Hello Managers,
We are in the process of configuring Oracle RAC Cluster Guard on a pair
of Compaq DS20srunning Tru*64 5.1 PK 4 with a single memory channel.
We wish to configure the cluster guard with node 1 as primary and node 2
as secondary on a two node cluster.
The Mc0 (memory channel) seems to get changed when we configure the
cluster guard, renderiing the network services unaccessible.
Any light you can shed on this will be much appreciated.
Thanks in advance,
Aru Arunasalam

The configuration parameters are as below: the network addresses are
modified slightly since the servers belong to a customer.
