Adding a VTL Partition
Add a VTL partition to present the storage capacity of the ETERNUS CS800 as a VTL
partition that is compatible with standard backup applications. You can add up to 64
partitions. When you add a partition, you must specify the type of physical library to emulate
and configure virtual tape drives and storage slots.
The number of virtual tape drives (VTDs) totaled across all configured partitions must not
exceed a maximum value. The maximum number of VTDs allowed varies depending on the
system configuration:
l
ETERNUS CS800 -
o
Entry - 80 VTD (pre-installed)
o
Scale - 256 VTD (pre-installed)
l
A virtual tape drive is considered active if a cartridge is loaded in the VTD. Make sure to
configure the backup application software so that the maximum number of active VTDs
is not exceeded at any time. Exceeding the maximum number of active VTDs may
cause backup jobs to time out.
l
If you plan to replicate partitions to another ETERNUS CS800, make sure that every
partition name and barcode number on each ETERNUS CS800 is unique. There cannot
be duplicate partition names or barcode numbers on the ETERNUS CS800 or on a
ETERNUS CS800 receiving a replicated partition.
CAUTION!
Make sure the backup application on the host is configured for the correct number of
tape drives and storage slots emulated by the VTL partition. If you do not, the backup
application might not operate correctly.
