159 BackBox H4.00 User Manual
Data Store ID: Specifies in which Data Store the virtual volumes will be
created. This value applies to new virtual volumes created in this group. It
cannot be modified to change the location of volumes previously created.
Primary Volume Group ID: Specify the corresponding Volume Group ID in the
primary site, when its ID is different. This parameter is applicable only for
SECONDARY Data Stores.
Tape Catalog: Specify the volume catalog type (None, DSM/TC, TMF, QTOS or
CA).
Auto Scratch at Load time: Indicates if the content of an expired virtual
volume can be deleted at load time. The expiry test depends on the tape catalog
type and its integration in BackPak. Note that for QTOS and CA catalogs, there is
no expiry test when auto-scratch is enabled: any tape volume requested for
output is assumed to be expired. Refer to the “Auto-Scratch Mechanism” in the
product description chapter.
Delete Expired Volumes: Indicates if a volume that has become SCRATCH in
DSM/TC, TMF or QTOS must be deleted in storage. This controls the functionality
of the macro BB017_FREE_EXPIRED.
Media Type: Specifies the media type that will be registered in the
TAPEVOLUME entry of DSM/TC when the volumes are created. This must match
the device type returned by the command MEDIACOM INFO TAPEDRIVE $virtual-
tape-drive. To solve a mount request, BackPak will search for a media
compatible tape device.
The default media type provided by the VTC tape emulation is LTO3.
For old Guardian tape systems not supporting LTO3, it is possible to change this
default for the legacy 3480 cartridges in the internal VTC configuration; the
Volume Groups must then be configured with CART3480 media type.
LTO4 media type is available to support the VLE tape encryption.
LTO2 media type is also available to support old tape catalog versions (CA tape
catalogue). LTO2 media must be operated on LTO3 tape drives.
Warning threshold (Min % of Scratch volumes): Specifies a threshold that
is evaluated in the daily batch OBB017. When the number of SCRATCH volumes
of the Volume Group is less than the specified percentage, the message #3313
is issued in EMS: For example, “Only 17% of SCRATCH volumes are available in
Volume Group <name>” can be issued when the threshold is configured to 20%.
This setting applies only when Tape Catalog is set to DSM/TC or TMF.
Migration to BackBox: Tells the state of a possible migration from a legacy
storage product to the BackBox product. This parameter is available to Volume
Groups attached to a PRIMARY Data store only.
Possible values:
None Possible migration phases are completed. Volume virtualization is still
available, but without the migration specific Auto-import automation.
