About this guide
This guide provides information about configuring and using HP
StorageWorks EVA Fast Recovery Solutions (FRS) in a Microsoft
Windows Server 2003 environment running Exchange 2003. FRS enables
quick recovery of Exchange storage groups.
FRS combines LUN copy creation and database recovery features for use
with HP StorageWorks EVA disk arrays. Using the Microsoft VSS
(Volume Shadow Copy Service), FRS creates and manages recovery-ready
copies of the production Exchange 2003 storage groups to be used in the
event of a disaster. FRS allows you to recover storage groups in minutes
rather than the hours typically required for a conventional restore from
backup.
Unless otherwise noted, the term disk array refers to the disk arrays listed
on the front cover of this guide.
Related information
For information about the disk arrays, please refer to the owner’s manuals.
IMPORTANT: firmware and software dependencies
This guide describes FRS behavior based on features implemented in the
latest disk array firmware and software versions. FRS may not work if
incompatible software versions are used. Check the Readme file to verify
that you have the correct versions.

FRS overview
FRS is a Windows server tool designed to enable fast recovery when an
Exchange storage group maintained on an HP disk array becomes
damaged.
(1) Use Production Server to store
production data on array primary
volume.
Store

(2) Use FRS GUI on Recovery Server
to copy production data to secondary
array volume.

(3) In the event of production data damage,
restore primary data from the seconda ry data
using the FRS GUI on t he Recovery Server.
Restore
Recovery Data (read-only) is routinely available on
the secondary disk for data mining or transport.
The FRS life cycle can be summarized as follows:
• (1) The production server maintains production storage groups or
databases on specified production volumes of the disk array.
• (2) The FRS GUI runs on the recovery server. It captures copies of the
Exchange storage groups from the production volumes and stores
them on recovery volumes of the array. FRS creates, maintains, and
manages these “recovery-ready” copies.
• (3) When a data corruption occurs, the administrator uses the FRS
graphical user interface to replace the damaged storage group or
database with the most recent known good recovery-ready copy.
Overview17
Additional FRS capabilities
FRS can create and maintain copies of storage groups or databases for
multiple production servers. The FRS user interface allows Exchange
instances to be added or deleted from FRS management at will.
FRS supports Microsoft clustering. Without compromising the cluster or
taking it offline, FRS provides quick database recovery.
Database integrity checking is included in FRS. FRS interacts with the
Microsoft Exchange eseutil integrity checking tool for Exchange to check
database copies and recovered databases, ensuring they are free of logical
and physical corruption.
FRS performs both point-in-time and roll-forward recovery.
Functional components
The process of creating and managing recovery copies on the disk array
using FRS involves the following components:
• Exchange
• HP FRS
• Windows VSS Service
• HP VSS Hardware Provider

Overview19
Exchange
FRS
Exchange runs on the Producton Server and writes data to primary disk
array volumes. FRS protects Exchange by creating and managing shadow
copies of Exchange storage groups.
Software components called “writers” interface with Exchange to
coordinate volume shadow copy creation. Some operating system writers
come with Windows, while others, such as the Exchange writer, come with
the application software.
Upon request from FRS for a shadow copy, the writer flushes the
application buffers and holds I/O to the application. It then notifies the VSS
hardware provider that it is ready for a shadow copy, and the VSS HWP
copies the production volume to a recovery volume. When the copy is
complete, VSS releases the application to resume normal operation. This
process ensures consistent data even though the application is still running.
FRS consists of two sets of components: one set of production server
components, and a separate set of recovery server components, including a
graphical user interface. FRS as a whole is referred to by Microsoft as a
“requestor” application that requests service from VSS.
The FRS GUI runs on the recovery server and provides user control of FRS
on the production server. You can use the FRS GUI to make shadow copies
of the data on the production LUNs, and use the GUI to recover the
complete dataset from a copy on the recovery LUNs.
FRS on the production server interacts with the Windows VSS service and
HP Hardware Provider (HWP). When FRS requests it, this service and
provider combination coordinates with the writer and application to create a
volume shadow copy of the production data on the production array LUNs.
The complete recovery-ready copy is placed on recovery array volumes.
FRS presents the recovery volumes to the recovery server through VSS.
This enables you to use the recovery server to archive the recovery data to
backup tapes at any time. In the event of production data corruption, you
20HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
can use the FRS GUI to restore the production volumes from the most
recent data copy or another point-in-time copy on the recovery volumes.
Volume Shadow Copy Service (VSS)
Microsoft’s VSS manages creation and maintenance of shadow copies of
production data for backup and recovery. This service works under the
control of the FRS interface and the Windows OS file system services.
When requested by FRS, VSS coordinates with the writer and hardware
providers to perform shadow copying of production data to the recovery
volumes. The shadow copies contain static copies of all files, such as
databases, transaction logs, and checkpoint files.
Copy terminology
Understanding how Microsoft VSS terminology corresponds to standard IT
industry terms for data copying makes it easier to understand what VSS
does. The following paragraphs explain the terminology.
Microsoft generally refers to a VSS copy as a “volume shadow copy.”
When created using HP FRS and HWP, this type of copy is a static replica
of an original volume’s contents. It is keyed with a GUID to allow
identification of the parts of a shadow copy set that span multiple volumes.
Microsoft also refers to a VSS copy as a “plex,” commonly known in the IT
industry as a “split mirror.”
When you use an EVA array to make the shadow copy, the array makes
what is known as a “snapclone.” An EVA Snapclone is a complete clone
copy of a specified Virtual Disk (LUN). EVA snapclones are available
almost immediately. This is accomplished by creating a point-in-time copy
and making it immediately available by pointing to data on the original
volume while continuing to copy data to a secondary volume in the
background. When copying is complete, the snapclone is a static
point-in-time copy of the original.
The shadow copies made on the EVA array using VSS, FRS, and HWP are
always static, point-in-time copies.
Overview21
VSS process flow
The following steps show the VSS process flow:
1. A Requestor application (FRS) initiates a Volume Shadow Copy.
2. FRS requests that the Volume Shadow Copy service create a shadow
copy of a selected set of storage groups.
3. VSS tells the Writer and application to prepare for a shadow copy. The
Writer reports which LUNs to copy, flushes cache, and holds I/O.
4. VSS tells the disk array through HP HWP to create a shadow copy of
the production storage volume.
5. VSS releases the writer application to resume normal operations.
6. The Requestor (FRS) presents the recovery LUNs to the recovery server
using VSS, waits for normalization, runs integrity checking, verifies
backup integrity, truncates logs upon success, and tells the writer that
the backup was successful.

Disk Array
HP VDS/VSS Hardware Providers
Windows Server 2003 sees, partitions, mounts, and manages file systems
on the disk array using its own software providers. HP’s Hardware
Providers extend the array management capabilities of Windows and its
applications to include functions normally performed using the disk array’s
proprietary control software. These functions include managing disk array
LUNs and ports and performing volume copy operations.
HP’s Business Copy (BC) application, which resides on the disk array and
is licensed in Command View, works with the VSS and the HP HWP
components to enable the array to make VSS shadow copies. For functional
purposes, you can think of BC as a part of the hardware providers, even
though it is installed separately.
For more information about the HP Hardware Providers, refer to the HP
EVA Hardware Providers Administration Guide.
HP disk arrays
The HP EVA array works with FRS, Microsoft VSS, and HP VSS HWP to
perform snapclone creation, storage, and management. FRS takes
advantage of the many advanced capabilities of the EVA disk array to
provide multiple recovery options.

FRS only from one management console to prevent simultaneous
commands to FRS from different sources.
• FRS supports only a homogeneous disk array solution. If you want to
run FRS on an XP1024 and an EVA6000 disk array, for example, you
will need two mutually exclusive recovery servers—one per disk array
with no shared components.
• FRS supports multiple arrays of the same model, but all arrays must

Important general configuration notes
The following notes will help ensure a successful configuration:
• Production and recovery servers must be in the same Ethernet domain
so that the DCOM communication process works between servers.
• Administrator privileges are required for all devices and software. If
you do not have administrator privileges, the software and hardware
will not communicate properly.
Configuration29
Important performance issues
Take steps to prevent these issues which can affect FRS performance:
• Excessive traffic on the Ethernet LAN.
• Viruses that slow down network traffic.
• A firewall that slows traffic between the servers hosting FRS and the
CV server. Any firewall must be open between these systems.
Important Exchange 2003 configuration notes
FRS works within the limits of Exchange 2003. No more than five
databases per storage group and no more than four storage groups per
Exchange instance are supported.
FRS manages Exchange 2003 at the storage group level. The following
configuration rules apply:
• All databases within a storage group must reside on one LUN of the
HP disk array. Databases cannot be separated onto different storage
LUNs.
• The logs for each storage group must also reside on an HP disk array
LUN, and the logs and the checkpoint file must remain together on the
same LUN.
• The LUN that the databases reside on and the LUN that the logs reside
on must NOT be the same LUN.
FRS requires that a copy of the MS Exchange eseutil.exe and ese.dll
utilities be placed in the installation directory (c:\hpfrs) on the recovery
server.

Installing FRS on recovery and production servers
FRS is required on all servers participating in FRS. This includes the
recovery server and all production servers. For example, if one FRS
recovery server will host two Exchange 2003 servers, you must install FRS
on all three servers.
The installation steps for each production or recovery server are nearly
identical, except for the Custom Setup window:
1. Download FRS from the hp.com web site or open the FRS CD and
launch the ISScript8.Msi file. This will ensure that a script engine is
available for the installation process.
2. Click Next and read the license agreement.
3. Click “I accept” and click Next.
4. Click Install to install ISScript on the server.
5. When ISScript installation completes, click Finish.
Installation41
6. Launch the HP StorageWorks Fast Recovery Solution.msi file. The
installation wizard opens.
7. Click Next. The Custom Setup window opens.
8. Choose Change... to select a directory where the program will be
installed, or use the default location shown under Install to:.
9. Select the type of server software you want to install:
To install on a PRODUCTION server: Click the Production
Server drop down menu, and select “This feature will be installed on
local hard drive”. Then click the Recovery Server drop down menu
and select “This feature will not be available.” The recovery server
icon is marked with an “X”, which means it is NOT being installed.
To install on a RECOVERY server: Click the Recovery Server
drop down menu, and select “This feature will be installed on local hard drive”. Then click the Production Server drop down menu and
select “This feature will not be available.” The production server
icon is marked with an “X”, which means it is NOT being installed.
42HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
10. Click Next.
11. Click Install. Installation begins.
12. When installation completes, click Finish.
13. Repeat the installation on all additional servers participating in FRS. Be
sure to select the correct server icon each time and to deselect the
unwanted icon so that it is marked with an “X”.
Installing integrity checking components
For Exchange integrity checking to work, you must copy the Exchange
eseutil.exe and ese.dll files to the c:\hpfrs directory on the recovery server.
These files are located in the Exchange directory: c:\program files\exchsrvr\bin. If these files are not present in the FRS directory on the
recovery server, copying will fail.
Installation43
Enabling the FRS license using AutoPass
FRS offers a free trial license period of 60 days. When the trial period is
over, you must install a permanent license using AutoPass within the FRS
GUI in order to continue using FRS. The procedure for starting the
permanent licensing process is different depending on whether your trial
license has already expired or not. Use one of the two procedures below to
install the permanent license.
Installing a permanent license before trial expiration
If you are installing a permanent license before the trial license expires, a
command line application called ImportLicense.exe allows you to install
the license:
1. Locate and double click the ImportLicense.exe executable file to run
it. The path to this file is Start>Programs>Hewlett-Packard>HP StorageWorks Fast Recovery Solution>Import Permanent License.
The AutoPass: Import Passwords screen displays.
2. Follow the procedure for “Permanent license installation” on page 45.
Installing a permanent license after trial expiration
When you start the FRS GUI, a window notifies you how many days
remain before your trial version of the software expires.
If your AutoPass trial version license has expired, this message appears:
1. Click Ye s to install the license (or click No to exit FRS).
2. Follow the procedure for “Permanent license installation” on page 45.
44HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Permanent license installation
Important: If you have multiple FRS instances, be ready to import all
license passwords for all instances in one session. If you quit AutoPass
while some licenses are still without passwords, all licenses will fail, and
AutoPass will have been overwritten and disabled by the partial license file.
Use the following procedure to install the permanent license(s):
1. When you click Ye s on one of the preceding license notification
windows, the AutoPass: Import passwords window opens.
2. Click the Browse button to locate the license password file. The file
path shows in the file path text entry box.
3. Click the View file contents button to display the license passwords
stored in the file.
Installation45
4. Click the password file in the display to highlight it (as shown above).
5. Click Import to import the selected password file.
The message below indicates a successful password import.
46HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Instance count check
If you are running too many instances of FRS for the license you own, you
may receive a warning message. This message appears under the following
conditions:
6. Click OK. This completes installation of the license password.
Important: If you need to install multiple licenses, you must repeat
this process for each license password. It is not possible to import
multiple passwords at one time.
Also, be sure you have imported all licenses before closing AutoPass.
If some licenses are left without passwords, all licenses will fail.
• The recovery server is connected to a production server running more
than the licensed number of instances.
• A recovery server is connected to multiple production servers and the
total number of Exchange instances running are more than the licensed
capacity.
• The product is already running the maximum number of instances
when you try to add another instance by clicking Add Exchange Server Instance from the File menu.
Contact HP if you need to add more instances to your license.
Installation47
Recovery server XML files
FRS stores the recovery volume information in the form of XML files. By
default these files are created in the install directory. It is not necessary to
change the location of the XML files, but should you wish to do so, you can
place these files in a different directory.
Important: If you change the location of the XML files after snapclones
have already been created, the FRS GUI will not be able to find them, so
HP recommends changing the location before you create any snapclones.
The following procedure explains how to change the location of this
directory:
1. Start FRS on the recovery server by clicking
Sta rt>Programs>Hewlett-Packard>HP StorageWorks Fast
Recovery Solution>FRS GUI.
2. Click the ShadowCopy menu and click Options.
The Options window containing the default location appears.
3. Click Browse, browse to a directory of your choice, and click OK.
4. Click OK in the Options window to change the default XML file path.

Using FRS
Opening FRS
You operate FRS from the graphical user interface that was installed on the
recovery server when you installed FRS. The following pages explain how
to open and use the FRS GUI to add and delete servers, make shadow
copies of production storage groups and restore production storage groups
and databases from shadow copies.
1. On the recovery server, click Windows Start, and select Programs.
2. Click Hewlett-Packard, click HP StorageWorks Fast Recovery Solution, and click HP FRS GUI.
The FRS main window opens.
52HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Using the main window
The following example shows the FRS main window after two Exchange
2003 server instances have been added. Adding server instances is
explained later in this chapter.
Using FRS53
To expand a server instance:
1. Click the plus symbol (+) next to a server instance in the left panel of
the main window. This displays the detail views of the production
storage groups and/or databases associated with that server instance.
2. Click a storage group or database to display the location and path of the
LUN where it is stored in the right panel of the main window.
54HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Adding server instances
Add Exchange production server instances whose storage groups or
databases you want FRS to be able to copy and restore. The servers must
have FRS installed on them for the GUI to recognize them:
1. On the FRS main window, click the File pulldown menu and click
2. Enter the instance name in the “Enter Server Instance” box and click OK.
Add Exchange Server Instance.
The Add Server Instance window opens.
The FRS main window opens and shows the new server instance.
Using FRS55
Deleting server instances
If you no longer need to use FRS with a particular server, you can delete it
from the FRS GUI. This does not affect the server itself but only removes it
from the list of servers available in the FRS main window.
1. Click the server instance to highlight it.
2. Click File and click Delete Server Instance. A confirmation window
opens.
3. Click Ye s to confirm your choice.
56HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Creating shadow copies
The primary feature of FRS is creating shadow copies of production LUNs.
FRS then manages these copies. If a production database is lost because of
a failure or catastrophic event, FRS restores the production database from a
shadow copy.
To create shadow copies of production LUNs:
1. Click the production server instance, storage group, or database you
want to copy. The example below shows Exchange 2003 Server “N03”
selected.
2. Click ShadowCopy in the menu bar, and select Create Shadow Copy.
The Create shadow copy window opens.
Using FRS57
3. Select the storage group to be copied and click Add. Repeat as needed.
The storage group to be copied appears in the “Selected for shadow
copy” list, and the associated databases appear in the “Files/Volumes
selected for shadow copy” list.
58HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
4. Click Create at the bottom of the Create shadow copy window. Storage
group copying begins. The copy is placed on a volume in the recovery
storage group you identified when you installed FRS.
The Activity Log shows the stages of copying and their success or
failure, ending with a completion message.
5. When copying ends, click Close to close the window. FRS now has a
recovery-ready LUN containing the shadow copy of the storage group
or database. You can create shadow copies as often as needed.
Troubleshooting copy failures:
If a copy fails, you may be able to troubleshoot the cause by examining the
copy activities shown in the Activity Log to see which activities failed.
Failed Exchange copies can often traced to a failed integrity check
performed automatically on the storage group by the Microsoft Exchange
eseutil.exe utility. Integrity check failure typically indicates physical file or
page damage in the production storage group.
Using FRS59
Executing an FRS recovery
Use the Recovery feature to restore a production storage group from an
FRS shadow copy.
1. Click Recovery on the main window menu bar, and select
Roll-Forward Recovery or Point-in-Time Recovery.
Roll Forward Recovery
Use Roll Forward Recovery if the production storage group's
database(s) becomes damaged but the storage group's transaction logs
are known to be unaffected. This recovery method replaces the
production storage group's database LUN with the latest known-good
shadow copy but does not replace the production transaction log LUN.
During the recovery, Exchange replays the production logs to fully
restore the production databases up to the last logged transaction prior
to the point of failure. A Roll Forward Recovery only works with the
most recent Point-in-Time shadow copy.
Point-in-Time Recovery
Use Point-in-Time recovery if the production storage group's
transaction logs are damaged. This recovery method replaces the
production storage group and production logs with the point-in-time
copy that you select. A Point-in-Time recovery will cause you to lose
60HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
all data created after the Copy Date and Copy Time of the selected
shadow copy.
After you select a recovery method, the Recover Storage Group
window opens and indicates the type of recovery in the window name.
The copies available for selection differ in this window depending on
whether you selected Roll Forward or Point-in-Time.
Using FRS61
2. Click on the production storage group you want to recover in the Select
Storage Group panel.
A list of point-in-time shadow copies displays in the Point-in-Time
copies panel. The contents of the list depends on whether you selected
Roll Forward or Point-in-Time.
3. Click the point-in-time copy you want to use to restore the production
storage group.
Note: The point-in-time recovery dialog shows only the point-in-time
copies residing in the user specified xml file path. If you want to see
the point-in-time copies in other directories you must change the xml
file path to point to those directories.
4. Select LUN Swap or Full Resync. (These are grayed out for PIT.)
Full Resync replaces the production data on the production LUN with
the most recent copy from the recovery LUN by copying the data back
to its original location. For servers in a cluster, only Full Resync is
allowed.
LUN Swap reverses roles of the LUNs and turns the recovery LUN
into the production LUN, and the production LUN into a recovery
LUN. This is the fastest option, producing almost immediate results.
After a swap, you may need to create additional recovery LUNs before
you can make new shadow copies. For servers in a cluster, LUN Swap
is not allowed.
CautionWhen you select LUN Swap, the Delete Production Volumes after swap
checkbox is selected. Selecting this checkbox deletes the production
volumes after the swap, which irreversibly deletes your production data.
Important: Use swap only temporarily if your recovery LUNs reside
on less reliable external storage disks because these less reliable disks
become the production LUNs. To swap disks back again, use Business
Copy within Command View to create copies of the current
production LUNs in the original production disk group. Then present
the copied LUNs to the production server, assign drive letters, and
update the database and log path within Exchange.
Delete Selected Copy deletes the selected point-in-time copy without
waiting until after the recovery.
62HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
5. Click Start Recovery. The recovery process begins.
Progress of the recovery displays in the Activity Log panel.
6. When the log panel shows the recovery is finished, click Close to close
the window. Your recovered production LUN should now be ready to
use again.
Using FRS63
Deleting old point-in-time copies
Using the procedure below, you can delete old point-in-time copies any
time your pool of Point-In-Time copies grows too large. HP recommends
you delete the oldest copy first, followed by the next oldest, and so on.
1. Click Recovery on the main window menu bar, and select
Point-in-Time Recovery.
2. Click on a production storage group in the Select Storage Group panel.
A list of point-in-time shadow copies displays in the Point-in-Time

Troubleshooting
This chapter explains how to maintain Fast Recovery Solutions (FRS) on
an EVA disk array and troubleshoot problems or error messages.
Troubleshooting75
Troubleshooting
The following pages present typical problems and solutions as well as
suggested testing methods.
Checking logs
Checking event logs is often the first step when trying to identify problems.
Error messages in the logs may indicate the problem.
• Check application event logs associated with Exchange, FRS, and HP
• Check Windows system event logs.
Common problems and solutions are also listed below.
Troubleshooting checks
The following checks may help you isolate and resolve issues with FRS or
associated systems and software.
1. Ensure the HP Business Copy license and the HP VSS Hardware
VSS Hardware Provider.
Provider were installed and correctly configured.
A simple way to verify the HP VSS HWP is installed correctly, is to
see if it is running. At the command line, enter:
vssadmin list providers
Look for the HP VSS HWP in the resulting list.
2. In order for the production and recovery servers and their applications
to communicate, the Windows DCOM distributed communication
process must be able to communicate among all FRS servers. This
requires that you be logged into all FRS-related applications and all FRS
servers (including Command View) as an administrator and requires
connectivity without a firewall between servers. You can check for
DCOM errors in the system event logs.
3. Check that the Exchange server is online.
76HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
4. Check Cluster administrator and verify resources are online.
5. Check the Command View server for errors associated with the storage
system.
6. Check that the Exchange server can access the data LUNs via My
Computer.
7. Check for mount points found under the FRS directory.
8. If Exchange copies fail because of a failed integrity check, verify that
eseutil.exe and ese.dll are installed on the recovery server. Integrity
checks will not work without them, and a failed integrity check causes
a failed copy.
9. The VSS Hardware Provider may not be able to make the copy because
it has run out of copy space. Return to the disk array and the HP VSS
Hardware Provider Configuration Utility (in Windows
Start/Programs/Hewlett-Packard) to create more shadow copy LUNs
and then re-populate the configuration utility.
10. Bypass FRS and test VSS, HWP, and the array by using the Microsoft
vshadow utility available in the Microsoft VSS Software Developer’s
Kit to create snapshots. See the Microsoft documentation for
instructions. If you can create snapshots without FRS, FRS may not be
properly installed or configured.
FRS does not recognize storage groups
1. Storage groups are not properly set up. See “Chapter 2 Configuration”
page 34 to correctly set up production and recovery storage groups.
Troubleshooting77
FRS error messages
The following text explains FRS error messages.
Maintenance
Error:
Dismounting the local/remote drive failed. Please close any open files on
that drive and select retry to try again, select ignore to ignore the error and
continue, or select abort to cancel the operation.
Explanation:
FRS cannot dismount any file system drive if it sees any activity on the
drive. This could cause corruption, so FRS waits until all files on that drive
are closed before dismounting the drive. Confirm that all files are closed
and select retry.
If the problem is with the remote drive, confirm that all connectivity to the
remote machine is intact and that there are no network issues preventing
FRS from communicating with the remote server.
Error:
Mounting the remote drive failed. Please select retry to try again, select
ignore to ignore and continue, or select abort to cancel the operation.
Explanation:
If FRS was able to dismount a drive, there should be no problem
re-mounting it unless FRS has lost connection to the production server.
Confirm that all connections are intact and that the recovery server can ping
the production server. Then retry.
78HP StorageWorks EVA Fast Recovery Solution for Windows Server 2003: Administration Guide
Recovery
Error:
Extended maintenance mode fix (for clusters) is not installed on node
[production server name].
Explanation:
Before installing HP StorageWorks Fast Recovery Solution (FRS) on a
Microsoft cluster node, Microsoft hot fix KB903650 must be installed on
the cluster node. This hot fix is required on Windows Server 2003 systems
to support the cluster extended maintenance mode.
During recovery, FRS inspects the cluster configuration to check whether
the above hot fix is installed on the production servers. If the hot fix is
installed, the recovery operation proceeds normally. Otherwise the recovery
operation is terminated and the error message above is displayed in the
recovery activity log window and also in the application event log.
Error:
Failure setting the database restore flag. Please select retry to try again.
Explanation:
If FRS cannot reach the exchange server, it cannot manipulate the restore
flag. Check connectivity and network to the production server. Confirm that
all Microsoft services are online.
Error:
This operation cannot be completed, no recovery LUN available.
Explanation:
The recovery button will only be enabled if a split mirror backup has been
done in the past and the pair has been created using FRS. However, if
someone goes into the disk array and manually deletes a pair which was
Troubleshooting79
being managed by FRS, and then a recovery is attempted, this error will be
given.
Error:
Are you sure you want to continue with a recovery?
Explanation:
Once a recovery is started, it cannot be cancelled until the recovery is
complete. The production database will be replaced by the recovery-ready
database and there is no going back to the original if this was not the
intended action.
Terminating processes
Message:
Operation cannot be cancelled…
Explanation:
Closing either the GUI or the progress window for a split mirror backup or
a recovery causes FRS to leave the database in an unknown state. For this
reason, FRS does not allow windows to be closed while an action is in
progress. If the process is forcibly closed through the use of “task
manager,” the integrity of the database cannot be guaranteed, and FRS and
the disk array may have conflicting information about the databases.
