Chapter 5 Configuring Your Library
Setting Tape Drive Parameters
Dell PowerVault ML6000 User’s Guide 85
For SCSI tape drives, you can set the SCSI ID to a value from 0 to 15. The
library assigns the following default SCSI IDs to SCSI tape drives:
• 5U Library Control Module: 1 and 2
• Each 9U Library Expansion Module: 3, 4, 5, and 6
For FC tape drives:
• The loop ID can be set to a value from 0 to 125. A unique loop ID is
selected by default for all FC tape drives installed in the library. For
example, the tape drive installed in the top drive bay of a 5U Library
Control Module is assigned a default loop ID of 61. The tape drive
installed in the 5U Library Control Module’s bottom drive bay is
assigned a default loop ID of 63.
If you change the default loop IDs, make sure each FC tape drive with
a topology setting of Auto (LN), Loop (L), or Auto (NL) has a unique
loop ID.
You cannot change the Loop ID if the Topology is set to Point to
Point.
• The requested topology connection mode can be set to one of the
following:
• Auto (LN) — Auto-configure trying L-Port first
• Loop (L) — Force L-Port
• Point to Point — Force N-Port
• Auto (NL) — Auto-configure trying N-Port first (default)
Notes About Point to Point:
- You can use Point to Point if the tape drive is connected
via a switch.
- You cannot use Point to Pointif the tape drive is
connected to an FC I/O blade or connected directly to a
host.
