Chapter 1 Configuring DR 7
For example, if you enabled the kernel cage, the following message is generated:
To Enable the Kernel Cage
A caged kernel confines the nonpageable memory to a minimal (most often one)
number of systems boards. By default the kernel cage is disabled, preventing DR
detach operations. If you plan to perform DR detach operations, you must enable the
kernel cage by using the system(4) variable kernel_cage_enable, as explained in
the following procedure.
Be aware that DR attach or addboard operations are enabled by default, regardless
of the setting of the kernel_cage_enable variable.
Note Before the release of version 7 of the Solaris software, the dr-max-mem
variable was used to enable DR. The dr-max-mem variable is not used to enable DR
in version 7 and subsequent versions of the Solaris software.
1. Using a text editor, edit the /etc/system file for the domain so that
kernel_cage_enable equals 1.
2. After all DR configuration tasks are complete, be sure to reboot the domain so that
this configuration can take effect.
3. Verify this configuration change in the /var/adm/messages file.
The following example is a section from a messages file, which indicates that the
kernel cage was enabled:
To Set Permanent Driver Parameters for
Network Drivers
If you use the ndd(1M) command to set the driver configuration parameters for
network devices, those parameters may not persist after a DR operation.
NOTICE: DR Kernel Cage is Enabled
set kernel_cage_enable=1
