Destroying aggregates

About destroying aggregates

When you destroy an aggregate, Data ONTAP converts its parity disk and all its data disks back into hot spares. You can then use the spares in other aggregates and other storage systems. Before you can destroy an aggregate, you must destroy all of the FlexVol volumes contained by that aggregate.

There are two reasons to destroy an aggregate:

You no longer need the data it contains.
You copied its data to reside elsewhere.
Attention
If you destroy an aggregate, all the data in the aggregate is destroyed and no longer accessible, unless you undestroy it before any of the data is corrupted.

Note
You can destroy a SnapLock Enterprise aggregate at any time; however, you cannot destroy a SnapLock Compliance aggregate until the retention periods for all data contained in it have expired.

Destroying an aggregate

To destroy an aggregate, complete the following steps.

Step	Action
1	Take all FlexVol volumes offline and destroy them by entering the following commands for each volume: vol offline vol_name vol destroy vol_name
2	Take the aggregate offline by entering the following command: aggr offline aggr_name aggr_name is the name of the aggregate that you intend to destroy. Example `system> aggr offline aggr_A` Result The following message is displayed. Aggregate 'aggr_A' is now offline.
3	Destroy the aggregate by entering the following command: aggr destroy aggr_name aggr_name is the name of the aggregate that you are destroying and whose disks will be converted to hot spares. Example `system> aggr destroy aggr_A` Result The following message is displayed. Are you sure you want to destroy this aggregate ? After typing `y`, the following message is displayed. Aggregate 'aggr_A' destroyed.

Step

Action

Take all FlexVol volumes offline and destroy them by entering the following commands for each volume:

vol offline vol_name

vol destroy vol_name

Take the aggregate offline by entering the following command:

aggr offline aggr_name

aggr_name is the name of the aggregate that you intend to destroy.

Example

system> aggr offline aggr_A

Result

The following message is displayed.

Aggregate 'aggr_A' is now offline.

Destroy the aggregate by entering the following command:

aggr destroy aggr_name

aggr_name is the name of the aggregate that you are destroying and whose disks will be converted to hot spares.

Example

system> aggr destroy aggr_A

Result

The following message is displayed.

Are you sure you want to destroy this aggregate ?

After typing y, the following message is displayed.
