Setting up a Primary Package on the Primary
Cluster
Use the procedures in this section to configure a primary package on the
primary cluster. Consult the MC/ServiceGuard documentation for more
detailed instructions on setting up MC/ServiceGuard with packages, and
for instructions on how to start, halt, and move packages and their
services between nodes in a cluster.
NOTE Neither the primary cluster nor the recovery cluster may configure an
XP series paired volume, PVOL or SVOL, as a cluster lock disk. A
cluster lock disk must always be writeable. Since it cannot be
guaranteed that either half of a paired volume is always writeable,
neither half may be used as a cluster lock disk. A configuration with a
cluster lock disk that is part of a paired volume is not a supported
configuration.
1. Create and test a standard MC/ServiceGuard cluster using the
procedures described in the user’s manual, Managing
MC/ServiceGuard.
2. Install ContinentalClusters on all the cluster nodes in the primary
cluster (Skip this step if the software has been preinstalled)
NOTE MC/ServiceGuard should already be installed on all the cluster
nodes.
Run swinstall(1m) to install ContinentalClusters and MetroCluster
Continuous Access (CA) products from an SD depot. The toolkit
integration scripts, environment file and contributed scripts will
reside in the /opt/cmcluster/toolkit/SGCA and /usr/sbin
directories.
3. When swinstall(1m) has completed, create a directory as follows
for the new package in the primary cluster:
# mkdir /etc/cmcluster/<package_name>
