Setting up a Recovery Package on the
Recovery Cluster
Use the procedures in this section to configure a recovery package on the
recovery 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 writable. Since it cannot be guaranteed
that either half of a paired volume is always writable, they may not be
used as a cluster lock disk. Using a disk as 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 recovery
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 recovery cluster:
# mkdir /etc/cmcluster/<package_name>
