Power
Management
There are two possibilites of power management:
❑ system power management and
❑ device power management
System power management (Suspend/Resume):
This feature of the power management software of Solaris allows you to
power cycle the whole machine without losing the state of your current
activities. You can do this on SPARC machines by pressing the key in the
upper right corner of your keyboard.
This driver can handle the appropriate system calls so you are able to use
Suspend/Resume if you need to. This may be useful on a workstation but
not on a server machine.
Note
Network connections will not be interrupted until the timeout value
for the chosen protocol of the remote machine has expired.
Device power management:
This feature allows the system to power cycle individual pieces of
hardware that support device power management. If the hardware is
idle for a specified time it will be power cycled by the system. You can
configure the value allowed for the idle time in the file /etc/power.conf.
If you want to enable device power management for Allied Telesyn
adapters you have to edit power.conf.
For each adapter that is to be configured for power management,
proceed as follows:
Enter the following line (for each adapter):
device_name threshold
Each line must contain both entries in this order.
