the parameters are set, and brought back online after they are
set.
Setting Description
Loop ID 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 is assigned a
default loop ID of 61. The tape drive installed in the
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.
Requested The requested topology connection mode can be set
Topology* 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)
Requested The requested interface speed can be set to Auto
Speed* (Auto-negotiate — default), 1 Gb/s, 2 Gb/s, 4 Gb/s, or
8 Gb/s, depending on the tape drive. For example, 
LTO-4 drives will not support speeds faster than 
4 GB/s, and LTO-6 or higher tape drives will not
support speeds less than 2 Gb/s. .
* Auto tries to use the most appropriate/fastest drive settings. On the Web
client, the Setup - Drive Settings screen displays both the requested and the
actual FC topology connection mode and interface speed. If FC drives are not
connected to the host, the negotiated actual settings appear on the screen as
"unknown."
