Configuring Optical Disk Drives

If the device files for the SCSI optical disk drives exist, they show up in the output as

hdisk0, hdisk1, and so on.

hdisk0 Available 00-01-00-0,0 400 MB SCSI Disk Drive

hdisk1 Available 00-01-00-1,0 400 MB SCSI Disk Drive

rmt0 Available 00-01-00-3,0 Other SCSI Tape Drive

For hdisk0, you would use the following device path:

/dev/rhdisk0

3. If the device files for the desired optical drive’s SCSI ID do not exist, you can create

them with the following command:

mkdev -c disk -s scsi -t osdisk -p

controller

-w

lun

Where:

◆ controller is the logical identifier of the device’s SCSI adapter, such as scsi0 or

scsi1.

◆ id is the SCSI ID of the drive connection.

◆ lun is the logical unit number of the drive connection.

An example for an optical disk drive on controller 1 and SCSI ID 5 follows:

mkdev -c disk -t osdisk -s scsi -p scsi0 -w 5,0

4. You can display the newly-created logical identifier for the device by using the

following command:

/usr/sbin/lsdev -C -s scsi

hdisk0 Available 00-01-00-0,0 400 MB SCSI Disk Drive

hdisk1 Available 00-01-00-1,0 400 MB SCSI Disk Drive

rmt0 Available 00-01-00-3,0 Other SCSI Tape Drive

hdisk2 Available 00-01-00-5,0 Other SCSI Disk Drive

ovpass0 Available 00-01-6,0 VERITAS Media Changer

The device files for hdisk2 have been created and you can now use them.
