Storage pool information—Storage Pool Segment tab
The Storage Pool Segment tab shows the mapping between logical block addresses (LBAs) on each
back-end LU in the storage pool and LBAs on virtual disks and virtual disk segments created from the
selected storage pool.
The mapping information is displayed in a tabular format. Each line in the table represents a mapping
between all or part of a back-end LU and all or part of a virtual disk. When a virtual disk is expanded,
the new part of the virtual disk is represented by a new line in this table. With thin provisioning,
expect a large number of segments because the virtual disk is sparsely populated.

The row number.No
A back-end LU or stripe set on which a virtual disk or virtual disk segment is
mapped. The icon indicates whether the device is a back-end LU or a stripe set,
and the text indicates the name.
Device
The first of the LBAs on the back-end LU that are mapped to a specific virtual disk
or virtual disk segment.
Device Start LBA
The number of LBAs on the back-end LU that are mapped to a specific virtual disk
or virtual disk segment.
LBA Count
The name of a virtual disk created from the storage pool that is mapped to the
back-end LU. An empty value indicates free capacity on a back-end LU.
Virtual Disk
The first LBA of a virtual disk or virtual disk segment.Virtual Disk Start LBA
The time at which VSM allocated this virtual disk or virtual disk segment. A virtual
disk may be comprised of multiple segments, each created at a different time.
Modification Time
The user who last modified the virtual disk properties.Modified By
