You can customize the size of your RAID groups based on your requirements for data availability, performance, and disk utilization.
Considerations
You change the size of RAID groups on a per-aggregate basis, by setting the raidsize aggregate option. You cannot change the size of individual RAID groups.
The following list outlines some facts about changing the
raidsize aggregate option:
- If you increase the raidsize option, more disks will be added to the most recently created RAID group until it reaches the new size.
- All other existing RAID groups in that aggregate remain the same size, unless you explicitly add disks to them.
- You cannot decrease the size of already created RAID groups.
- The new size applies to all subsequently created RAID groups in that aggregate.
Step
-
Enter the following command: aggr options aggr_name raidsize size
Example
The following command changes the raidsize setting of the aggregate aggr3 to 16 disks:aggr options aggr3 raidsize 16
