Mismatched log files have been detected. You are restoring
to a recovery server that has a different set of log files. Log file replay
cannot succeed unless all signatures match.
You will receive the following phrase in the event
Information Store (number) The log signature of the
existing logfile E0n.log does not match the logfiles from the backup set. Logfile
replay cannot succeed unless all signatures match.
The basic reason for the event is that the E0n.log file (the
current log file for the storage group, such as E00.log) has a different log
signature than the log files that have been restored from the online restore.
A typical scenario for this to happen is as follows. All the information
store service files have been removed. In order to restore an online backup of
an Exchange computer, you must have the Microsoft Information Store
running. If you have not checked “Do not mount this store at start-up” on the
Database tab, and you start the Information Store service, then a new E00.log
file is created. The log signature for this file does not match the
signatures of the log files from the backup, and the Information Store fails to
replay logs and mount the databases.
Dismount all the databases in the storage group. Do
an offline backup and then remove all Information Store log files and check files
for the storage group. Check “Do not mount this store at
start-up” on the Database tab for all databases in the storage group.
Start the Information Store service. Uncheck “Do not mount this store at
start-up” on the Database tab for all databases in the storage group. Perform
the online restore.
