New-AzWvdScalingPlan -Schedule wrong time format (should be HH:mm)

[tmmjelde]

Description

This is an example of a "working" command: New-AzWvdScalingPlan -ResourceGroupName ResourceGroupName -Name Name -Location 'westeurope' -HostPoolType 'Pooled' -TimeZone 'W. Europe Standard Time' -Schedule @( @{ 'name' = 'Weekends'; 'daysOfWeek' = @('Saturday', 'Sunday'); 'rampUpStartTime' = '1900-01-01T06:30:00Z'; 'rampUpLoadBalancingAlgorithm' = 'BreadthFirst'; 'rampUpMinimumHostsPct' = 10; 'rampUpCapacityThresholdPct' = 80; 'peakStartTime' = '1900-01-01T09:00:00Z'; 'peakLoadBalancingAlgorithm' = 'DepthFirst'; 'RampDownStartTime' = '1900-01-01T18:00:00Z'; 'rampDownLoadBalancingAlgorithm' = 'DepthFirst'; 'rampDownMinimumHostsPct' = 10; 'rampDownCapacityThresholdPct' = 80; 'rampDownForceLogoffUser' = $false; 'rampDownWaitTimeMinute' = 30; 'rampDownNotificationMessage' = 'You will be logged off in 30 min. Make sure to save your work.'; 'rampDownStopHostsWhen' = 'ZeroSessions'; 'offPeakStartTime' = '1900-01-01T20:00:00Z'; 'offPeakLoadBalancingAlgorithm' = 'DepthFirst'; } )

Creation "works" just fine. No errors in Powershell. However, go into the Azure portal and review the schedule. It will tell you the format is wrong for the following: rampUpStartTime, peakStartTime, RampDownStartTime, offPeakStartTime

These require HH:mm format. As such, a good example would be this:

New-AzWvdScalingPlan -ResourceGroupName ResourceGroupName -Name Name -Location 'westeurope' -HostPoolType 'Pooled' -TimeZone 'W. Europe Standard Time' -Schedule @( @{ 'name' = 'Weekends'; 'daysOfWeek' = @('Saturday', 'Sunday'); 'rampUpStartTime' = '06:30'; 'rampUpLoadBalancingAlgorithm' = 'BreadthFirst'; 'rampUpMinimumHostsPct' = 10; 'rampUpCapacityThresholdPct' = 80; 'peakStartTime' = '09:00'; 'peakLoadBalancingAlgorithm' = 'DepthFirst'; 'RampDownStartTime' = '18:00'; 'rampDownLoadBalancingAlgorithm' = 'DepthFirst'; 'rampDownMinimumHostsPct' = 10; 'rampDownCapacityThresholdPct' = 80; 'rampDownForceLogoffUser' = $false; 'rampDownWaitTimeMinute' = 30; 'rampDownNotificationMessage' = 'You will be logged off in 30 min. Make sure to save your work.'; 'rampDownStopHostsWhen' = 'ZeroSessions'; 'offPeakStartTime' = '20:00'; 'offPeakLoadBalancingAlgorithm' = 'DepthFirst'; } )

But this fails in Powershell.

Please change the powershell requirements to support HH:mm format, as the Azure portal specifies is required.

Also, this parameter is mislabeled: rampDownWaitTimeMinute should be rampDownWaitTimeMinutes. Check the ARM template to verify this.
