Enabling and Disabling Save and Resume
Although the Save and Resume feature provides an extremely
convenient method of powering down and powering on again, it does
present two drawbacks.
•
It may compromise the security of the system, as described
above.
•
It requires the existence of the
save
partition on the boot disk
which is the same size as the system’s main memory. For
example, a SPARCbook with 128MB of main memory requires
a 128MB
save
partition. See “Boot Disk Partitions” on
If either of these issues poses a serious problem, the Save and Resume
facility can be disabled. Save and Resume can be disabled with a
reversible command, as described below, or can be disabled
permanently by assigning the
save
partition for general data storage.
ò
Disabling Save and Resume
To disable Save and Resume, enter the following command:
# saveresume -n
SAVE Partition was /dev/rdsk/c0t0d0s4
Note
This example shows the save partition for a SPARCbook 3000 model. For a
SPARCbook 3 the save partition is
/dev/rdsk/c0t3d0s4
. Make a note of
the correct partition to use if you intend to re-enable Save and Resume later. See
“Boot Disk Partitions” on page 6-5.
This command disables the Save commands (such as
Pause-O
) and
unmounts the save partition. To power the system down, you can use
the normal Solaris shutdown commands. For example:
# shutdown -i0
When the ok (OpenBoot) prompt is displayed, press
Pause-O
to power
off. Restart the system in the conventional way for a desktop Solaris
system.
