Sun Microsystems Sun Blade 1000 Service Manual page 108

Note – There is a driver timing dependency between the CD-ROM or DVD-ROM
drive and the graphics board (frame buffer) used in the workstation. The driver for
the CD-ROM or DVD-ROM will not power on the drive during a workstation panic
unless an interrupt enabled is encountered or unless the system drivers are
operating in a polled mode.
Action
If necessary, perform the following procedure to disable power management for
the CD- or DVD-ROM drive:
1. Become superuser by typing su and the root password.
2. At the # prompt, type:
cat >> /etc/power.con
device-thresholds /pci@8, 700000/scsi@6/sd@6,0 always-on
^D
In the command line, ^D indicates that you should hold the Control key down
and type the letter D.
3. At the # prompt, type: pmconfig
4. Exit superuser.
