Enabling Dynamic Reconguration
To enable dynamic reconguration, you must set two variables in the /etc/system le. You
must also set an additional variable to enable the removal of CPU/memory boards. Perform the
following steps:
1. Log in as superuser.
2. Edit the /etc/system le by adding the following lines:
set pln:pln_enable_detach_suspend=1
set soc:soc_enable_detach_suspend=1
3. To enable the removal of a CPU/memory board, add this line to the le:
set kernel_cage_enable=1
Setting this variable enables the memory unconguration operation.
4. Reboot the system to apply the changes.
Quiesce Test
You start the quiesce test with the following command:
# cfgadm -x quiesce-test sysctr10:slot number
On a large system, the quiesce test might run for up to a minute. During this time no messages
are displayed if cfgadm does not nd incompatible drivers.
Disabled Board List
Attempting to connect a board that is on the disabled board list might produce an error
message:
# cfgadm -c connect sysctrl0:slotnumber
cfgadm: Hardware specific failure: connect failed:
board is disabled: must override with [-f][-o enable-at-boot]
To override the disabled condition, two options are available:
