       Re-Initializing tapes on cdfsga
       -------------------------------



First, remember that the current tapes cost $5.12 each.  

This number could be used in thinking about how much
time to spend on re-initializing tapes.


----------------------------------------------------
Then, one sets up the current ocs version:
----------------------------------------------------
   > setup ocs

----------------------------------------------------
Allocate a drive, and ask the operators to mount the tape 
with writing enabled.
----------------------------------------------------
   > ocs_allocate -d exabyte_8500
   cdfsga cdf11
   > ocs_request -t cdf11 -v RK6142 -w
   ocs_request: Success

----------------------------------------------------
Determine the device file for this drive
----------------------------------------------------
   > ocs_devfile -t cdf11
   /dev/rmt/tps6d2nrnsv.8500

----------------------------------------------------
Relabel  the tape.  WARNING, this is equivalent
to deleting all the files on the tape.  BE SURE you want
to to this.
----------------------------------------------------
   > setup mt_tools
   > mtlabel -crw -f /dev/rmt/tps6d2nrnsv.8500 RK6142

----------------------------------------------------
Please be sure to rewind and unload the tape
----------------------------------------------------
   > mt -t /dev/rmt/tps6d2nrnsv.8500 rewind
   > mt -t /dev/rmt/tps6d2nrnsv.8500 unload

----------------------------------------------------
Please remember to deallocate the drive
----------------------------------------------------
   > ocs_deallocate -t cdf11
   ocs_deallocate: Deallocated any:cdf11
----------------------------------------------------


NOTE: The ocs_request command can take sometime, since the operator at FCC
has to physically mount the tape in the drive.
