Configuring DR

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.
