Technical data

To add an ES45 with dual Memory Channel adapters into an existing cluster
with Memory Channel adapters jumpered for 512 MB, follow this procedure:
1. Shut down all cluster member systems except one.
____________________ Notes ____________________
Do not shut down a cluster member that has an application
with restricted placement policy unless the member that will
not be shut down is on the hosting list for the application.
See the
Cluster Highly Available Applications manual for
more information.
Modify the quorum votes as necessary to support a one-node
cluster. The Cluster Administration manual describes
how quorum is calculated and how cluster membership is
maintained.
2. On each cluster member that has been shut down, power off the system
and move Memory Channel jumper J3 to pins 1 and 2 to select 128
MB. See the chapter about setting up a Memory Channel cluster
interconnect in Cluster Hardware Configuration for more information.
3. Power up, but do not boot, each cluster member that has had the
Memory Channel jumper modified.
4. Shut down the last cluster member system.
5. Boot one of the cluster members that has had its Memory Channel
adapter re-jumpered for 128 MB.
____________________ Note _____________________
Readjust quorum votes and reset the placement policies as
needed to maintain a one member cluster with the booted
system.
6. Repeat step 2 for the last cluster member system.
7. Power on the last cluster member system and boot the remaining
original cluster member systems.
8. Use the clu_add_member utility to add the ES45 system to the cluster.

system to the cluster before changing the Memory Channel
