About thin reclamation with Veritas InfoScale product components in the VMware guest
Veritas InfoScale product components support reclamation of the unused storage on thin-reclamation capable arrays and LUNs. InfoScale Solutions automatically discover LUNs that support thin reclamation.
If you configure Veritas InfoScale product components in Raw Device Mapping mode, Veritas InfoScale product components can control the storage in the VMware guests directly. With this configuration, you can use the thin reclamation functionality of Veritas InfoScale product components on the VMware guest. This configuration may limit some VMware functionality such as vMotion. You cannot use the thin reclamation functionality of Veritas InfoScale product components if the storage is configured in VMDK mode.Veritas InfoScale product components do not have the visibility to the physical storage under the VMware guest to reclaim the freed storage.
For more information about thin reclamation, see Storage Foundation Cluster File System High Availability Administrator's Guide or Storage Foundation Administrator's Guide.
