Function Set-UnitySnapSchedule { <# .SYNOPSIS Modifies snapshot schedule parameters. .DESCRIPTION Modifies snapshot schedule parameters. You can add or delete rules. Rules can be added one at a time. You need to have an active session with the array. .NOTES Written by Erwan Quelin under MIT licence - https://github.com/equelin/Unity-Powershell/blob/master/LICENSE .LINK https://github.com/equelin/Unity-Powershell .PARAMETER Session Specify an UnitySession Object. .PARAMETER Confirm If the value is $true, indicates that the cmdlet asks for confirmation before running. If the value is $false, the cmdlet runs without asking for user confirmation. .PARAMETER WhatIf Indicate that the cmdlet is run only to display the changes that would be made and actually no objects are modified. .PARAMETER ID ID of the snapshot Schedule or snapshot Schedule Object. .PARAMETER addRules Rules to add to the snapshot schedule. .PARAMETER removeRuleIds ID of the rules to remove from the snapshot schedule. .PARAMETER type Type of snapshot schedule rule. Values are: - N_HOURS_AT_MM: Snap every <interval> hours, at <minutes> past the hour. Supported parameters: interval (required), minutes (optional, default 0). - DAY_AT_HHMM: Specify a list of <hour[,...]> to snap one or more times each day at <minutes> past the hour. Supported parameters: hours (at least one required), minutes (optional). - N_DAYS_AT_HHMM: Snap every <interval> days at the time <hours>:<minutes>. Supported Parameters: interval (required), hours (optional, exactly one), minutes (optional). - SELDAYS_AT_HHMM: Snap on the selected <daysOfWeek>, at the time <hours>:<minutes>. Supported parameters: daysOfWeek (at least one required), hours (optional, default 0), minutes (optional, default 0). - NTH_DAYOFMONTH_AT_HHMM: Snap on the selected <daysOfMonth>, at the time <hours>:<minutes>. Supported parameters: daysOfMonth (at least one required), hours (optional, default 0), minutes (optional, default 0). .PARAMETER minute Minute frequency for the snapshot schedule rule. .PARAMETER hours Hourly frequency for the snapshot schedule rule. .PARAMETER daysOfWeek Days of the week for which the snapshot schedule rule applies. .PARAMETER daysOfMonth Days of the month for which the snapshot schedule rule applies. .PARAMETER interval Number of days or hours between snaps, depending on the rule type. .PARAMETER isAutoDelete Indicates whether the system can automatically delete the snapshot based on pool automatic-deletion thresholds. Values are: - $True: System can delete the snapshot based on pool automatic-deletion thresholds. - $False: System cannot delete the snapshot based on pool automatic-deletion thresholds. .PARAMETER retentionTime (Applies when the value of the isAutoDelete attribute is false.) Period of time in seconds for which to keep the snapshot. .PARAMETER accessType For a file system or VMware NFS datastore snapshot schedule, indicates whether the snapshot created by the schedule has checkpoint or protocol type access .EXAMPLE Set-UnitySnapSchedule -ID 'snapSch_6' -addRules -Type N_HOURS_AT_MM -Interval 12 -Minutes 30 Add rule to snapshot schedule with ID 'snapSch_6'. Snap every 12 hours, at 30 minutes past the hour. .EXAMPLE Set-UnitySnapSchedule -ID 'snapSch_6' -removeRuleIds 'SchedRule_11' Remove rule ID 'SchedRule_11' to snapshot schedule with ID 'snapSch_6'. #> [CmdletBinding(SupportsShouldProcess = $True,ConfirmImpact = 'High',DefaultParameterSetName="addRules")] Param ( #Default Parameters [Parameter(Mandatory = $false,HelpMessage = 'EMC Unity Session')] $session = ($global:DefaultUnitySession | where-object {$_.IsConnected -eq $true}), [Parameter(Mandatory = $true,ParameterSetName="addRules",Position = 0,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True,HelpMessage = 'ID of the snapshot Schedule or snapshot Schedule Object.')] [Parameter(Mandatory = $true,ParameterSetName="removeRuleIds",Position = 0,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True,HelpMessage = 'ID of the snapshot Schedule or snapshot Schedule Object.')] [String[]]$ID, # Add rules [Parameter(Mandatory = $true,ParameterSetName="addRules",HelpMessage = 'Unique identifiers of the rules to remove from the snapshot schedule.')] [switch]$addRules, [Parameter(Mandatory = $true,ParameterSetName="addRules",HelpMessage = 'Type of snapshot schedule rule.')] [ScheduleTypeEnum]$type, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Minute frequency for the snapshot schedule rule.')] [UInt32]$minute, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Hourly frequency for the snapshot schedule rule.')] [UInt32[]]$hours, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Days of the week for which the snapshot schedule rule applies.')] [DayOfWeekEnum[]]$daysOfWeek, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Days of the month for which the snapshot schedule rule applies.')] [UInt32]$daysOfMonth, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Number of days or hours between snaps, depending on the rule type.')] [UInt32]$interval, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = 'Indicates whether the system can automatically delete the snapshot based on pool automatic-deletion thresholds.')] [bool]$isAutoDelete, [Parameter(Mandatory = $false,ParameterSetName="addRules",HelpMessage = '(Applies when the value of the isAutoDelete attribute is false.)
