Editing a VTL Partition
Edit a VTL partition to modify the settings for the partition, for example, to change the emulated library model
or the number of storage slots and virtual tape drives.
To edit a VTL partition:
Quantum DXi6900 User's Guide
- Select the tape drive model emulated by the virtual drives in the partition. All
virtual tape drives in a partition must be the same model.
The following tape drive models are available:
Models
Quantum DLT-S4, SDLT600, SDLT320, or DLT7000
l
Certance LTO-2 and LTO-3
l
IBM LTO-1, LTO-2, LTO-3, LTO-4, or LTO-5
l
HP LTO-1, LTO-2, LTO-3, LTO-4, or LTO-5
l
Enter the number of virtual tape drives in the partition.
Note: If all tape drives are currently assigned to other partitions, you must
remove one or more tape drives from an existing partition to make them
available for use in a new partition.
Select the check box to enable data deduplication. Quantum recommends that
you enable data deduplication to optimize disk usage.
Note: Data deduplication is enabled by default. You cannot enable or
disable data deduplication after the partition is added. If data duplication is
disabled, then data compression is also disabled.
Select the check box to enable Auto Export. When a tape is exported by the
backup application, it is placed in a virtual I/E slot. After this, one of the
following actions occurs:
If Auto Export is enabled, the media is removed from the virtual I/E slot.
l
If Auto Export is disabled, the media remains in the virtual I/E slot.
