                                 snapGroupName"] (userLabel="
                                 snapGroupName" |repositoryFullPolicy=(failBaseWrites | purgeSnapImages) |
                                 repositoryFullLimit=
                                 percentValue |autoDeleteLimit=
                                 numberOfSnapImages |rollbackPriority=(lowest | low | medium | high | highest))

Parameters

Parameter	Description
`snapGroup`	The alphanumeric identifier (including - and _) of the snapshot group for which you are setting properties. Enclose the snapshot group name in double quotation marks (" ") inside of square brackets ([ ]).
`userLabel`	The new alphanumeric identifier (including - and _) that you want to give to the snapshot group. Use this parameter when you want to rename the snapshot group. Enclose the new snapshot group name in double quotation marks (" ").
`repositoryFullPolicy`	How you want snapshot image processing to continue if the repository virtual disks for the snapshot image group are full. You can choose to fail writes to the base virtual disk ( `failBaseWrites`) or delete (purge) the snapshot images ( `purgeSnapImages`). The default action is `purgeSnapImages`.
`repositoryFullLimit`	The percentage of repository virtual disk capacity at which you receive a warning that the snapshot image repository virtual disk is nearing full. Use integer values. For example, a value of `70` means 70 percent. The default value is `75`.
`autoDeleteLimit`	The maximum number of snapshot images that you want to automatically delete if you have selected to purge the snapshot images for a repository full policy. Use integer values. The default value is `32`.
`rollBackPriority`	Use this parameter to determine whether system resources should be allocated to the rollback operation at the expense of system performance. Valid values are `highest`, `high`, `medium`, `low`, or `lowest`. A value of `high` indicates that the rollback operation is prioritized over all other host I/O. A value of `lowest` indicates that the rollback operation should be performed with minimal impact to host I/O.

Notes

You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names. Names can have a maximum of 30 characters.

When you use this command, you can specify one or more of the parameters. You do not, however, need to use all of the parameters.
