Configuring Tape Drive Parameters
You can configure Fibre Channel tape drive loop ID, topology, and speed
using the operator panel or the Web client. On the Web client, you can
also view the actual topology and speed, plus the tape drive’s world-
wide node name (WWNN) and other information about the tape drives.
You cannot configure SAS tape drive settings. A SAS tape drive’s SAS
address is automatically and uniquely generated based on a unique
World Wide Name (WWN) that the drive receives when it is configured.
You can view SAS tape drive settings (but not change them) on the Web
client.
Note: If the affected partition is online, it will be taken offline before
the parameters are set, and brought back online after they are
set.

Drive Configurable Settings
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.
