Set the SCSI ID or Arbitrated Loop Physical Address
See instructions in the sections that follow to set a SCSI ID for a SCSI drive or an
Arbitrated Loop Physical Address for a Fibre Channel drive.
Setting the SCSI ID (SCSI Drive Only)
You can set the SCSI ID in one of three ways:
v
By placing jumpers on the SCSI ID connector
v By using a SCSI ID switch that is connected to the SCSI ID connector
v
By issuing a command from the library to set the SCSI ID through the drive’s
LDI interface
Setting the SCSI ID with Jumpers
The SCSI ID can be set on the drive by installing 2 mm jumpers on the drive’s
SCSI ID connector (see
2
in Figure 4 on page 3). Your drive may come set to a
default SCSI configuration, with jumpers already installed. To change the default
SCSI configuration, contact your sales or technical support representative. You can
change the SCSI ID by rearranging, adding, or removing jumpers.
To set the SCSI ID:
__ 1. Locate the SCSI ID connector (see
2
in Figure 4 on page 3).
__ 2.
Before attaching the SCSI bus cable to the server, determine the SCSI ID.
Make sure that the ID is not being used by another device.
__ 3. Referring to Figure 7, find the ID number that you chose then place jumpers
on the connector pins as shown (use a pair of needle-nose pliers to connect
the jumpers to the pins that are shaded).
Note: If you set the SCSI ID to 15, the drive will not necessarily be set to
that ID; instead, the drive will expect to receive the SCSI ID through a
command over its LDI interface.
Setting the SCSI ID with a SCSI ID Switch
If your enclosure uses a SCSI ID switch (rather than jumpers), connect the switch
to the drive’s SCSI ID connector (see
2
in Figure 4 on page 3). If any jumpers are
preinstalled, be sure to remove them before connecting the switch. The SCSI ID
