Data Protector Agent Windows 2008 – Cannot connect to the SCM

When installing the Data Protector Agent to a Windows 2008 R2 Server the following errormessage appeared:

[Critical]  Cannot connect to the SCM (Service Control Manager) on client <clientname>
[5] Access is denied.

What we need to do now is to add a User with admin rights to the INET Service. Open a command prompt and enter these commands:

C:\Program Files\OmniBack\bin>omniinetpasswd.exe -list

This will show you if there are any users configured already

Now add a user to the INET Service. This user should have administrative permissions and – of course – this user should already be created in your AD.

C:\Program Files\OmniBack\bin>omniinetpasswd.exe -add <domain>\dataprotector
Please enter password:**********
Please retype password:**********
User '<domain>\dataprotector' was successfully added.

Last step is to add this useraccount to be used by the installation service:

omniinetpasswd.exe -inst_srv_user <domain>\dataprotector
User '<domain>\dataprotector' is configured to be used by Installation Server.

Using Raw Device Mapping (RDM) with SAS attached storage

The ESX-Server does not “know” that the attached SAS-Storage is a shared storage (like HP MSA 2xxx) so it will not allow us to create a RDM disk file within a VM. To do this we need the CLI.

Assuming the volume is already mapped to the ESX-host and can be seen by the ESX-Host we need to do the following:

  1. Connect to the host using a SSH session
  2. Display the paths using “esxcfg-mpath -m” and look for the volume – if we know the LUN we can do a grep (e.g. “esxcfg-mpath -m |grep -i l10”  – this would only display the volume with the LUN-ID 10)
  3. Copy the naa-ID (naa.12345lotofnumbers7890)
  4. To create a RDM enter: “vmkfstools -z /vmfs/devices/disks/<your naa-id here> /vmfs/volumes/<your vmfs-volume here>/<your vm-name here>/<diskname here>.vmdk”
  5. Please note that the parameter “-z” creates a physical RDM – if you want to use a virtual RDM use the parameter “-r”
  6. Go to your VM and add a Disk
  7. Select “Existing disk” and browse to the diskfile you created in step 4
  8. Finish and do a rescan of disks in your VM

Cannot install vCenter converter – Error 29454

This error occured when I tried to install vCenter Converter on a vCenter Server 4.1 (Build 259021)

To resolve this error check the vpxd.log located in
%allusersprofile%\VMware\VMware VirtualCenter\Logs
and search for “failed to add LDAP entry”.
Copy the CN Name you find there.

In my case this was


Now open up ADSI-Edit an connect to the localhost (Port 389) chose “Connection Point” and enter


Click OK

Expand “OU=Health” and rightclick “OU=ComponentSpecs” – select “New”-> “Object”. Select “container” and OK.
Enter the CN-Name you copied before.
Should look like this afterwards:

Now run the installation again.
