You can see that there are 2 Spectra Python tape libraries, each containing 4 IBM LTO4 tape drives.

Note

EMC Networker will not recognize the second tape library. There seems to be a problem that the second tape library has the same SCSI controller number as the first one.

configuration

The MHVTL configuration files are located in /etc/mhvtl. You may stop MHVTL with /etc/init.d/mhvtl stop, change the files as desired and start MHVTL with /etc/init.d/mhvtl start once again.

nwsrv:/etc/mhvtl # ls
device.conf  library_contents.10  library_contents.30  mhvtl.conf

The virtual tapes are located as files in directory /opt/vtl.

nwsrv:/opt/vtl # ls

MHVTL forum

There’s a forum for MHVTL, run by nia, where you can ask questions, have a look at other configurations and so on…
