Description: Information Store (3752) The streaming page read from the file &quot;F:\Program Files\Exchsrvr\mdbdata\Executives.stm&quot; at offset 52408320 (0x00000000031fb000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 3750803089 (0xdf90b691) and the actual checksum was 2716766160 (0xa1ee8fd0). The read operation will fail with error -613 (0xfffffd9b). If this condition persists then please restore the database from a previous backup.  When you try to back up the information store on an active or on a passive Cluster service by using Veritas Netbackup, the backup is unsuccessful. A status code of 1 is returned. This status code means &quot;partial success.&quot; You receive the following error message:

081701.LOG:08/17/01 11:52:23 PM: [6652]: ERR - XCHG_BackupRead FS_ReadObj Failed! 0xFFFFFE30:FS_COMM_FAILURE 081701.LOG:08/17/01 11:52:23 PM: [6652]: ERR - failure reading Exchange 2000 object: Microsoft Information Store:\S2-SG1\S2-SG1-MS5-Std (0xFFFFFE30:FS_COMM_FAILURE)

 When you try to back up a remote information store by using Veritas Netbackup, the backup is unsuccessful. There are no events that are listed in the Application log that indicate a problem. However, the Veritas Netbackup log contains error information that is similar to the following:

<pre class="fixed_text">Unable to attach to \\Servername\Microsoft Information Store\First Storage Group.

The item was not found.

</li></ul>

<div class="cause_section">

CAUSE
These problems can occur for one or more of the following reasons: <ul> There is a problem with the hard disk or with the hard disk controller.</li> There is a problem or an incompatibility with the back-up program.</li> There is a problem or an incompatibility with an installed third-party event sink.</li> The information store database is damaged or corrupted.

In certain database operations, including, but not limited to online backup, the back-up routine makes a call to the operating system. This call is made to read a 4 kilobyte (KB) page of data from the database on the disk and then write the data to tape. Before the online backup process writes the data that is returned from the operating system call to tape, the online backup process reads the checksum value in the page header. The checksum value in the page header is recorded when this page is written to disk. The online backup process compares the checksum value in the page header to the value that is returned from the READ call. If the checksum values do not match, the Microsoft Jet Database Engine returns error -613.

The checksum error occurs in an SLV file during backup. SLV means a streaming file or an .stm file. Error &quot;-613, JET_errSLVReadVerifyFailure&quot; is similar to error &quot;-1018, JET_errReadVerifyFailure.&quot; Exchange Server 2000 logs error &quot;-613&quot; for checksum errors on the .stm database file. Exchange Server 2000 logs error &quot;-1018&quot; for checksum errors on the .edb database file.

RESOLUTION
To resolve this problem, follow these steps:

Troubleshoot hardware problems

 * 1) View the System log to determine whether disk I/O errors are listed.
 * 2) Obtain available firmware updates or driver updates for your hard disk drive controllers.
 * 3) Run the Chkdsk utility to determine whether a problem exists with the hard disk drives.

Troubleshoot your back-up program
<ol> Try to back up the information store by using the Microsoft Windows NTBackup program that is included with Microsoft Windows 2000.

If you can successfully back up the information store by using the Windows NTBackup program, this may indicate that a problem exists with your back-up program.</li> Contact the manufacturer of your back-up program to obtain updates or patches that may help resolve this problem.

For information about how to contact the manufacturer of your back-up program, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base:

</li></ol>

Uninstall third-party event sinks

 * 1) Uninstall any third-party event sinks.
 * 2) If you can, move the mailboxes to new blank databases.
 * 3) Try to back up the databases by using the Windows NTBackup program.
 * 4) If you are successful using the Windows NTBackup program, try to use your third-party back-up program.

<div class="status_section">

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.

<div class="moreinformation_section">

MORE INFORMATION
To do additional troubleshooting, follow these steps:

Determine the RestrictAnonymous registry value
If you cannot do a successful remote backup, determine whether the  registry value is set to 1 or to 0. The  registry value must be set to 0 to permit an anonymous Lightweight Directory Access Protocol (LDAP) query against the information store.

For additional information about how to use the RestrictAnonymous registry value, click the following article number to view the article in the Microsoft Knowledge Base:

246261 How to use the RestrictAnonymous registry value in Windows 2000

Defragment and repair the information store database
<ol> Troubleshoot any hardware problems that may cause an information store database problem.</li> Dismount the mailbox store.</li> Perform an off-line backup of the .edb Information Store database and of the .stm Information Store database.

For additional information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:

296788 Offline backup and restoration procedures for Exchange

You can back up the .edb database files and the .stm database files to tape or to another location. Alternatively, you can copy the databases to another folder or to another volume by using the Esefile utility. The Esefile utility is available on the Exchange 2000 Server CD-ROM in the Support\Utils\i386 folder.

For additional information about how to use the Esefile utility, click the following article number to view the article in the Microsoft Knowledge Base:

248406 Esefile support utility for Exchange Server 5.5 and Exchange 2000 Server

</li> Perform an off-line defragmentation of the database.

You want to do this to recover the database from checksum errors. To do an off-line defragmentation of a database that is 4 gigabytes (GB) to 6 GB takes about an hour. You also have to have about 110 percent of the size of the database available as free hard disk space to perform the off-line defragmentation of the database.

For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

192185 How to defragment with the Eseutil utility (Eseutil.exe)

</li> Run the Esefile utility against the defragmented .edb database and the defragmented .stm database to perform the checksum error verification.</li> If no checksum errors occur, mount the database. Try to perform an online backup of the database.</li> Do a &quot;hard&quot; repair of the database if any one of the following problems occur: <ul> You cannot do an online backup.</li> You cannot do an off-line defragmentation.</li> You have checksum errors in your database.</li></ul>

The &quot;hard&quot; repair of a 4 GB to 6 GB database takes about an hour.

Note This procedure causes some mailbox data loss. This is because the 4 KB pages that fail checksum error verification are deleted. For more information about how to perform a &quot;hard&quot; repair of a database, click the following article number to view the article in the Microsoft Knowledge Base:

259851 Ramifications of running the eseutil /p or edbutil /d /r command in Exchange

</li> <li>After the &quot;hard&quot; repair of the database operation is successfully completed, repeat steps 4 and 5 to perform an offline defragmentation of the database.

Note A repaired database must not be left in production. While the /d switch is used with the Eseutil utility to defragment a database, what the Eseutil utility actually does is create a new database that stores the defragmented information. Then, the Eseutil utility replaces the existing database with the new copy. This is a good idea in case the existing database structure is corrupted.</li> <li>After the defragmentation of the database is successfully completed, run the Isinteg utility against the repaired database to detect and to fix logical errors in the information store. These logical errors may be the result of the &quot;hard&quot; repair of the database operation. The Isinteg utility can process about 4 GB to 6 GB of data per hour.

By default, the Isinteg utility is located in the Program Files\Exchsrvr\Bin folder on the drive where Exchange 2000 Server is installed.

The following command shows the syntax that is used to run the Isinteg utility:

isinteg -s  -verbose -fix -test alltests -l

For example, type the following command where  is the name of your Exchange 2000 Server:

isinteg -s  -fix -test alltests -verbose -l c:\isinteg1.log </li> <li>Type the number of the unmounted information store that you want, and then press ENTER.</li> <li>Examine the log file that is produced by the Isinteg utility. Continue to run the Isinteg utility until the number of fixes and the number of errors in the log file equals 0 (zero) or until the number of errors and the number of fixes do not change.

Note Specify a different name for the log file every time that you run the Isinteg utility.</li> <li>Repeat step 4 and step 5 to perform an off-line defragmentation of the database.

Note A repaired database must not be left in production. While the /d switch is used with the Eseutil utility to defragment a database, what the Eseutil utility actually does is create a new database that stores the defragmented information. Then, the Eseutil utility replaces the existing database with this new copy. This is a good idea in case the existing database structure is corrupted.</li></ol>
