The HAStoragePlus resource type can be used to configure the following options.
Coordinate the boot order of disk devices and resource groups. Other resources in the resource group that contain the HAStoragePlus resource are brought online only after the disk device resources become available.
With AffinityOn set to True, enforce colocation of resource groups and device groups on the same node. This enforced colocation enhances the performance of disk-intensive data services.
Monitor entities managed by the HAStoragePlus resource, including global devices, file systems, and ZFS storage pools.
In addition, HAStoragePlus is capable of mounting local and global file systems. For more information, see Planning the Cluster File System Configuration.
See Synchronizing the Startups Between Resource Groups and Device Groups Using HAStoragePlus for information about the relationship between device groups and resource groups.
