Modifying Virtual Tape Drives
You may need to modify one or more virtual tape drives, particularly those that were
preconfigured on VTS. You may need to rename virtual tape drives according to your chosen
naming convention. This section describes how to modify virtual tape drive properties.
Note If you delete the virtual tape drive, you must restart the TapeServer service.
When adding or modifying a virtual tape drive in VTS, you must define its properties. The
following table describes the properties and specifies whether each property is presented to
the host server host when the virtual tape responds to a host’s query:
Property Description
Presented
to Host?
Bus ID The ID of the bus on the VTS server to which the host is
connected. This ID is not presented directly to the host; the
host will see this bus numbered according to its numbering
scheme. If the connection is over Fibre Channel, the bus ID
is associated with a port WWN that is used by the host to
identify the VTS server. If the connection is over SCSI, the
bus ID on the VTS server has no special significance to the
host.
Indirectly
Target ID With SCSI, this is the SCSI ID on which the virtual tape
drive responds. This ID is not presented to the host if the
connection is over Fibre Channel. To avoid confusion, this
ID should be set to 0.
Yes, for
SCSI only
Logical unit
number (LUN)
The sub-ID on the bus. This ID is used by the host for SCSI
and Fibre Channel connections.
Yes
Initiator ID The SCSI ID of the host. This ID has no significance if the
bus is in target mode and, in this case, this ID should be set
to 7.
Yes
Name A user-friendly name for the virtual tape drive. Yes
Media type The type of tape drive that the virtual tape drive emulates. Yes
Host type The type of host (NonStop S-series, NonStop Integrity,
NonStop BladeSystem, or UNIX server).
No
Serial number The serial number or other string describing the virtual
tape drive. Only alphanumeric characters should be used.
Yes
