Don't worry, the data is still there.  Just update the valid volumes to
read/write status if they're physically in the Library after you run an
audit.

the order I would take care of this is:
1.  make sure no clients or processes are running (other than Admin
Sessions).
2.  Make sure no volumes are mounted.
3.  Run "Audit libr" with the checklabel=barcode option (can't remember
the exact syntax for some reason run: help audit library)
4.  Check any errors or "can't find tape in slot" whatever messsages.
5.  Update any volumes still showing as "Unavailable".

Or you could update them ahead of time, but you will want to check and
make sure they are physically in the library.

run:
update vol <volsernum> access=readwrite

This should turn them back to writable, and everything should go back to
normal.

Hopefully you're running offsite copies using DRM, so at the worst, you
will have to restore the volumes from the offsite copies.
