Syntax

set snap-pool-policy volume [error autoexpand|deleteoldestsnapshot

|deletesnapshots|haltwrites|notifyonly|nochange] [critical deleteoldestsnapshot

|deletesnapshots|haltwrites|nochange] [autoexpansionsize size[B|KB|MB|GB|TB

|KiB|MiB|GiB|TiB]

]

Parameters volume

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

error autoexpand|deleteoldestsnapshot|deletesnapshots|haltwrites

|notifyonly|nochange

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

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 increment 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.

Example Set the error policy to autoexpand and the automatic expansion size to 10 GB for snap pool SP1:

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

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