Parameter discovery and default parameters

By way of automatic package parameter discovery by the Site Controller Easy Deployment script, most of the package attributes are automatically populated in the Site Controller and managed packages’ configuration files. The rest are set to recommended default values. The following table explains more about how each Site Controller package parameter is generated:

			How is it
Parameter	What it means	Value	generated?

failover_policy	Indicates the preference for
	package failover

site_preferred (default)

Other possible value:

site_preferred_manual (The user needs to manually edit the generated configuration file in this case)

auto-created (recommended)

package_name	Name of the Site Controller		Auto-created but
	package		editable by user
critical_package	Indicates the name of a package,	Any package name that is already	User input
	upon whose failure the entire	configured in the cluster
	complex workload set is halted by
	Site Controller

managed_packages	Indicates the name of packages
	that are managed by Site
	Controller

Any package name that is already	User input
configured in the cluster

Appropriate	Indicates the Metrocluster module
Metrocluster module	that will be included in the Site
parameters	Controller package configuration

This module will be dependent on the	Auto-discovered
type of replication pair used by the
complex workload packages:
If it is XP DEVICE GROUP, then
dts/mcxpca will be included along with
its parameters.
If it is SRDF DEVICE GROUP, then
dts/mcsrdf will be included along with
its parameters.
If it is CAEVA DR GROUP then
dts/mccaeva will be included along
with its parameters.

Limitations

•The Site Controller package Easy Deployment feature is not currently supported for a Continentalclusters environment.

•During deployment, the complex workload packages must be in a halted state.

•The complex workload packages that use raw disks over a replication pair will not be supported.

•All the complex workload packages must be modular style packages.

•All the complex workload packages for single Site Controller must use exactly one replication pair.

•The prerequisites and restrictions for Metrocluster XPCA, Metrocluster EMC SRDF, and Metrocluster CAEVA are applicable here as well. Please refer to the section “Prerequisites and restrictions on package Easy Deployment in a Metrocluster environment” for more information.
