set will be created with the same time stamp and will present the same disk state for a multivolume
disk state.
• Native shadow copy support. Beginning with Windows XP, shadow copy support is available
through VSS as a native part of the Windows operating system. As long as at least one NTFS disk
is present on a system, these systems can be configured to support shadow copies of all disk systems
mounted on them.
Installing and configuring Microsoft VSS with VSM virtual disks
Use the following checklist to make sure that you implement all of the requirements for running VSS
on the VSM virtual disks presented by the DPMs. The checklist applies to each host that is using VSS.
These hosts include the application hosts and the hosts that back up the data to tapes or disks.
Configuration checklist for VSM deployment with VSS
• You are using an actual Windows server, not a Windows virtual machine on a VMware ESX
server, and the full-featured DSM has been installed.
• Confirm that the server is defined as a host in the VSM GUI.
• On the VSM, create the SAN CLI virtual disk and present it to the host.
• On the host, make sure that the SAN CLI virtual disk is recognized on Disk Management.
• On the host, install the SVSP VSS hardware provider. See “Installing the SVSP VSS hardware
provider on the host server” on page 82.
• On the host, configure the SVSP VSS hardware provider with a user that can access and manage
the SVSP domains.
• On the host, install the Microsoft hot fix KB891957, which fixes volume Shadow Copy Service
issues in Windows Server 2003. You can download KB891957 from http://support.microsoft.com/
kb/891957.
Installing the SVSP VSS hardware provider on the host server
NOTE:
For VSS to work correctly, you must first install the SVSP full-featured DSM.
You can install the SVSP VSS hardware provider using a single installation package. The final step
in the installation process automatically starts the SVSP VSS Hardware Provider Service.
