24 Managing Data Allocation
The Layout Grid Manager allows you to view layout grids showing patterns of virtual volume,
Common Provisioning Group (CPG), logical disk, and physical disk usage. These grids can be
used to monitor resource allocation.
NOTE: Logical disk information only appears if you have set your preferences in the HP 3PAR
Management Console to display logical disk information. See “Setting Global Preferences”
(page 412) .
The following topics discuss each layout grid:
“Viewing Layout Information for All Systems in the Layout Grid Manager” (page 333)
The following figure describes the structure of each layout grid:
All types of chunklet grid screens share the same basic features:
The far left column lists all physical disks in the storage server using the format:
<cage_ID>:<magazine_position>:<disk_position>
<cage_ID> can be 0 (left side of the drive chassis) or 1 (right side of the drive chassis).
<magazine_position> can be 0, 1, 2, 3, or 4.
<disk_position> can be 0, 1, 2, 3, or 4, where 0 is the position closest to the backplane.
Each row represents the storage space of the disk indicated in the left column, with each cell in
the grid representing one chunklet, or 256 megabytes.
Markers indicating the quantity of chunklets in multiples of 10 appear along the top of the grid.
