To use disks that are not physically shared across all nodes of a Cluster Volume Manager cluster, the disks must first be exported for network sharing. Exporting a device makes the device available to all nodes in the cluster. The export is required for SAN disks as well as local disks to make them fully shared with any new nodes that may join the cluster. Exported disks can be added only to a disk group that is enabled for Flexible Storage Sharing (FSS).
Boot disks, opaque disks, disks that are part of imported or deported disk groups, and non-Storage Foundation (VxVM) disks cannot be exported.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.
To export disks for Flexible Storage Sharing
You can also perform this operation when viewing disks on a host.
You can also select multiple disks at a time for export.
Once a disk is exported, you can view the associated remote disks on the Disks tab.
You can add the exported disk to a shared disk group that has FSS enabled. You can enable FSS while creating a shared disk group or using the Set/Unset FSS operation on an existing disk group.
See Enabling or disabling Flexible Storage Sharing on existing shared disk groups.
To un-export disks previously exported for Flexible Storage Sharing
You can also perform this operation when from a host context.
Once a disk is un-exported, it is no longer visible to other nodes in the cluster as available storage.
