9 Monitoring System and Physical Disk Capacity

Overview

The HP 3PAR CLI provides commands to show the amount of used space and available space in
a system. These commands allow you to review space usage information at the system level and
for each physical disk.
Use the following CLI commands to review space usage information:
showpd—displays configuration information about the physical disks in the system.
showspare—displays information about spare chunklets in the system.
showsys—displays an overview of the system's capacity and connectivity.

System Capacity

The HP 3PAR CLI provides detailed views of the system's total capacity, as well as the system's
total capacity by storage device type.

Determining Total System Capacity

To determine system capacity, issue the showsys -space command. The following is an example
of the data returned by issuing this command:
cli% showsys -space

As shown in the example above, system capacity is displayed in MBs. The first line displays the
system's total capacity, which is the sum of the allocated space (Allocated), free space (Free),
and failed space (Failed).
The allocated space includes the following:
