Determining the Memory and Disk Space on a Solaris System

If you need to determine the amount of memory in a Solaris system, you can use the prtconf command. The second line of output will show the amount of memory in the system.
# prtconf
System Configuration:  Sun Microsystems  sun4u
Memory size: 384 Megabytes
System Peripherals (Software Nodes):

SUNW,Ultra-5_10
...

Or you can use prtconf | grep Memory to get just the amount of memory in the system.

If you need to determine the disk space in the system you can use this soldiskspace BASH script to display the disk space in GigaBytes (GB). You may need to modify the first line in the script to point to the actual location of bash on your system, e.g. /usr/local/bin/bash on Solaris 2.7 systems. The script uses the prtvtoc command and is based on the BASH script provided by Sandra Henry-Stocker, ITworld.com in an article titled Calculating overall disk space published on December 23, 2004 on ITworld.com . A full explanation of how the script works is available in the article.

The script must be run as root. To use the script, issue the command chmod 700 soldiskspace to make the script executable.

# ./soldiskspace
Disks:
    /dev/rdsk/c0t0d0s2: 8 Gbytes
    TOTAL: 8 GB

Zip file for script: soldiskspace.zip

An alternative method of determing the disk space on a system is to use iostat -En. Using that command on the same system as used in the example above shows the disk space in the second line of output below. The command also shows the manufacturer and model number for the CD-ROM drive in the system. The size value should be ignored for the CD-ROM drive.

# iostat -En
