Description

The Start-BrokerRebootCycle cmdlet is used to create and start a reboot cycle for each desktop group that contains machines from the specified catalog. For a given desktop group, only the machines from the target catalog are rebooted and any machines from other catalogs are not rebooted.

Creating a reboot cycle for catalog ensures that all machines in the catalog are running the most recent image for the catalog.

Examples

EXAMPLE 1

Starts a new reboot cycle for each desktop group containing machines from the catalog “SampleCatalog”. Each reboot cycle has a duration of six hours. Fifteen minutes prior to rebooting a machine, the message “Save your work” is displayed in each active user session.

Get-BrokerCatalog -Name "SampleCatalog" | Start-BrokerRebootCycle -RebootDuration 240 -WarningMessage "Save your work" -WarningDuration 15
<!--NeedCopy-->

EXAMPLE 2

Starts a new reboot cycle for each desktop group containing machines from the catalog “SampleCatalog”. Fifteen, ten and five minutes prior to rebooting each machine, the message “Rebooting in %m% minutes.” will be displayed in each user session with the pattern ‘%m%’ replaced with the number of minutes until the reboot.

Get-BrokerCatalog -Name "SampleCatalog" | Start-BrokerRebootCycle -WarningMessage "Rebooting in %m% minutes." -WarningDuration 15 -WarningRepeatInterval 5

Parameters

-InputObject

Creates a reboot cycle for each desktop group that contains machines from this input catalog SDK object. The catalogs can be specified using UID values, name values (including wildcards) or catalog objects.

Type: Catalog[]
Position: 2
Default value: None
Required: True
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-RebootDuration

Approximate maximum duration in minutes over which the reboot cycle runs.

Type: Int32
Position: Named
Default value: None
Required: True
Accept pipeline input: False
Accept wildcard characters: False

-WarningDuration

Time in minutes prior to a machine reboot at which a warning message is displayed in all user sessions on that machine. If the warning duration value is zero then no message is displayed. In some cases the time required to process a reboot cycle may exceed the RebootDuration time by up to the WarningDuration value; Citrix recommends that the WarningDuration is kept small relative to the RebootDuration value.

Type: Int32
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-WarningTitle

The window title used when showing the warning message in user sessions on a machine scheduled for reboot.

Type: String
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False
Length range: 1 to 64

-WarningMessage

Warning message displayed in user sessions on a machine scheduled for reboot. If the message is blank then no message is displayed. The optional pattern ‘%m%’ is replaced by the number of minutes until the reboot.

Type: String
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False
Length range: 1 to 512

-WarningRepeatInterval

Number of minutes to wait before showing the reboot warning message again.

Type: Int32
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-LoggingId

Specifies the identifier of the high level operation that this cmdlet call forms a part of. Desktop Studio and Desktop Director typically create High Level Operations. PowerShell scripts can also wrap a series of cmdlet calls in a High Level Operation by way of the Start-LogHighLevelOperation and Stop-LogHighLevelOperation cmdlets.

Type: Guid
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False
