Adding disks to a disk-bound aggregate

If you have a single traditional volume or single-aggregate storage system, you can determine the fraction of time that the busiest disk is active and add disks to the traditional volume or aggregate if necessary.

Steps

1. Enter the following command to determine the fraction of time that the busiest disk is active: sysstat -u
2. If the fraction is greater than 80 percent, add disks to the traditional volume or aggregate by entering the following command: aggr add aggrname disk-list

   For more information about the aggr add command, see the na_aggr(1) man page.
