[ee01akk]

Networker 7.3.4 server and Networker module for exchange 5.1.1.

Extra log files.

You have an exchange Cluster and did not provide the -a switch with nsrexchrc.

Please dont provide .raw files, convert them with nsr_render_log myRaw.raw >Textfile.txt

to somethin eays readible. Not everyone has the render_logs command at hand or the time for converting.
And please provide more information what you want to do and what the problem is. Otherwise its difficult to help.

Hi,

We are using Windows 2003 x64 SP2, our Exchange infrastructure is 2007 SP1 with Rollup 3.

We upgraded the Networker module to version 5.1.1 on the 31st October so the “The feature "NetWorker Module for Microsoft Exchange Server/11" is not properly enabled for client uos-cl-ex7-l1.soton.ac.uk” errors from March and June are not applicable as they refer to an older version of the module and we were having some licensing issues at the time.

The output of the nsrlic –v command is attached as are the event logs.

The database we are trying to restore is 240GB and the servers are using the same network switches that have worked for previous restores many times before.

Thanks for your help.

The errors I get are just like the following example from the attached file:

46842 1227615279 5 0 0 5812 8432 0 uos-msg00021-cp nsrxchrc 25 Not recovered: %s (%u.%u) 3 23 54 /Information Store/First Storage Group/E0000223E1E.log 5 10 1224962720 5 10 1224965177

The recovery finishes but as it can’t recover the log files it can’t replay them and so the recovered data is useless.

I've attached the log file in text format as a ZShare upload.

In your log file is following entry:

46845 1227606502 1 0 0 5812 8432 0 uos-msg00021-cp nsrxchrc 28 Preallocating "%s" Size: %s 2 23 44 W:\RS1\Recovery Storage Group\RSGMailbox.edb 0 12 240670120944
46833 1227613837 5 0 0 5812 8432 0 uos-msg00021-cp nsrxchrc 60 %s(%d): XBSA error 0x%0.4x returned while getting XBSA data. 3 23 6 rcutil 1 3 524 1 1 3

So you should taken a look into the xbsa.messages file on your exchange server.

xbsa errors are often network problems,
in your case it might be due to insufficient storage capacity !

Check your W:\ volume : is there enough capacity for your *.edb and the log files ?

 

[ee01akk]

The W:\ drive is a 10GB mount point with a 500GB LUN mounted to W:\RS1 for restoring a database and a 136GB LUN mounted to W:\RS1\Logs. The database we are trying to recover is 240-ish GB plus a maximum of 136GB of log files (as the Log LUN is that size) so we have plenty of spare space.

I think networker has a problem crossing the mountpoint borders.

Retry the restore with traditional LUNS :
Take your 500 GB Lun create mount it as volume eg. W:\
and recreate your RSG on W:\ the retary the restore.

If we were to fall back to the previous version of the Networker Module (5.1) as the backup I am trying to recover was backed up using v5.1.1 will the older module recover the data correctly?

Also, is there a command that can check to see if the backup on the Networker server contains the log files my recovery is trying to restore?
