Determining the amount of RAM installed on an AIX system can be useful for troubleshooting performance issues or planning upgrades. Several commands can be used to check RAM size in AIX, including “lsattr -El”, “prtconf”, and “vmstat”.
The “lsattr -El” command provides detailed information about the system’s hardware, including the amount of RAM installed. The “prtconf” command displays a summary of the system’s configuration, including the amount of RAM installed. The “vmstat” command provides information about the system’s memory usage, including the amount of RAM installed.
