Legato Networker Label Issue
Hi,
We have a tape that was written using Legato Networker V6.1 containing information from a Tru64 UNIX system. It appears that during a tape re-label operation in the jukebox, this tape was accidently re-labeled with a bunch of tapes that we wanted to re-label. We have looked at the Legato documentation, and they state a tape is essentially re-initialised when a label operation is run on a tape, and therefore the data on that tape is no longer readable. Does anyone know if this is the case, or if there are any work-arounds to this, where we will be able to gain access to the savesets that are on the tape? We know that the index + saveset information for the tape has now been wiped out of the Networker "database", and so if we could somehow re-introduce the information back in, and gain access to the data, it would be a lifesaver. Anyone have any idea if this can be done? Many thanks. Tony |

You haven't mentioned what sort of tape you're using, but generally the issue here isn't with Networker, it's with the tape hardware. When you label a tape you write to the start of the tape, and then drive will then follow the label with an "end of data" marker. Even though your existing data will still be there after the end of data marker (other than the area over-written with the label obviously) there is no way to get past this marker with a standard drive. There are companies who will be able to recover the remaining data - at a generally significant cost - but even then it will depend on the layout of the savesets on the tape as to whether you will be able to recover the data back into Networker using scanner. Scott. |
