Activating and Deactivating a Protection Group

This section describes the following tasks:

• How to Activate a Sun StorageTek Availability Suite Protection Group

• How to Deactivate a Sun StorageTek Availability Suite Protection Group

When you activate a protection group, it assumes the role that you assigned to it during configuration.

For more information about configuring protection groups, see How to Create and Configure a Sun StorageTek Availability Suite Protection Group.

How to Activate a Sun StorageTek Availability Suite Protection Group

Before You Begin

You can activate a protection group in the following ways:

• Globally, which activates a protection group on both clusters where the protection group has been configured

• On the primary cluster only

• On a secondary cluster only

When you activate a protection group, the data replication product you are using determines the clusters on which data replication can start. For example, the Sun StorageTek Availability Suite software allows data replication to start only from the primary cluster. So, if you activate a protection group from the secondary cluster, data replication does not start.

1. Log in to a cluster node.

   You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Geographic Edition Software and RBAC in Oracle Solaris Cluster Geographic Edition System Administration Guide.

2. Activate the protection group.

   This command activates the protection group on the local cluster.

   When you activate a protection group on the primary cluster, its application resource groups are also brought online.

   # geopg start -e scope [-n] AVSprotectiongroup

   -e scope

   Specifies the scope of the command.

   If the scope is Local, then the command operates on the local cluster only. If the scope is Global, the command operates on both clusters that deploy the protection group.

   ---

   Note - The property values, such as Global and Local, are not case sensitive.

   ---

   -n

   Prevents the start of data replication at protection group startup.

   If you omit this option, the data replication subsystem starts at the same time as the protection group and the command performs the following operations on each device group in the protection group:

   • Verifies that the role configured for the replication resource is the same as the role of the protection group on the local cluster.

   • Verifies that the role of the volume sets associated with the device group is the same as the role of the protection group on the local cluster.

   • If the role of the protection group on the local cluster is secondary, unmounts the local volumes defined in all volume sets associated with the device group.

   • If the role of the protection group on the local cluster is primary, enables the autosynchronization feature of the Sun StorageTek Availability Suite remote mirror software. Also, resynchronizes the volume sets associated with the device group.

   AVSprotectiongroup

   Specifies the name of the protection group.

   The geopg start command uses the clresourcegroup -eM -g resourcegroup command to bring resource groups and resources online. For more information about using this command, see the clresourcegroup(1CL) man page.

   The geopg start command performs the following actions if the role of the protection group is primary on the local cluster:

   • The command runs a script that is defined in the RoleChange_ActionCmd.

   • The command brings the application resource groups in the protection group online on the local cluster.

   • If the application resource group is a failover type resource group that shares affinities with a device group in the same protection group, the command adds strong, positive affinities and failover delegation between the application resource group and the lightweight resource group.

     The application resource group must not have strong, positive affinities with failover delegation. Otherwise, the attempt to add strong, positive affinities with failover delegation with the lightweight resource group will fail.

   • The command creates strong dependencies between the HAStoragePlus resource in the application resource group and the HAStoragePlus resource in the lightweight resource group for this device group.

   If the command fails, the Configuration status might be set to Error, depending on the cause of the failure. The protection group remains deactivated, but data replication might be started and some resource groups might be brought online. Run the geoadm status command to obtain the status of your system.

   If the Configuration status is set to Error, revalidate the protection group by using the procedures that are described in How to Validate a Sun StorageTek Availability Suite Protection Group.

Example 2-12 Activating a Sun StorageTek Availability Suite Protection Group Globally

This example activates a protection group globally.

# geopg start -e global avspg

Example 2-13 Activating a Sun StorageTek Availability Suite Protection Group Locally

This example activates a protection group on a local cluster only. This local cluster might be a primary cluster or a secondary cluster, depending on the role of the cluster.

# geopg start -e local avspg

How to Deactivate a Sun StorageTek Availability Suite Protection Group

Before You Begin

You can deactivate a protection group in the following ways:

• Globally, meaning you deactivate a protection group on both the primary and the secondary cluster where the protection group is configured

• On the primary cluster only

• On the secondary cluster only

The result of deactivating a protection group on primary or secondary cluster depends on the type of data replication you are using. If you are using Sun StorageTek Availability Suite software, data replication can be stopped only from the primary cluster. So, when you deactivate a protection group on the secondary cluster, this deactivate command does not stop data replication.

1. Log in to a cluster node.

   You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Geographic Edition Software and RBAC in Oracle Solaris Cluster Geographic Edition System Administration Guide.

2. Deactivate the protection group.

   This command deactivates the protection group on all nodes of the local cluster.

   When you deactivate a protection group, its application resource groups are also unmanaged.

   # geopg stop -e scope [-D] protectiongroupname 

   -e scope

   Specifies the scope of the command.

   If the scope is local, then the command operates on the local cluster only. If the scope is global, the command operates on both clusters where the protection group is deployed.

   ---

   Note - The property values, such as global and local, are not case sensitive.

   ---

   -D

   Specifies that only data replication should be stopped and the protection group should be online.

   If you omit this option, the data replication subsystem and the protection group are both stopped. If the role of the protection group on the local cluster is primary, omitting the -d option also results in the following actions:

   • Removal of resource group affinities and resource dependencies between the application resource groups in the protection group and the internal resource group

   • Taking the application resource groups offline and putting them in an Unmanaged state

   protectiongroupname

   Specifies the name of the protection group.

   If the role of the protection group is primary on the local cluster, the geopg stop command disables the autosynchronization of each device group and places the volume sets into logging mode.

   If the geopg stop command fails, run the geoadm status command to see the status of each component. For example, the Configuration status might be set to Error depending on the cause of the failure. The protection group might remain activated even though some resource groups might be unmanaged. The protection group might be deactivated with data replication running.

   If the Configuration status is set to Error, revalidate the protection group by using the procedures described in How to Validate a Sun StorageTek Availability Suite Protection Group.

Example 2-14 Deactivating a Sun StorageTek Availability Suite Protection Group on All Clusters

This example deactivates a protection group on all clusters.

# geopg stop -e global avspg

Example 2-15 Deactivating a Sun StorageTek Availability Suite Protection Group on a Local Cluster

This example deactivates a protection group on the local cluster.

# geopg stop -e local avspg

Example 2-16 Stopping Sun StorageTek Availability Suite Data Replication While Leaving the Protection Group Online

This example stops only data replication on a local cluster.

# geopg stop -e local -D avspg

If the administrator decides later to deactivate both the protection group and its underlying data replication subsystem, the administrator can rerun the command without the -d option.

# geopg stop -e local avspg

Example 2-17 Deactivating a Sun StorageTek Availability Suite Protection Group While Keeping Application Resource Groups Online

This example keeps online two application resource groups, apprg1 and apprg2, while deactivating their protection group, avspg.

1. Remove the application resource groups from the protection group.

   # geopg remove-resource-group apprg1,apprg2 avspg

2. Deactivate the protection group.

   # geopg stop -e global avspg
