XADM: Isinteg Has Been Modified to Dump the Mailbox Table (231967)
The information in this article applies to:
- Microsoft Exchange Server 5.5
This article was previously published under Q231967 SYMPTOMS
In a disaster recovery situation, when the only backup available is a few days old, there is no mechanism for determining whether the best procedure is to restore the old backup, or to try running the utilities (Eseutil and Isinteg) to repair the database. The problem is that the utilities can end up removing information (pages) from the database, and there no way of telling which actual users (mailboxes) have been affected. Determining which users are affected by the repair may be useful in making the decision to try and repair the database, as opposed to restoring the old backup.
This modification is no substitute for a correctly implemented disaster recovery strategy. Restoring from a recent backup should always be the preferred method for coping with a disaster recovery scenario.
CAUSE
Isinteg has been modified to additionally dump the Mailbox table of the database. Previously the Isinteg -dump option would dump the Index Age and Folder tables, but now it also dumps the Mailbox table.
This additional information can be used in the following manner to manually determine which users have lost information from a database repair.
- After running Eseutil to repair the database, that is, eseutil /p database name /v /x, check the display and Repair.txt file in the same directory. If you see lines in the file such as:
Inserting page 62 into BadPages table
Creating new FDP with 3 pages starting at 246
Table Msg (14). new pgnoFDP is 246
- When running Isinteg to check the integrity of the database, that is isinteg -pri -fix -detailed -verbose -test alltests, check the Isinteg.pri file in the same directory. If you see lines such as:
Fix: MsgFolder 1 (FID=0001-000000000144, MID=0001-000000000167, INID=0001-0000000010E9): Deleting this MsgFolder row
- Now run Isinteg in dump mode, that is, isinteg -pri -dump, and check the Isinteg.pri file in the same directory. Look up the FID in the dump of the Folder table and obtain the Root FID of the folder:
[36] Folder FID=0001-000000000144
Parent FID=0001-000000000141
