To a protection group, you can add a device group that is controlled by the Sun StorageTek Availability Suite software. The Sun Cluster Geographic Edition software creates a lightweight resource group for each device group. The name of a lightweight resource group has the following format:
AVSdevicegroupname-stor-rg
For example, a device group named avsdg that is controlled by the Sun StorageTek Availability Suite 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 StorageTek Availability Suite 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 has the following format:
SSEdevicegroup-lh |
An HAStoragePlus resource for controlling the collocation of the device group with the lightweight resource group. The name of this resource has the format AVSdevicegroupname-stor.
For more information about lightweight resource groups, see the Sun StorageTek Availability Suite documentation.
