Update-SCService

Updates a VMM service instance.

Description

The Update-SCService cmdlet updates an instance of a System Center Virtual Machine Manager (VMM) service. There are two servicing types you can use: conventional servicing and image-based servicing. 

Conventional servicing applies updates to deployed virtual machines in place, without redeploying the service. While fast, it does nota llow changing a virtual hard disk, removing network adapters, or changing operating system settings (except for Windows Server roles and features). 

Image-based servicing deploys new virtual machines to the service with the updates. This type of servicing is used most often after updating the VHD for a tier, such as applying software updates to the program disk.

Parameters

Service

Required? true
Accept Pipeline Input? true (ByValue)
Position? named 
Specifies a VMM service object.

JobVariable

Required? false
Accept Pipeline Input? false
Position? named 
Specifies that job progress is tracked and stored in the variable named by this parameter.

PROTipID

Required? false
Accept Pipeline Input? false
Position? named 
Specifies the ID of the PRO tip that triggered this action. This allows for auditing of PRO tips.

RunAsynchronously

Required? false
Accept Pipeline Input? false
Position? named 
Indicates that the job runs asynchronously so that control returns to the command shell immediately.

ShowActions

Required? false
Accept Pipeline Input? false
Position? named 
Displays all servicing and orchestration actions that will be performed. This parameter is useful for debugging.

VMMServer

Required? false
Accept Pipeline Input? false
Position? named 
Specifies a VMM server object.

Service

Required? true
Accept Pipeline Input? true (ByValue)
Position? named 
Specifies a VMM service object.

WhatIf

Required? true
Accept Pipeline Input? false
Position? named 
Describes what would happen if you executed the command without actually executing the command.

JobVariable

Required? false
Accept Pipeline Input? false
Position? named 
Specifies that job progress is tracked and stored in the variable named by this parameter.

PROTipID

Required? false
Accept Pipeline Input? false
Position? named 
Specifies the ID of the PRO tip that triggered this action. This allows for auditing of PRO tips.

RunAsynchronously

Required? false
Accept Pipeline Input? false
Position? named 
Indicates that the job runs asynchronously so that control returns to the command shell immediately.

VMMServer

Required? false
Accept Pipeline Input? false
Position? named 
Specifies a VMM server object.

Requires a VMM service object, which can be retrieved using the Get-SCService cmdlet.

Examples

1: Update a service by using conventional servicing. 
PS C:\> $Service = Get-SCService -Name "Service01"
PS C:\> $SvcTemplate = Get-SCServiceTemplate -Name "ServiceTemplate01"
PS C:\> $PendingTemplate = New-SCServiceTemplate -ServiceTemplate $SvcTemplate -Name "ServiceTemplate01" -Release "RTM"
PS C:\> Set-SCService -Service $Service -PendingServiceTemplate $PendingTemplate
PS C:\> Update-SCService -Service $Service

The first command gets the service object named Service01, which is a deployed service, and stores the object in the $Service variable.

The second command gets the service template object named ServiceTemplate01 and stores the object in the $SvcTemplate variable.

The third command creates an RTM release of the service template stored in $SvcTemplate.

The fifth command sets the pending template on the service instance to the updated service template stored in $PendingTemplate.

The last command updates Service01.
2: Update a service by using image-based servicing. 
PS C:\> $Service = Get-SCService -Name "Service02"
PS C:\> $SvcTemplate = Get-SCServiceTemplate -Name "ServiceTemplate02"
PS C:\> $PendingTemplate = New-SCServiceTemplate -ServiceTemplate $SvcTemplate -Name "ServiceTemplate02" -Release "RTM"
PS C:\> $WebTier = Get-SCComputerTierTemplate -ServiceTemplate $PendingTemplate -Name "Web Tier"
PS C:\> $WebTemplate = Get-SCVMTemplate -ComputerTierTemplate $WebTier | Set-SCVMTemplate -MemoryMB 2048
PS C:\> $BaseDisk2 = Get-SCVirtualHardDisk -Name "Win2k8R2BaseDisk_Patched.vhd"
PS C:\> $VHD = Get-SCVirtualDiskDrive -VMTemplate $WebTemplate 
PS C:\> Remove-SCVirtualDiskDrive -VirtualDiskDrive $VHD
PS C:\> New-SCVirtualDiskDrive -VirtualHardDisk $BaseDisk2 -VMTemplate $WebTemplate -BootVolume -SystemVolume -Bus 0 -LUN 0 -ide -VolumeType BootAndSystem
PS C:\> Set-SCService -Service $Service -PendingServiceTemplate $PendingTemplate 
PS C:\> Update-SCService -Service $Service

The first command gets the service object named Service02 and stores the object in the $Service variable.

The second command gets the service template object named ServiceTemplate02 and stores the object in the $SvcTemplate variable.

The third command creates a new release of the service template stored in $SvcTemplate, names it ServiceTemplate02, gives it a release of RTM and stores the template in $PendingTemplate.

The fourth command gets the computer tier object named Web Tier for the service template stored in $PendingTemplate and stores the object in the $WebTier variable.

The fifth command adds memory to the virtual machine template for the computer tier stored in $WebTier.

The sixth command gets the virtual hard disk object named Win2k8R2BaseDisk_Patched.vhd and stores the object in the $BaseDisk2 variable. This virtual hard disk contains an updated version of the operating system.

The seventh command gets the virtual disk drive object on the virtual machine template stored in $WebTemplate and stores the object in the $VHD variable.

The eighth command removes the virtual disk drive object stored in $VHD.

The ninth command adds the virtual hard disk object stored in $BaseDisk2 to the virtual machine template object stored in $WebTemplate.

The tenth command sets the pending template on the service instance to the updated service template stored in $PendingTemplate.

The last command updates Service02.
