Yes, clearly it wants the tape media (4). That is the last Full backup, and
the Incremental (5) was done relative to it.
You haven't given enough information to really analyse what is going on, but I
can guess. For example, I don't know what Volumes were used at each stage.
On your Incremental (5) it looks like you have specified the input storage to
be Disk when it is in fact tape.
If you want to do multiple Virtual Backups, I don't think it is going to work
by mixing media. This probably should be documented but is not. I believe
that it will work much better if you keep everything on the same Media Type.
Or you will need to run subsequent Virtual Full specifying Tape as the input
device.
Possibly there is a problem with doing multiple Virtual Full backups. One of
the conditions for successful Virtual backups is that the input Pool and
output Pool (read and write) must be different. We have a test case in the
regression scripts called virtual-backup2-test, which does multiple Virtual
Full backups. It accomplishes it by moving the Volume the Full was written
on to a different Pool. This permits keeping the input and output pools
different.
