Parameters error autoexpand|deleteoldestsnapshot|deletesnapshots|haltwrites

|notifyonly|nochange

Optional. The policy to invoke when the error threshold level of snap-pool usage is reached.

• autoexpand: Automatically expand the snap pool using the autoexpansionsize value.

• deleteoldestsnapshot: Delete the oldest snapshot.

• nochange: Take no action.

critical deleteoldestsnapshot|deletesnapshots|haltwrites|nochange

Optional. Specifies the policy to invoke when the critical threshold level of snap-pool usage is

reached.

autoexpansionsize size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]

The amount by which the snap pool will be automatically expanded when the threshold level is

reached. The value uses the current base, as shown by set cli-parameters. The unit can be specified

as follows:

• If base 2 is in use: B (bytes), KiB (kibibytes), MiB (mebibytes), or GiB (gibibytes)

• If base 10 is in use: B (bytes), KB (kilobytes), MB (megabytes), or GB (gigabytes)

If no unit is specified, the unit is blocks.

snap-pool

Name or serial number of the snap pool to set the policy for. For syntax, see Command syntax.

Example Set snap pool SP1 to automatically expand by 10 GB when its error threshold is reached:

# set snap-pool-policy error autoexpand autoexpansionsize 10GB SP1

Success: Command completed successfully. - The snap-pool policy was changed.
