Description

Property

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
area and select Manage > Edit Comment.

capacity iSCSI command and is slightly larger than the capacity available to VSM.

Real Capacity

The size of the smallest writable element on the back-end LU, in bytes.

Sector Size

The unique hardware ID of the back-end LU.

Serial Number

The time at which VSM first detected the back-end LU.

Creation Time

The time of the last modification to the back-end LU configuration in VSM. The
modification may be the addition or removal of the back-end LU from a storage
pool.

Modification Time

ation in VSM.
