Configuring Optical Disk Drives

To display the disk device files that are configured on your system, use the sgscan

command with the disk parameter:

# /usr/openv/volmgr/bin/sgscan disk

/dev/sg/c0t0l0: (/dev/rdsk/c0t0d0): "IBM DCAS32160SUN2.1G"

/dev/sg/c0t1l0: (/dev/rdsk/c0t1d0): "HP C1113F"

/dev/sg/c0t2l0: (/dev/rdsk/c0t2d0): "HP C1113F"

/dev/sg/c0t5l0: (/dev/rdsk/c0t5d0): "HP C1160F"

/dev/sg/c1t0l0: (/dev/rdsk/c1t0d0): "SONY SMO-F541"

/dev/sg/c1t1l0: (/dev/rdsk/c1t1d0): "SONY SMO-F541"

/dev/sg/c1t2l0: (/dev/rdsk/c1t2d0): "SEAGATE ST11200N SUN1.05"

Note All device types can be displayed using the all parameter when executing

sgscan. This command can be helpful for associating disk devices with other SCSI

devices that may be configured on the same adapter. Usage: sgscan

[all|basic|changer|disk|tape] [conf] [-v]

Optical disk device files are located in the /dev directory and have the following formats.

Volu me h ead er d evice:

/dev/rdsk/c

ADAPTER

TARGET

d0s0

Character device:

/dev/rdsk/c

ADAPTER

TARGET

d0s6

Where:

◆ ADAPTER is the logical adapter number as shown in the sgscan output.

◆ TARGET is the SCSI ID.

Examples of Optical Disk Device Files

Example 1

Using the previous sample sgscan output, if the desired optical disk drive connects to

SCSI ID 5 of adapter card 0, you would use the following device paths:

/dev/rdsk/c0t5d0s0

Character device:

/dev/rdsk/c0t5d0s6
