Configuring a Read/Write Optical Drive

There are two methods for configuring a read/write optical drive.


The read/write optical drive must be connected to the system and powered on.

Method 1

Method one is the faster of the two methods. It only configures the read/write optical drive specified. To use this method, you must provide the following information:

Subclass Defines how the drive is attached.
Type Specifies the type of read/write optical drive.
Parent Name Specifies the system attachment the drive is connected to.
Where Connected Specifies the logical address of the drive.

Enter the following command to configure the read/write optical drive:

mkdev -c rwoptical -s Subclass -t Type -p ParentName -w WhereConnected

The following is an example of a read/write optical drive that has a SCSI ID of 6, a logical unit number of zero, and is connected to the third (scsi3) SCSI bus:

mkdev -c rwoptical -s scsi -t osomd -p scsi3 -w 6,0 -a pv=yes

Method 2

Method two uses the Configuration Manager, searching the current configuration, detecting any new devices, and automatically configuring the devices. This method is used when little information is known about the read/write optical drive.

  1. Use the configuration manager to configure all newly detected devices on the system (including the read/write optical drive):
  2. Enter the following command to list the names, location codes, and types of all currently configured read/write optical drives:
    lsdev -C -c rwoptical
  3. Determine the name of the newly configured read/write optical drive using the location code that matches the location of the drive being added.
