Rebuilding a DPM server

If you determine rebuilding the DPM server is required, do the following:

1 Remove the backup host from VMM.

a In the VMM console, open the VMs and Services workspace.

b Under the All Hosts host group, remove the backup host on which the DPM VM resides.

2 Remove the corrupted DPM server from Operations Manager.

a Open the Operations Console.

b In the Administration workspace, expand Device Management > Agent Managed.

c Delete the agent on the corrupted DPM server.

3 On the Console VM, open Hyper-V Manager and connect to the backup host.

4 Delete the corrupted DPM VM.

5 Log on to the Console VM by using a local administrator account.

6 Update the manifest .XML le for redeployment.

a Update the backup host conguration. Search for the backup host name in the .xml le, locate the name of the backup host (for

example, S20B01) in the <BackupConfiguration> section of the le, and change the DeploymentStatus to

"DomainJoined".

For example:

<Nodes>

<Node Name="S20B01" DeploymentStatus="DomainJoined" ConfigurationID="828bc360-fd65-4304-

bc50-81ea4027ad7f" Password="" SerialNumber="22PGD42">

b Update the DPM node conguration. Search for <BackupVMs> in the le. For each DPM server, update DeploymentStatus

to "DomainJoined".

For example:

<Role Type="DPM" DeploymentStatus="DomainJoined" Name="S20DPM01" BackupHostName="S20B01"

ConfigurationID="02651dd9-3028-45a8-9188-9997aa816418" Password="">

</IPv4Addresses>

</Role>

<Role Type="DPM" DeploymentStatus="DomainJoined" Name="S20DPM02" BackupHostName="S20B01"

ConfigurationID="b7a1b6bd-23ff-4f4b-b68e-20ac5e19d005" Password="">

7 Set the password eld in the .xml le for the backup host.

a In a Windows PowerShell session, run the following script to set the $password variable to the password you want to set.

$password = "

YourPassword

ConvertTo-SecureString $password -AsPlainText -Force | ConvertFrom-SecureString

b Copy the output of this script.

c In the .XML le, search for the backup host name, and paste the output from the previous step between the quotes in the

Password="" eld.
