VDS/VSS HP hardware providers will not install
The HP hardware providers installation works only on the Windows versions mentioned in this guide
and in the release notes supplied with the HP hardware providers. The installer will not install the
software on other versions of Windows.
For EVA only: The VSS hardware provider may not install if the system Microsoft Distributed Transaction
Coordinator (MSDTC) service fails to start. When this occurs, the following message is displayed:
The registration of the hardware provider did not complete successfully.
For additional information on minimum system requirement please refer to
the administration guide.
Make sure that the MSDTC service is running. If it is stopped, the VDS/VSS installation will fail.
VDS disk array management not working
Use a process of elimination to determine whether the problem is with one of the following components:
• Application managing the array
• VDS
• HP hardware providers
• HP disk array
Perform the following test and verification steps to troubleshoot the problem:
1. Do the array volumes appear in the Disk Management tool? To check, in the Windows menu
bar select Start > Control Panel. Select Administrative Tools. Under Computer Management, select
Disk Management (under Storage). If array LUNs are not visible, click Action > Refresh and Action
> Scan Disks.
