ATTO Technology Inc. FastStream VT 5300 Installation and Operation Manual
4.0 Modify storage
Use the FastStream GUI to replace a failed drive, add new drives or redesign VTL configurations.
The FastStream GUI takes you step by step
through many procedures which allow you to
modify your storage and VTL. Read all notes and
cautions carefully as you go to ensure the best
performance and use of your storage.
For every Virtual Tape Library created on the
FastStream VT 5300, an underlying RAID Group
is created from the selected drives to provide the
physical storage medium for the virtual tape
cartridges.
Initialize and verify drives
When you initially set up the FastStream, replace
a failed drive or add new drives to the FastStream,
perform drive initialization and verification to
ensure the integrity of these drives.
When the drives are selected, the ATTO
FastStream VT 5300 writes a pattern to the entire
drive; the drives may then be read back and
verified for integrity to fix soft errors and
reallocate bad blocks on your existing drives.
CAUTIONCAUTION
Selecting Drive Initialization causes all
previous storage data on the drive to be
erased. Make sure all of your information is
backed up before initializing drives.

Note
Do not restart the FastStream or disconnect or
power cycle drives during Drive Initialization
and Verification or you must start the
verification process from the beginning.
Add drives to a RAID Group
If you have unallocated drives, you can increase
the number of drives used by an existing VTL by
adding an unallocated drive to the VTL’s RAID
Group. The increased capacity of the RAID
Group will be seen as an additional Virtual Tape
cartridge in the library. You may have to add
more than one drive.
