Setting The Scsi Address - LG GSA-4167B Installation And Using Manual

Table 1. Data Access Priorities for SCSI Addresses (continued)
Priority
Lowest Priority
To find an available SCSI address on an AIX system, do the following:
1. At a system prompt, type:
lsdev -Cs scsi
Press Enter. Information similar to the following displays:
hdisk1 Available 00-01-00-1,0 1.0 GB SCSI Disk Drive
This information is interpreted as follows:
Column 1: device name (hdisk1)
Column 2: device status (Available)
Column 3: SCSI information (00-01-00-1,0)
Column 4: device type (1.0 GB SCSI Disk Drive)
In this example, the SCSI address for the device name ( hdisk1 ) is 1 as shown in
the 1,0 portion of the string in column 3. The 0 in the 1,0 portion of the string is the
SCSI bus number for that device.
2. Find an available SCSI address for the DVD-RAM drive and choose the
highest-priority unused address for yours. On Table 1, record the address you chose
for your DVD-RAM drive, as well as the names and addresses of any other installed
SCSI devices. Save this information for future reference.

Setting the SCSI Address

After you choose an available SCSI address for your DVD-RAM drive, you can install
the jumpers on the drive to match the selected address. The SCSI address can be set
from 0 to 6. Address 7 is reserved for the adapter. The 4.7GB SCSI-2 DVD-RAM Drive
SCSI address is factory-set at 4. Refer to "Determining Your SCSI Device Address" on
page 4 if you need instructions for selecting another SCSI address.
To set a SCSI address, you install jumpers onto pin positions 2, 3, and/or 4, located on
the jumper block, to set each position to On or Off . (See Table 2 on page 6 below.) To
set a position to On, insert a jumper onto both the top and bottom pins. To set a
position to Off, insert the jumper onto the top pin only.
Note: Jumpers are also installed in other positions on the jumper block to enable or
Refer to the figure on page 7 and to Table 2 on page 6 below as you go through the
following steps to set the SCSI address on this drive:
