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
--------System Capacity (MB)---------
Total Capacity : 557056
Allocated : 359424
Volumes : 179200
Base Volumes : 27648
User : 27648
Copy : 0
Admin : 0
CPGs (TPVVs & CPVVs) : 151552
Copy : 86016

Failed : 0
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:
• All base volumes and the volumes’ user, copy, and administration spaces.
• Provisioned groups and volumes, and their used and unused copy and administration spaces.
