To make an application highly available, the application must be managed as a resource in an application resource group.
The initial registration of the protection group is performed with the zfssa_geo_register script. This section explains how to manage the application resource groups on their own.
All the entities you configure for the application resource group on the primary cluster, such as application data resources, application configuration files, and the resource groups, must be replicated manually on the secondary cluster. The resource group names must be identical on both clusters. Also, the data that the application resource uses must be replicated on the secondary cluster.
This section contains information about deleting an application resource group from an Oracle ZFS Storage Appliance protection group.
You can remove an application resource group from a protection group without altering the state or contents of an application resource group.
Before You Begin
Ensure that the following conditions are met:
The protection group is defined on the local cluster.
The resource group to be removed is part of the application resource groups of the protection group.
For more information about RBAC, see Securing Geographic Edition Software in Oracle Solaris Cluster Geographic Edition Installation and Configuration Guide.
# chmod A+user:username:rwx:allow /var/cluster/geo
The /var/cluster/geo directory must have the correct access control lists (ACL) applied for compatibility between the Geo Management RBAC rights profile and Oracle ZFS Storage Appliance software.
# geopg remove-resource-group application-resource-group protection-group
Specifies the name of an application resource group. You can specify more than one resource group in a comma-separated list.
Specifies the name of the protection group.
The command removes an application resource group from a protection group on the local cluster. If the partner cluster contains a protection group of the same name, the command also removes the application resource group from the protection group on the partner cluster.
The following example removes two application resource groups, apprg1 and apprg2, from the zfssa-pg protection group.
# geopg remove-resource-group apprg1,apprg2 zfssa-pg
Troubleshooting
If the remove operation is unsuccessful on the local cluster, the configuration of the protection group is not modified. Otherwise, the configuration status is set to OK on the local cluster.
If the configuration status is OK on the local cluster but the remove operation is unsuccessful on the partner cluster, the configuration status is set to Error on the partner cluster.
