Virtual TapeServer 6.03.42 Installation Guide

24 | Cabling and Connecting VTS
Also, note that you do not have to use all of the SCSI buses (nor converter ports) for
VTDs. You can use the ports as initiators for legacy SCSI tape drives.
Here is an illustration of the slots on the back of the base model VT5900-E (DL385 G2). If the
P800 card is installed, it is placed in slot 3 (below slot 4).
Here is an illustration of the HVD and LVD ports on the back of the SCSI converter:
Note If you replace one or both of the SCSI cards with the 2Gb FC card(s), as described in
SCSI-to-Fibre Channel Adapter Upgrade on page 121, and you set any of the FC ports
to target mode (to connect the port to a virtual device), bus numbering will change.
After you replace the SCSI card(s) and reboot VTS, refer to the Manage system limits
page in the VTS web interface to see how the buses were renumbered. Contact your
VTS service and support representative for help correlating bus numbers to ports on
the back of the VTS server.
Connecting the VT5900-G
The VT5900-G is built on a 2U (3.5 inch) chassis and provides up to four Fibre Channel buses,
numbered 0-3. A dual-channel 4Gb FC card is also provided for connection to external storage
(buses 4 and 5). This base model allows the use of four 2Gb FC buses for connecting virtual
tape drives (no ports on the 4Gb FC card can be used for virtual connections).
Here is an illustration of the slots on the back of the base model VT5900-G (DL385 G2). If the
P800 card is installed, it is placed in slot 3 (below slot 4).
