Typically, within a domain, system boards have their functions duplicated on other system boards. For example, a board with CPU or memory can be removed dynamically because another board has the equivalent functions.
- Page 5 Dynamic Reconfiguration in VCS Environment Detaching and Attaching I/O System Boards In the configuration shown below, VCS runs on Domains A and B with service groups online on Domain A. Shared storage consists of a VxVM disk group with Dynamic Multipathing (DMP) enabled.
- Page 6 Dynamic Reconfiguration in VCS Environment Detaching I/O System Boards with DMP Enabled Make sure the kernel_cage_enable variable is set. 1. Freeze the VCS service groups running on the domain where you intend to perform DR operations. Freezing the service groups prevents them from being taken offline or failed over.

To verify that the board is no longer configured, type the following command: dr> drshow The detached board should not appear in the detailed listing. 11. Exit the dr shell: dr> exit 12. If the board is not to be immediately replaced, unfreeze any frozen service groups: # hagrp -unfreeze ser_grp_name Repeat for each service group.

When you have successfully attached the CPU/Memory board, unfreeze any frozen service groups: # hagrp -unfreeze ser_grp_name Repeat for each service group. 8. Verify that VCS is still up and running. Using VM without DMP Enabled If you have the Volume Manager DMP feature disabled for some or all of the disks in the shared storage, and you must perform DR operations within the cluster, we recommend using the VCS DiskReservation agent to guard against data corruption.
