DescriptionProperty
The vendor of the physical storage system exposing the back-end LU.Vendor
The model of the physical storage system exposing the back-end LU.Model
The storage capacity on the back-end LU available for allocation.Capacity
The signature written to the back-end LU by the VSM server when the back-end LU
is configured as a storage pool member. When you add a back-end LU to a storage
pool, the VSM server to which you are connected writes a signature on the back-
end LU, which includes the domain name. The back-end LU now belongs to a
domain and can only be managed by connecting to the VSM server that manages
that domain.
Signature
A free text field. To enter text into this field, right-click the back-end LU in the List
