42 Configuring Your Library
The paths to open the appropriate screens are as follows:
• From the web client, select Setup Wizard > I/E Station Slots .
• From the operator panel, select Setup Wizard > I/E Station Slots .
Setting Tape Drive Parameters
You can change the following parameters:
• The SCSI ID for a SCSI-attached tape drive
• The loop IDs, topology connection mode, and interface speed for a Fibre-attached tape drive
If the affected partition is online, it will be taken offline before the parameters are set, and brought back
online after they are set.
Each device on a SCSI bus, including the host bus adapter (HBA) needs to have a unique SCSI ID.
Changing the SCSI ID is necessary when there is a duplicate ID on a single bus. Typically, the HBA SCSI
ID is set to 7. For example, if two tape drives are connected together on the same bus, each tape drive must
have different SCSI IDs and they must be different from the HBA SCSI ID.
For SCSI tape drives, a SCSI ID can be set to a value between 0–15. The library assigns the following
default SCSI IDs to SCSI tape drives:
• 5U control module: 1 and 2
• 9U expansion module: 3, 4, 5, and 6
For FC tape drives:
• The loop ID can be set to a value between 0–125. 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
control module is assigned a default loop ID of 61. The tape drive installed in the 5U 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.
• 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
Note
This operation cannot be performed concurrently by multiple administrative
users logged in from different locations. You can access the screen, but you
cannot apply changes while another administrative user is performing the same
operation.
Note
If you configure zero I/E station slots, you will not be able to perform I/E Station
and drive management functions.
Note
The FC topology connection mode and interface speed can be set through the
web client only, not through the operator panel user interface.
