d. On the Choose A Virtual Tape To Edit page, select the virtual tape drive to edit (the
one for which you deleted the connection) and click Edit. This page is then displayed:
e. From the bus drop-down list, select the bus ID to which the host server is connected.
To determine the bus ID, you must find the PCI slot number on the back of the VTS
server module where the SCSI or Fibre Channel cable connects from the card to the
target. Labels indicate the bus number for each port.
f. From the target drop-down list, select the ID on which the virtual tape drive will
respond. This is the ID that the host uses to identify its target, and the ID typically
ranges from 0–15.
g. From the lun drop-down list, select the logical unit number. This number identifies
the sub-ID on the bus, and this ID typically ranges from 0 – 255. The appropriate
LUN value depends on the host server.
h. From the initiator drop-down list, select the SCSI ID of the host bus to which VTS is
connected. Leave the default value for the initiator; typically, this is 7. This item is
not presented to the host.
i. In the name field, specify a name for the virtual tape. This name is for use in the
interface and by EMS. It is also noted in the configuration file. The name is case-
sensitive.
j. Select the media format from the tape_type drop-down list. This property defines the
type of tape that the virtual tape emulates. This property also specifies the icon
selected for the logical drive on web interface pages.
Note Do not select RAID, which is provided for Manufacturing’s purposes only.
k. Specify the host, or initiator, type by choosing an option from the host_type drop-
down list. This property is for reference only; it is not presented to the host. This
property also specifies the icon selected for the virtual tape on the interface pages.
l. In the serial_number field, specify the serial number of your virtual tape. You can
specify up to 10 alphanumeric characters. This string is presented to the host and
should be unique (across all VTS servers and VTDs in the environment). This field is
optional unless the host server is a NonStop BladeSystem. If you do not enter a serial
number, the BTLI will be presented to the host as the serial number but not shown in
the web interface. The default BTLI serial number is unique per VTS server but other
VTS servers may create the same BTLI serial number. In an environment with more
