Detailed Description

The Repair-SCVirtualMachine cmdlet repairs a virtual machine in a failed state that is on a host managed by System Center Virtual Machine Manager (VMM). A virtual machine can be in one of four types of failed state:

- Creation Failed

- Migration Failed

- Update Failed

- Deletion Failed

You can use this command to repair a failure as follows:

* RETRY. Attempts to perform the failed job again.

* UNDO. Attempts to undo any changes made to the

virtual machine and restore it to a healthy state. For

example, if a Move-SCVirtualMachine job fails, using

the Undo option attempts to move the virtual machine

back to its previous host.

* DISMISS. Dismisses the failed job and refreshes the

virtual machine based on its current state. If you manually

fix a failure (for example, by manually moving the .vhd and

.vmc files to a new host after a failed Move-SCVirtialMachine

attempt), you can use the Dismiss option to refresh the data

for the virtual machine in the VMM database. However, using

the Dismiss option might return the object to the failed state.

When you run Repair-SCVirtualMachine, you can specify only one type of action at a time.

You can run Repair-SCVirtualMachine to repair an in-guest agent for a virtual machine that is part of a service by using the Agent parameter.

-Credential<VMMCredential>

Specifies a credential object or, for some cmdlets, a Run As account object that contains the user name and password of an account that has permission to perform this action. Or, in the case of Restart-SCJob, has permission to complete a restarted task.

For more information about the PSCredential object, type: "Get-Help Get-Credential".

-Dismiss

Dismisses the error on an object or an update notification on a service instance.

After an error is dismissed, the object is refreshed. If the error reappears, refreshing does not solve the problem and you must fix the error.

For example:

- Remove-SCSCVMHost -Force

Forces the removal of a host object from the VMM database.

- Stop-SCVirtualMachine -Force

Stops a virtual machine.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

  • VirtualMachine

Notes

  • Requires a virtual machine object, which can be retrieved by using the Get-SCVirtual Machine cmdlet.

Examples

1: Repair a failed migration task by retrying the migration task.

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable. This example assumes that the task that you want to repair by using the Retry parameter is an attempt to move (migrate) the virtual machine from one host to another.

The second command repairs the virtual machine object stored in $VM (in this case, VM01) by restarting the previous failed migration task.


PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"PS C:\> Repair-SCVirtualMachine -VM $VM -Retry

2: Repair or upgrade the VMM In-guest agent on a specified virtual machine that is part of a service.

The first command gets the virtual machine object named ServiceVM01 and stores the object in the $VM variable. This example assumes that the virtual machine is part of a service.

The second command gets a credential object, which must be a local administrator on the virtual machine to be repaired and stores the object in the $Creds variable

The third command repairs the in-guest agent on the virtual machine object stored in $VM (ServiceVM01).


PS C:\> $VM = Get-SCVirtualMachine -Name "ServiceVM01"PS C:\> $Creds = Get-CredentialPS C:\> Repair-SCVirtualMachine -VM $VM -Credential $Creds -Agent
