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)
package_name | Name of the Site Controller |
| |
| 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 | |
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.
