Parameters 

Parameter	Comments

day_interval integer	Number of days between snapshots. Applicable only when rule type is `every_n_days`.
day_of_month integer	Day of the month for which the snapshot schedule rule applies. Applicable only when rule type is `every_month`. Value should be [1, 31].
days_of_week list / elements=string	Days of the week for which the snapshot schedule rule applies. Applicable only when rule type is `every_week`. Choices: `"SUNDAY"` `"MONDAY"` `"TUESDAY"` `"WEDNESDAY"` `"THURSDAY"` `"FRIDAY"` `"SATURDAY"`
desired_retention integer	The number of days/hours for which snapshot will be retained. When auto_delete is `true`, desired_retention cannot be specified. Maximum desired retention supported is 31 days or 744 hours.
hour integer	The hour when the snapshot will be taken. Applicable for `every_n_days`, `every_week`, `every_month` rule types. For create operation, if hour parameter is not specified, value will be taken as `0`. Value should be [0, 23].
hours_of_day list / elements=integer	Hours of the day when the snapshot will be taken. Applicable only when rule type is `every_day`.
id string	The ID of the snapshot schedule.
interval integer	Number of hours between snapshots. Applicable only when rule type is `every_n_hours`.
minute integer	Minute offset from the hour when the snapshot will be taken. Applicable for all rule types. For a create operation, if minute parameter is not specified, value will be taken as `0`. Value should be [0, 59].
name string	The name of the snapshot schedule. Name is mandatory for a create operation. Specify either name or id (but not both) for any operation.
password string / required	The password of the Unity management server.
port integer	Port number through which communication happens with Unity management server. Default: `443`
retention_unit string	The retention unit for the snapshot. Choices: `"hours"` ← (default) `"days"`
state string / required	Define whether the snapshot schedule should exist or not. Choices: `"absent"` `"present"`
type string	Type of the rule to be included in snapshot schedule. Type is mandatory for any create or modify operation. Once the snapshot schedule is created with one type it can be modified. Choices: `"every_n_hours"` `"every_day"` `"every_n_days"` `"every_week"` `"every_month"`
unispherehost string / required	IP or FQDN of the Unity management server.
username string / required	The username of the Unity management server.
validate_certs aliases: verifycert boolean	Boolean variable to specify whether or not to validate SSL certificate. `true` - Indicates that the SSL certificate should be verified. `false` - Indicates that the SSL certificate should not be verified. Choices: `false` `true` ← (default)

Notes 

Note

Snapshot schedule created through Ansible will have only one rule.
Modification of rule type is not allowed. Within the same type, other parameters can be modified.
If an existing snapshot schedule has more than 1 rule in it, only get and delete operation is allowed.
The check_mode is not supported.
The modules present in this collection named as ‘dellemc.unity’ are built to support the Dell Unity storage platform.
