1 Volume Shadow Copy Service
Overview
The Volume Shadow Copy Service (VSS) provides a backup function that generates consistent
point-in-time copies of data known as snapshots.
VSS lets you conduct a hot backup of data without stopping online applications by linking
applications, backup software, and disk array systems that are supported by VSS.
VSS consists of the following components:
• Provider — The provider actually creates snapshots. The provider consists of a software
component that comes with the OS and a hardware component which may be acquired from
some source such as a disk array vender. The VSS provider described in this manual is the
hardware component.
• Writers — The writer quiesces the OS or an application and will flush data as needed in
order to create a consistent state. Only operating systems and applications that include a
VSS writer can work with VSS.
• Requester — This component requests creation, operation, or deletion of snapshots. Usually
backup and recovery software like Microsoft’s Data Protection Manager, or HPE Data
Protection Suite can operate as a VSS requester.
• VSS — This service in the Windows operating system operates as a coordinator for the
provider, the writers, and the requester.
Figure 1 Concept of VSS.png
Overview of the VSS Provider
The VSS Provider is a program that controls a data backup function and works with the Microsoft
Volume Shadow Copy Service (VSS). It uses Business Copy, Snapshot or Fast Snap in Hewlett
10 Volume Shadow Copy Service
Packard Enterprise disk array systems such as the XP P9500 and the XP7. This program delivers
backup integration operations with VSS. This program provides the following functions:
• VSS provider — HPE XP Storage Adapter for Microsoft® Volume ShadowCopy Service is
a fully-functional VSS implementation. The provider performs copy control of the Business
Copy or Snapshot pair in the disk array system targeted for a backup.
• GUI tools — With the GUI tools you can confirm and set up the configuration necessary for
the VSS Provider's operation.
Figure 2 Backup image
Overview of the VSS Provider 11
2 Environmental Prerequisites
System configuration
The system configuration requirements for VSS Provider are shown below.
• The HPE VSS Hardware provider must be installed on both the backup and recovery
application server (such as the media server in a Symantec NetBackup environment) and
the application server (such as a Microsoft Exchange server) from which a backup will be
taken.
• Table 1 (page 12) shows the connection of I/O path between servers and disk array systems
and the connection that VSS Provider gives an operation direction to the disk array systems
for FC environment support.
• In the case of XP P9500/XP7, the command device must be mapped on an application
server and a backup server.
• IPv6 is not supported.
• Fiber channel switches are not always required. Use them according to your environment
as needed.
• Multiple disk array systems can be connected to both an application server and a backup
server.
• For the application server, a cluster configuration using MSCS (MSFC) is also possible. (For
the backup server, this configuration is impossible.)
• The necessity of using the same operating system on both the backup server and the
application server depends on the backup software.
Table 1 Server and disk array systems connection
Examples of supported system configurations
VSS Provider supports the following system configurations.
Figure 3 (page 13) shows a similar configuration using a XP P9500/XP7 disk array system.

Example of VMware Guest to Guest Backup (FC) function system configuration
VMware Guest to Guest Backup (FC) function is that VSS Provider backups P-VOL connected
to ESXi with FC and VM on ESXi is used as an import server of replicated secondary VOL.
In case of using the VMware Guest to Guest Backup (FC) function, the following system
configurations are supported.
Nontransportable configuration
This is the configuration to backup in the Nontransportable configuration in which the secondary
VOL is imported to the virtual machine to be used as the application server.

Figure 4 Example of VMware Guest to Guest Backup (FC) function system configuration
(Nontransportable configuration)
Transportable configuration (one ESXi)
This is the configuration in which the virtual machines for the application server and backup
server uses are located on the same ESXi.

Server Account Authentication
In case of using VSS provider as the general user, server information and disk array system
information cannot be retrieved. Administrative right should be given to the server account.
Also, in case of Windows Server 2008 or later and use VSS Provider with the Windows logon
account having the Administrator rights other than the built-in Administrator, server information
and disk array system information cannot be retrieved.
VSS Provider can be used by disabling UAC though, using VSS Provider with the Windows logon
account having the Administrator right is recommended.
Environmental configuration via remote desktop
Configuration via a remote desktop is supported.
Installation, repair installation, uninstallation and update installation are possible.
26 Environmental Prerequisites
Items to confirm during installation
• Disable antivirus processes and other monitoring process services (daemon processes). If
such services (daemon processes) are active, installation may not be possible.
• When using firewall software other than the Windows firewall, disable or remove the software
during installation. In addition, allow settings for communication with TCP port 2000 after
installation.
• Other software must not use TCP port 2000.
Installation drive
Install only on local drives.
Installation on network drives and removable disks is not supported.
Path length of the installation folder
Installation folder of VSS Provider can be specified at the time of installation. Note that the path
length of the VSS Provider installation folder must be less than or equal to 200 bytes
Number of LUs which can be mapped to the host group
Up to 255 LUs per host group are recognizable by Windows (For details, visit
http://support.microsoft.com/kb/310072/en-us ).
Since WWN of the backup server maps S-VOL for a backup to the registered host group, if the
host LUN number is 255 or more, S-VOL cannot be recognized due to Windows specification
mentioned above and backup processing fails.
In addition, the following error is output in the event log. <Event ID 12362>
How to create setup, maintenance configuration, and configuration files
Use the configuration files which are automatically created during VSS HW provider installation.
Files that are made by other means (by text editor or the like) may be overwritten during
installation, repair installation or update installation.
If you delete a file by mistake, restore the file by VSS HW provider repair installation and
reconfigure the necessary information as explained in “User edit files” (page 37).
Hewlett Packard Enterprise shortcut of the Start Menu
When installation/uninstallation is performed by multiple Windows accounts on the equivalent
server, "Hewlett Packard Enterprise" shortcut may be left for the Start Menu of Windows at the
time of uninstallation. You may ignore it, but you can delete it.
To delete the shortcut:
1. Log off in the account except the Windows account that uninstalled VSS Provider.
2. Confirm whether there is Hewlett Packard Enterprise folder for the Start Menu of each
following Windows accounts and delete it if it exists.
<system drive>:\Users\<Windows
account>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
3. Confirm whether there is Hewlett Packard Enterprise folder for the Start Menu of the ALL
user and delete it if it exists.

Software account addition window.
For the characters and can be used for user name and password as well as the number of
characters can be entered, refer to the RAID Manager command reference.
RAID Manager (HORCM)
• Start RAID Manager (HORCM) prior to starting any RAID Manager commands from VSS
Provider.
See “Preparing configuration files and restarting RAID Manager (HORCM)” (page 43) for
details.
• In the case of the Ext Stor configuration or HA configuration, do not describe HORCM_VCMD
in the HORCM CONF configuration file.
• Do not use the HORCM CONF configuration file used by VSS Provider except for the purpose
of VSS Provider.
Host group creation
Host groups must be created in disk array systems, see Table 7 (page 46).
Creating a user authentication account for storage administration
The disk array system must have the same user name and password when using multiple disk
array systems of the XP P9500/XP7.
For example:
When using disk array system A or B, the same user name (USER01) and password (*****) must
be used.
• Storage A:
User name — USER01◦
◦ Password — *****
• Storage B:
User name — USER01◦
◦ Password — *****
28 Environmental Prerequisites
Assigning LDEV ID
• When configuring Ext Stor, to create secondary VOL (S-VOL/V-VOL) using VSS provider
and GUI, assign the physical LDEV ID to RSG which P-VOL belongs to, in advance.
• Assign virtual LDEV ID to physical LDEV ID as well.
(Do not operate the physical LDEV ID to which the virtual LDEV ID has not been set (Virtual
LDEV ID will be FF:FE) or the physical LDEV ID reserved for HA (Virtual LDEV ID will be
FF:FF))
• In the case of using virtual DKC which straddles multiple physical DKCs, make sure that
virtual LDEV ID is not duplicated in virtual DKC.
Resource Group (Resource Partition)
Do not create Resource Group other than meta_resource in the storage system because Resource
Group is not supported.
Exceptionally, this restriction can be relaxed under H-UVM configuration. See “Support scope
of Ext Stor configuration ” (page 22).
Raw Device Mapping (RDM)
LU which is used as P-VOL must be mapped on the application server in RDM (physical
compatibility mode).
Command device
In case of using XP P9500/XP7 disk array systems, command device must be mapped on the
application server/backup server in RDM (physical compatibility mode)
SCSI controller type
SCSI controller type of the virtual machine supports LSI Logic SAS.
SCSI controller created by VSS Provider
If RDM required sufficient free virtual device node is not available on the import destination virtual
machine during the secondary VOL import process, VSS Provider creates SCSI controller using
the following settings.
• SCSI controller number — Use from not created and smaller controller number
• SCSI controller type — LSI Logic SAS
• Sharing SCSI path — Nil
VMware HA
To use VMware HA, the following conditions must be fulfilled:
• WWN used for the failover of the node participating in VMware HA, write in the configuration
file using the “WWN of ESXi” specified option.
• Register the above WWN in HG which is used for VSS Provider.
• Confirm that the failover operates by using the corresponding HG in advance.

Unregistering a disk array system
To unregister a disk array system registered by the Add Storage function of the GUI tool, remove
the IP address and the serial number from the setup file.
Number of user accounts that can be registered for a disk array system
Use the Add Storage function of the GUI tool to register user accounts.
Only one account can be registered for a disk array system.
To change a user account, you must re-register the disk array system using the Add Storage
function and specify a new user name and a password.
Changing the configuration file or the maintenance configuration file
The VSS HW provider GUI will need to be restarted when a change to the configuration file or
the maintenance configuration file are made while they are in use.
Restarting a server during a backup
When the server reboots during a backup, depending on the backup software and the timing of
a server reboot, the pair state will be PSUS or PAIR after resynchronization is completed.
When a pair status is suspended, perform the confirmation and recover steps outlined in
“Confirmation and support after a recovery” (page 135).
Log collection during problem occurrence
Because a log may wrap, collect a log and save it during the problem occurrence.
See “Information collected during problem occurrence” (page 137) for the log to collect.
