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 CD-ROM drive and choose the
highest-priority unused address for yours. On Table 1 on page 4, record the address
you chose for your CD-ROM 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 CD-ROM 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 32X SCSI-2 CD-ROM Drive SCSI
address is factory-set at 5. Refer to “Determining Your SCSI Device Address” on page 4
if you need instructions for selecting another SCSI address.
