I have been implementing EMC Networker at work, and I needed to pull tape volumes out of the library for offsite use. The documentation, page 224 of the Administrator Guide for 8.0, has a bunch of procedures, but they are listed through the gui. I looked up nsrmm and nsrjb to see what is required to export a volume.
To unload a volume from tape:
To mark a volume as offsite:
nsrmm -o offsite
To withdraw a volume to the Cartridge Access Port (CAP):
Then you can go to the library and export the volume and pull it out.
To import a volume, load it into the CAP, then type:
to deposit a tape from the CAP back into the library. You may need to inventory it afterwards using scanner:
There are other options available, such as specifying devices or slots. You can look at the man pages for nsrjb, nsrmm, and scanner for more details.
Another helpful command is nsrjb by itself. It will show a list of all the slots in the library and what volumes are in them. It doesn’t do a full inventory, just a list of what the networker thinks is in the library. If the information gets out of sync, you may have to re-initialize the library using the -H option, or maybe just rescan the inventory with the -I option.
