Configuring Optical Disk Drives

The following example output shows that a disk drive, a tape drive, an optical

drive, and SCSI robotic control are configured:

◆ hdisk0 is a disk drive at controller 1 (00) and SCSI ID 0 (0,0)

◆ rmt0 is a tape drive at controller 1 (00) and SCSI ID 3 (3,0)

◆ omd0 is an optical drive at controller 1 (00) and SCSI ID 6 (6,0)

◆ ovpass0 refers to the SCSI robotic control for controller 1 (00) and SCSI ID 2

(2,0)

hdisk0 Available 00-00-0S-0,0 2.2 GB SCSI Disk Drive

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

omd0 Defined 00-00-0S-6,0 Other SCSI Read/Write Optical

Drive

ovpass0 Available 00-00-0S-2,0 VERITAS Media Changer

b. Create the device files for the optical drive by using the following command:

mkdev -c media_changer -s scsi -t ovpass -p

controller

-w

lun

Where:

controller is the logical identifier of the drive’s SCSI adapter, such as scsi0 or scsi1.

id is the SCSI ID of the optical drive (not the robotic connection).

lun is the logical unit number of the optical drive.

For example:

mkdev -c media_changer -s scsi -t ovpass -p scsi 0 -w 6,0

Use the following command to obtain the logical identifier for the optical drive

you just created:

/usr/sbin/lsdev -C -s scsi

c. Verify the temporary ovpass device file created in step b.

/usr/openv/volmgr/bin/scsi_command -d /dev/

ovpass_id

-inquiry

Where ovpass_id is the logical identifier assigned to the temporary device. For

example if the temporary ovpass device was ovpass2, enter the following:

/usr/openv/volmgr/bin/scsi_command -d /dev/ovpass2 -inquiry

The output shows the following:

removable device type c_8h_HP
