Can you explain what exactly you mean by "legato console"? your message is 
rather confusing.

If your NetWorker Server is intact and you only lost your NMC server, then you 
should be able to backup and recover as usual and install the NMC on a 
different networker client.

You won't have the information about old jobs anymore if the gstdb is gone but 
you don't need it to do backups and restores. The important information is on 
the NetWworkere Server  ( on the online client file indices -- /nsr/index/*  
and media db /nsr/mm). 


If by "legato console" you mean the "Networker Server" (language!), then my 
suggestion is that you grab a copy of the Networker Disaster Recovery Guide 
from PowerLink.
( mmrecov, nsrck and mminfo/nsrinfo are your friends here).

If you have bootstrap backups (if not, well done and happy scanning!), you 
should  also have bootstrap reports with the location and ID's of those 
bootstraps (printed, emailed or on txt files). find the tape with the most 
recent good backup of the bootstrap,  configure a tape drive, load the tape  
and run mmrecov on that volume/bootsrap. That will bring your media db back 
online and restore your old resources database under a renamed "res.R" 
directory. 

You  should be able to do this in a matter of minutes once Nw server has been 
installed on the DR server. BTW use the same OS/platform and Nw version if 
you need to rebuild the server ( platform and NW version don't have to be 
strictly the same but this flexibility is limited to some platforms and 
versions).  


Once the bootstrap has been recovered you will need to stop NW, rename "res" 
to something different and "res.R" to "res". Then start Nw and continue with 
the DR procedure as documented on the DR guide.


Answers to your questions

1) 
If the NW server is intact:
 run "mminfo -avot". Then read the mminfo manual page (command reference guide 
in pdf or unix manual page "man mminfo" ) and the nsrinfo manual page (note: 
search for "namespace" on this one)   

if the server crashed do a DR and then a recovery of the indices. You will 
need mminfo and nsrck for that.


2) why do you thing you may erase the contents of the tapes? 


3) "everybody talks about this command line interface..."

 What exactly do they say about the command line interface and what is the 
problem with it? It is in your computer. Ask your administrator if you cannot 
find it. I can't provide any explanation  because you didn't provide any 
details.
