Flexible Storage Sharing (FSS) is a feature of Symantec Storage Foundation Cluster File System High Availability (SFCFSHA). FSS is supported in Veritas Operations Manager as follows:
Veritas Operations Manager checks if Cluster Volume Manager (CVM) clusters are FSS capable and if the cluster nodes have the required managed host version (Veritas Operations Manager 6.1 or later) in order to perform FSS operations from Veritas Operations Manager.
Veritas Operations Manager discovers whether FSS is enabled for a disk group and the information is shown in the Management Server console for the disk group. Disk groups must be enabled for FSS before adding network shared disks.
Veritas Operations Manager discovers whether a disk is exported (network shared disk), remote, or neither and will show the FSS state for a disk in the console.
Disk export is an FSS-specific operation performed on a disk that is locally visible to a host to make it visible to all hosts in the CVM cluster. A remote disk is a disk that has been exported from another host in the cluster.
The Management Server console contains wizards for support of the FSS operations of enabling/disabling FSS for an existing disk group and exporting/unexporting disks for shared use in the CVM cluster. Wizards for existing SF operations support FSS operations as needed.
CVM clusters (both FSS capable and non-FSS capable) are listed in the tree in the Server perspective. The cluster view in the Server perspective provides storage visualization views, including how each host in the cluster is using storage, how much is local, how much is remote, and so on. The Create Disk Group operation is available at the cluster level. Other SF operations are available from objects in the selected cluster.
You can create queries for a Cluster object in the Search feature on the Server perspective. For example, you can search for clusters with the attribute FSS Capable.
When you create a volume for a FSS-enabled disk group, you can specify to mirror the volume across hosts. To help validate that mirrored volumes are not based off local storage from a single host, you can register the Cross Enclosure/Host Mirroring policy signature for the hosts.
