Availability Suite Lightweight Resource Groups

Language:

A device group that is controlled by the Availability Suite feature can be added to a protection group. The Geographic Edition software creates a lightweight resource group for each device group.

Note - Each device group controlled by the Availability Suite feature must exist on both partner clusters and must have the same name on both.

The name of a lightweight resource group has the following format:

AVS-device-group-stor-rg

For example, a device group named avsdg that is controlled by the Availability Suite feature has a lightweight resource group named avsdg-stor-rg.

The lightweight resource group collocates the logical host and the device group, a requirement of data replication with the Availability Suite remote mirror feature.

Each lightweight resource group contains two resources:

A logical hostname resource for the local logical host that is used for replication of the device group. One logical hostname resource is required for each cluster for each device group that will be replicated by Availability Suite. Thus if you have two clusters and three device groups that will be replicated, you will need six logical hostnames, three on the local area network of each cluster. The name of this resource has the following format:
```
AVS-device-group-lh
```
An HAStoragePlus resource for controlling the location of the device group with the lightweight resource group. The name of this resource has the format AVS-device-group-stor.

Note - Do not directly update a lightweight resource group or its resources or add them directly to a protection group. Doing so might lead to a failure in Geographic Edition operations.
