sar: can't open /var/adm/sa/sa21

How did you run sar command to get this error message? sar command lets you see the live data. To see historical data, you must have the system usre's cron job setup to run sar every 20 mins (or whatever interval you want) and use sar -f /var/adm/sa/saxx (where xx is the number) to retrieve the data
