Chapter 3: UNIX Disaster Recovery

Please insert the volume on which save set id 20076 started into /dev/rmt/0hbn.

Once you have loaded the appropriate volume, the following message appears:

Scanning /dev/rmt/0hbn for save set 20076; this might take

a while...

NetWorker then scans the volume for the appropriate save set and recovers it. The NetWorker media database and resource database are recovered when the following message appears:

If your resource files were lost, they are now recovered in the ‘res.R’ directory. Copy or move them to the ‘res’ directory, after you have shut down the service. Then restart the service.

Otherwise, just restart the service.

If the on-line index for the server-name was lost, it

 

can be recovered using the nsrck command.

 

Task 5: Rename the NetWorker Server Configuration Files

Because the configuration files cannot be reliably overwritten while the NetWorker software is running, mmrecov recovered the res directory as res.R by default. In addition, mmrecov might have recovered another server’s configuration file in this directory.

To rename the configuration files:

1.

Stop the daemons by entering the nsr_shutdown command at the

 

command line:

 

nsr_shutdown -a

2.

Rename the existing /nsr/res directory to /nsr/res.orig:

 

mv res res.orig

3.

Rename the recovered /nsr/res.R directory to /nsr/res:

 

mv res.R res

4.

Restart the NetWorker server by first entering the nsrexecd command,

 

then entering the nsrd command, for example:

 

nsrexecd

 

nsrd
