HP StorageWorks EVA VDS and VSS Hardware Providers 6.04.00 for Windows Server 2008 R2 release notes (T1634-96087, November 2009)

NOTE:
Windows Server 2008 R2 Server Core and Windows Hyper-V Server 2008 R2 run only on x64
servers.
For installation instructions see the HP StorageWorks Hardware Providers for VDS/VSS installation
guide (T1634-96088, October 2009). The guide is included with the installation software package
and provides detailed installation and configuration instructions.
Compatibility/Interoperability
• Only one dedicated Command View workstation is supported within the SAN configuration which
manages VDS/VSS storage resources.
• If the EVA VSS hardware provider and Command View EVA are present on the same server, do
not include the drive letter or mount point where the Command View EVA software is located as
part of a shadow copy volume set. For example, if the EVA VSS hardware provider and Command
View EVA are on drive D, do not include drive D with an EVA LUN in a shadow copy set. Doing
so causes the EVA VSS hardware provider to time out due to conflict with Command View logging
on this drive.
• Mirrorclones are supported with microcode version XCS 6.11 or later.
• Version 6.04.00 of the HP StorageWorks Enterprise Virtual Array Hardware Providers software
is the last version that will support the HP StorageWorks 3000 EVA Storage System and the HP
StorageWorks 5000 EVA Storage System.
• The hardware providers do not support vdisks created under a folder that is nested within 40 or
more recursively nested folders.
• A LUN resync operation occurs when a source LUN is restored from a shadow copy created by
using one of the following techniques: Snapclone, mirrorclone, snapshot, or mirrorclone-snapshot.
In a LUN resync operation, the source LUN is the LUN used for creating a shadow copy, and a
different LUN is a LUN that is not the source LUN of the shadow copy used for resync/restore.
LUN resync is supported on all EVA arrays except for the HP StorageWorks 3000 EVA Storage
System and the HP StorageWorks 5000 EVA Storage System.
The following resync scenarios are supported:
• Resync from a demand-allocated or fully-allocated snapshot to the source LUN
• Resync from a fractured mirrorclone to the source LUN
• Resync from a demand-allocated or fully-allocated snapshot of a mirrorclone to the mirrorclone
source LUN
• Resync from a snapclone to the source LUN
• Resync from a snapclone to a different LUN
The following resync scenarios are not supported:
• Resync from a snapshot to a different LUN
• Resync from a fractured mirrorclone to a different LUN
• Resync from a snapshot of a mirrorclone to a different LUN
• Creating a snapshot immediately after a LUN resync operation will fail if you do not restart the
VSS service after the resync operation. To restart the VSS service, run the commands Net stop
VSS and Net start VSS or select the Restart option for the VSS service listed in the service
control manager snap-in.
