Sun StorEdge Availability Suite 3.2.1 Lightweight Resource Groups

A device group that is controlled by Sun StorEdge Availability Suite 3.2.1 might be added to a protection group. Sun Cluster Geographic Edition software then creates a lightweight resource group for each device group. The name of the lightweight resource group has the following format:

AVS-device-group-name-stor-rg

For example, a device group named avsdg that is controlled by the Sun StorEdge Availability Suite 3.2.1 software 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 Sun StorEdge Availability Suite 3.2.1 remote mirror software.

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. The name of this resource is the same as the hostname of the local logical host.

• A HAStoragePlus resource for controlling the collocation of the device group with the lightweight resource group. The name of this resource has the format AVS-device-group-name-stor.

For more information about lightweight resource groups, see the Sun StorEdge Availability Suite 3.2.1 documentation.
