Kernel cage memory is a DR specific feature that minimizes the number of system boards on which kernel pages are allocated. This feature must be enabled to make DR operations effective since it is disabled by default in the Solaris 8 OS and Solaris 9 OS. Otherwise, any DR operation fails. This feature is enabled by default in the Solaris 10 OS.
Add the following line in /etc/system and reboot the system to enable this feature.
set kernel_cage_enable = 1
After the system reboots, the system administrator can verify if the DR feature has become available by reviewing the file /var/adm/messages which should show the message:
NOTICE: DR kernel Cage is ENABLED.
The DR command drcstat -system can also be used for verification. Please read section 3.2 "drcstat(1M)" for more details.
