohu.com> Sent by: forum.subscriber@iiug.org 06.08.2003 12:14 To: ids@iiug.org cc: Subject: onbar error on openserver 5.05 [1641] OS: sco openserver 5.05 The storage software: ism2.2 I excute onbar -b -l 0 error: NetWorker: RPC error, Unable to send NetWorker: Send Chunk to MMD failed, Bad file number

I have Informix DS 7.31UC7 on SCO open server 5.0.5,the tape device is DDS-4,the store manager software is ISM2.2.when I execute onbar -b to backup about 10GB data, I recieve the following messages in daemon.log log. nsrmmd #1: pid 6302 frag size 538976288, invalidating connection NetWorker: RPC error, Unable to send NetWorker: Send Chunk to MMD failed, Bad file number The following messages in bar_act.log log Process 1658 received signal 13. Process will exit after cleanup. Due to the previous error, logical restore will not be attempted. Thanks in advance for your help.!

Have you configured the storage manager? - devices, users etc. What does the onbar log (bar_act.log) say? Do you have any issues with any process or database in the Informix instance? Why do you use onbar and not ontape?

Hi It's not clear if you were doing a backup or restore since the beginning of the message mentioned executing "onbar -b" for backup, then the bar_act.log had 2 lines which indicate a restore. The signal 13 mentioned is some kind of pipe error SIGPIPE. So, I'm not sure what's happening. It may be worthwhile to configure onbar to interface with a local ism disk directory (disable the tape device, disable the NetWorker, and disable the actual storage manager). Clean up the bar_act.log and BAR_DEBUG_LOG (if enabled), and daemon.log, then create a small database and try running the backup (onbar -b) and see if those messages are still present. At this point, it could be some kind of environment setup problem, tape device problem, NetWorker problem, storage manager (Legato?) problem, or onbar problem. So, hopefully, this will help isolate the problem. thanks. Davis.
