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 Used : 1024 Unused : 84992 Admin : 65536 Used : 512 Unused : 65024 Unmapped : 0 System : 180224 Internal : 110592 Spare : 69632 Used : 0 Unused : 69632 Free : 197632 Initialized : 197632 Uninitialized : 0 Unavailable : 0 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.
