[<CommonParameters>]Description
The Update-SCService cmdlet updates an instance of a 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 not allow 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.
Examples
Example 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 $ServiceThe 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.
Example 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 $ServiceThe 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.
Parameters
-JobVariable
Specifies that job progress is tracked and stored in the variable named by this parameter.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-OnBehalfOfUser
Specifies a user name. This cmdlet operates on behalf of the user that this parameter specifies.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-OnBehalfOfUserRole
Specifies a user role. To obtain a user role, use the Get-SCUserRole cmdlet. This cmdlet operates on behalf of the user role that this parameter specifies.

| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-PROTipID
Specifies the ID of the Performance and Resource Optimization tip (PRO tip) that triggered this action. This parameter lets you audit PRO tips.

| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-RunAsynchronously
Indicates that the job runs asynchronously so that control returns to the command shell immediately.
| Type: | SwitchParameter |

| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-ShowActions
Displays all servicing and orchestration actions that will be performed. This parameter is useful for debugging.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-VMMServer
Specifies a VMM server object.
| Type: | ServerConnection |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.

| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
Outputs
Service
This cmdlet returns a Service object.
Notes
- Requires a VMM service object, which can be retrieved using the Get-SCService cmdlet.
