Fixing database or software corruption
Software or database corruption can occur due to user
error, hardware failure, or software problems. Use the
following procedures to fix database or software
corruption.
Database restore: If the database is faulty and the
information that is programmed in the database is
corrupted, restore the database from the latest database
backup.
Software and database restore: If a database restore
does not return the system to normal operation, perform
a software and database restore from the latest software
and database backup. You would also perform a
software and database restore after replacing a faulty
hard drive.
Previous software and database restore: During an
upgrade, the system automatically takes a backup of the
system software and database and places it on the hard
drive. If a software upgrade fails, you can go back to the
previous version of software and database by using the
CONFIG and RESET switches. See Restoring the
system with previous software (p. 155).
Factory software and database restore: You can
restore the factory version of the software and database
using the CONFIG and RESET switches. See Restoring
the system with the factory software (p. 156).
Voice mail data restore: If you need to recover a voice
mail database, perform a voice mail data restore.
If you have changed the default DNS Host name of the
system, you must reprogram it after a database restore.
