Hey Sean,
Sorry to hear, you seem to be in some strife ...
Ok to set a few things straight ..
Lgto_gst.db is the database for the management console, basically stores
performance & reporting data for networker, it doesn't store the indexes /
media database or the networker config
Assuming you are on a windows server
Indexes c:\program files\EMC networker\nsr\index
Media Database c:\program files\EMC networker\nsr\mm
Networker Config c:\program files\EMC networker\nsr\res
If you re-label a tape, then as far as networker is concerned the data is gone
from the tape, you could probably get a third party specialise company to
recover the data, but it's not something you'd probably able to do with the
tools generally available to standard admin people
I would strongly suggest that you contact EMC support to get them to assist you
with the recovery process
Failing that, you'll need to get the hardware working correctly. The tape
drives / library visible to the OS - you should be able to see each of the tape
drives in device manager, and their respective device paths, the command
"inquire" may assist here (is the tape library connected to the backup server
or via a storage node?).
Once you have a working tape library in networker, you should be able to go
through the disaster recovery guide to recover your environment (I assume that
you have a valid and recent bootstrap report?)
Hope that this helps a bit ...
Mat

Subject: [Networker] Manually restoring lgto_gst.db on Windows 2008 R2 - NW
8.0.1
Good afternoon, all.
I have a box that was updated in-place from Networker 7.6.2 to 8.0.1.
Everything went smoothly for about a week until a system reboot (after some
patches).
After the reboot, the media index was empty and no tapes had labels. Long
story short, after a junior analyst uninstalled and re-installed the app rather
than just re-discovering the library, our media index and networker configs are
zero'd out.
I have the original lgto_gst.db files and can copy them into the new c:\Program
Files\EMC Networker\Management\ folder but when the services are started, the
config is still zero'd out.
I've tried mmrecov to no avail. Because Networker will not mount the tape in
one of the drives, I cannot run scanner. Despite the Emulex control panel
stating that the drives are \\.\Tape0 through 3, it says that there is no such
device.
I've tried manually moving the tape into the drive using the library's tools
and can see the tape in the drive. It simply will not mount. Very strange.
Any ideas? I'd hate to lose a year's worth of backups.
Like I say, I have a pre-existing lgto_gst.db that was created during the
install of 8.0.1 but it doesn't seem to work.
For info, the library is an HP EML-245e.
As an aside, if a tape gets re-labeled, is the data on it lost forever? I was
*thinking* about labeling a tape and mounting it in networker but don't want to
lose any data.
Cheers,
--Sean
