Configuration Requirements
These requirements apply to Sun Cluster HA for N1 Service Provisioning System only. You must meet these requirements before you proceed with your Sun Cluster HA for N1 Service Provisioning System installation and configuration.
Caution – Your data service configuration might not be supported if you do not adhere to these requirements.
Configure the N1 Grid Service Provisioning System base directory on shared storage on a failover file system
Create the N1 Grid Service Provisioning System base directory on the shared storage. The location for the base directory can reside on a Global File System (GFS) or it can reside on a Failover File System (FFS) with an HAStoragePlus resource. It is best practice to store it on a FFS.
The FFS is required because the Master Server uses the directory structure to store its configuration, logs, deployed applications, database and so on. The Remote agent and the Local Distributor store their caches below the base directory. It is not recommended to store the binaries on the local storage and the dynamic parts of the data on the shared storage.
Note –
It is best practice to mount Global File Systems with the /global prefix and to mount Failover File Systems with the /local prefix.
N1 Grid Service Provisioning System components and dependencies –
You can configure the Sun Cluster HA for N1 Service Provisioning System data service to protect one or more N1 Grid Service Provisioning System instances or components. Each instance or component needs to be covered by one Sun Cluster HA for N1 Service Provisioning System resource. The dependencies between the Sun Cluster HA for N1 Service Provisioning System resource and other necessary resources are described in the following table.
Table 3 Dependencies Between Sun Cluster HA for N1 Service Provisioning System Components in Failover Configurations|
Component |
Dependency |
|---|---|
|
N1 Grid Service Provisioning System resource in a Solaris 10 global zone, zone or in Solaris 9. |
SUNW.HAStoragePlus This dependency is required only, if the configuration uses a failover file system or file systems in a zone. SUNW.LogicalHostName |
|
N1 Grid Service Provisioning System resource in a Solaris 10 failover zone. |
Sun Cluster HA for the Solaris Container boot resource. SUNW.HAStoragePlus SUNW.LogicalHostName — This dependency is required only if the zones boot resource does not manage the zone's IP address. |
Note –
For more detailed information about N1 Grid Service Provisioning System, refer to the product documentation on the docs.sun.com webpage or the documentation delivered with the product.
Configuration and Registration Files
Each component of Sun Cluster HA for N1 Service Provisioning System has configuration and registration files in the directory /opt/SUNWscsps/component-dir/util — The term component-dir stands for the directory names master, localdist or remoteagent. These files let you register the N1 Grid Service Provisioning System component with Sun Cluster.
Within these files, you apply the appropriate dependencies.
Example 1 N1 Grid Service Provisioning System master components configuration and registration file for Sun Cluster
# cd /opt/SUNWscsps/master # # ls -l util total 38 -r-xr-xr-x 1 root bin 913 Jun 6 13:54 db_prep_postgres -r-xr-xr-x 1 root bin 1271 Jun 6 13:54 spsma_config -r-xr-xr-x 1 root bin 7709 Jun 6 13:54 spsma_register -r-xr-xr-x 1 root bin 5276 Jun 6 13:54 spsma_smf_register -r-xr-xr-x 1 root bin 1348 Jun 6 13:54 spsma_smf_remove # more util/spsma_config # # Copyright 2006 Sun Microsystems, Inc.

The spsma_register script validates the variables of the spsma_config script and registers the resource for the master server.
The master server component has an additional script db_prep_postgres. The purpose of this script is to prepare the PostgreSql database of the Master Server for monitoring.
Example 2 N1 Grid Service Provisioning System Remote Agent components configuration and registration file for Sun Cluster
# cd /opt/SUNWscsps/remoteagent # # ls -l util total 34 -r-xr-xr-x 1 root bin 1363 Jun 6 13:54 spsra_config -r-xr-xr-x 1 root bin 7556 Jun 6 13:54 spsra_register -r-xr-xr-x 1 root bin 4478 Jun 6 13:54 spsra_smf_register -r-xr-xr-x 1 root bin 1347 Jun 6 13:54 spsra_smf_remove # more util/spsra_config # # Copyright 2006 Sun Microsystems, Inc.
