Continue running jobs even when tapes are changed (requires a copy pro-
file)
– This option lets you offload a specific set of virtual tapes to any physical
tapes that you load in specific slots in the stacker. The jobs will continue to run
even when you open the stacker door and change the physical tapes. To stop off-
loading, suspend the jobs.
The miSAN-V-Series remembers the details of the last offload to the physical
tape. If your backup software appends to the virtual tape after an offload, the next
offload will also append to the physical tape rather than doing a full copy. If the off-
load status is “PT is same as VT”, then the miSAN-V-Series will refuse to offload
until your backup software writes to the virtual tape again. You can force the
miSAN-V-Series to perform the full offload again by using the “Forget current con-
tents” option from the “Physical tapes” tab (See
“Physical Tapes Tab” on
page 97
). You may find this useful for doing testing.

Load tape onto disk...
Use this option to import the data from your physical tapes into the miSAN-V-
Series’s disk cache. This is useful for making multiple copies of a physical tape
cartridge by first staging the physical tape to virtual tape and then selecting to
“Offload disk to tapes” using multiple physical tapes.
Note, you can also do this by selecting the “Setup offload...” option, and then the
“Copy PT -> VT” option for the “Action”, which is the preferred way if you intend to
append to the backup and offload the appended data back to the physical tape. If
you want to import the data for restoring from the disk cache, then “Load tapes
onto disk...” is easier.
To import the data from the physical tapes, you will need one virtual tape for each
physical tape being imported that has enough capacity to hold the tape’s data
after decompression. Make sure the virtual tapes are safe to overwrite and not
mounted in any virtual drive. Then, select “Load tape onto disk...” to create the
jobs that will do the copying.

window with a list box, on the left, showing all the slots and physical tapes in the
Caution
Before selecting to copy from physical tape, make sure the virtual tape
has enough capacity to hold all the decompressed data to be transferred
from the tape cartridge. If the virtual tape is not large enough, the data
copied from the tape cartridge will be cut short. In that case, the
miSAN-V- Series will copy until the virtual tape is full and then stop.
Do not try to access a virtual tape while it is being copied to/from a
physical tape (e.g., by mounting it in a virtual tape drive or copying it to a
different physical tape), else the virtual tape could become corrupted
