| Name | Type | Description | Notes |
|---|---|---|---|
| dryRun | Boolean | If true, checks whether you have the required permissions to perform the action. | [optional] |
| iops | Integer | Cold volume: the new number of I/O operations per second (IOPS). This parameter can be specified only if you update an `io1` volume or if you change the type of the volume for an `io1`. This modification is instantaneous. <br /> Hot volume: the new number of I/O operations per second (IOPS). This parameter can be specified only if you update an `io1` volume. This modification is not instantaneous. <br /><br /> The maximum number of IOPS allowed for `io1` volumes is `13000` with a maximum performance ratio of 300 IOPS per gibibyte. | [optional] |
| size | Integer | Cold volume: the new size of the volume, in gibibytes (GiB). This value must be equal to or greater than the current size of the volume. This modification is not instantaneous. <br /> Hot volume: you cannot change the size of a hot volume. | [optional] |
| volumeId | String | The ID of the volume you want to update. | |
| volumeType | String | Cold volume: the new type of the volume (`standard` | `io1` | `gp2`). This modification is instantaneous. If you update to an `io1` volume, you must also specify the `Iops` parameter.<br /> Hot volume: you cannot change the type of a hot volume. | [optional] |
