Guys,
We are having some problems with VTL machines, and the support guys
would like to find out if TSM rewrites the data headers when moving
from tape-to-tape.
If you mean tape labels: I don't do VTL, but it has been standard in
TSM that it requires removable media to have been previously labeled
with a static, unique identity. When it moves data across volumes,
the volumes retain their original identities, as is essential in
tracking volumes. I've not encountered anything in my reading which
indicates that VTL would be treated differently.
VTLs can provide replication, where the entirety of the volume,
including label, is imaged, but that's outside TSM.
