LTO5 drive and LTO4 tapes

Hi, Wanted to know the steps to configure Networker 8.2.4.9, so that a HP Ultirum LTO5 drive running on a HP MSL G3 Series library, could write data off the Data Domain, to an LTO4 tape media.

Recently, I upgraded the drive from a LTO4 drive to an LTO5 drive, with an assurance from HP that, the new drive would be able to read LTO4 tape media (which I took literally) and never bothered to order LTO5 tape media. I still checked over a dozen forum, and the HP support with all kinds of assurances that there should not be an issue.

So, long story short, I tried to run the inventory command from within networker and it checked every tape in the library (24 tapes Library) and basically put back in the cradle saying “Media type mismatch”.

I am being told, that there is some setting which needs to be configured on Networker, and I am very new to the Networker backup application. Any help from any one…would be much appreciated.

Re: Recycling media…not as expected

Good day to all,

First off, we are using Networker 8.1.3.10.

We would like to recycle and re-use tapes that have gotten filled up over time and I’m not getting the results one would expect when using the “Manual Recycle” option when I perform a “label” action on a tape. I have read some threads on this topic already and all seem to use the same method to “recycle/re-use” media, but perhaps I’m not following the proper procedure to accomplish this.

My understanding is I should be able to “Manually recycle” tapes by right clicking a device with the appropriate media mounted, select “label…” and then add a checkmark in the “Manual Recycle” option.

This action is successful in that, the media shows as empty when verifying it on the “Media tab”, however I thought that I would be able to use the entire space on the tape again, since my understanding is networker will simply overwrite all the data on that tape with new information (there is no physical formatting of the media). But it seems our tapes get filled using a fraction of the total amount of space on the media. For example, if I use an LTO4 tape, I would expect to be able to now write up to 1.5TB of data anew but this is not the case for us.

Here is an example of what I mean:

The tape was “recycled” and showed 0% but filled with only 9Gigs of data.

Linux LTO-4/5/6 Hardware AES Drive Encryption

For a number of reasons I have been trying to find a way to encrypt my backup tapes. I’m currently running Bacula for my backups and it’s support for Drive based encryption is I have to call a script or something to set the key in the drive.

How can I set the encryption options on the tape drive in Debian Linux?
