Log in as root to the domain where you are adding the system board. Enable the
controller by entering:
#
vxdmpadm enable ctlr=
ctlr#
8.
When you have successfully attached and enabled the system I/O board, unfreeze
any frozen service groups:
#
hagrp -unfreeze
ser_grp_name
Repeat for each service group.

Verify that VCS is still up and running.
Detaching CPU/Memory Boards
Note
Use the following procedure if no I/O devices on the system board are used.
Make sure the
kernel_cage_enable
variable is set.
1.
Freeze the VCS service groups running on the domain where you intend to detach a
CPU/Memory board. Freezing the service groups prevents them from being taken
offline or failed over. Repeat the following command for each service group:
#
hagrp -freeze
ser_grp_name
2.
Connect to the SSP server and log in to the domain whose system board requires
Dynamic Reconfiguration (DR).
ssp:D1%
echo $SUNW_HOSTNAME
3.
Enter the
dr
(1M) shell:
ssp:D1%
dr
4.
In the window where you are running DR, start detaching the I/O board by entering:
dr>
drain
sb#
5.
Monitor the progress of the drain operation by entering:
dr>
drshow
sb#
drain
6.
When you see the message
Percent Complete= 100% (0 KBytes remaining)
complete the detach operation:
dr>
complete_detach
sb#
