This topic provides information about restoring backed-up Avaya™
S3400 Message Server files and is organized as follows:
About restoring backed-up system files
The data stored on DVD-RAM media during the unattended or attended
backup is used to restore the system to an operational state. The
backup media contains both Message Storage Server (MSS) and Message
Application Server (MAS) data.
If a system problem or failure occurs, backups can be invaluable
in returning the system to an operational state. You are likely
to restore backups when directed to do so by an alarm repair action.
Depending on the severity of the situation, system software might
have to be reinstalled on the MSS before you can restore data from
the backup media.
Performing a restore
Depending on the amount of data on the system, it usually takes
between 15 and 60 minutes to restore data to the MSS from one DVD-RAM
medium.
To restore system data:
- Stop the messaging software.
- Locate the backup medium or media that contains the
data to be restored.
- Insert the backup medium in to the DVD-RAM drive.
|
Note: If you are restoring data from multiple
DVD-RAM media, make sure you insert the medium labeled
"DVD #1" first.
|
- From the Messaging Administration main
menu, select:
Utilities
Backup and Restore
Restore
The system displays the Restore page.
|
Note: The system might notify you that you need
to reinstall system software before continuing with data
restoration. If so, note which software packages you must
reinstall and see Adding software
packages for these procedures.
|
- For each data type that you want to restore, select Yes from
the drop-down list for that data type. Yes is the default setting
for all data types.
- For each data type that you do not want to restore, select
No from the drop-down list for that data type.
- Click Save to restore the selected data types.
|
Note: If you are not performing the restore
from the console, the system displays a warning message
that states that leaving the Restore page will abort the
restore. Click OK to acknowledge the warning message.
|
The system displays the SSH User Authentication dialog box.
-
Enter your login, for example, sa, in the User name field and
your password in the Password field.
-
Click Login.
|
Note: If you are performing the restore from
the console, the system displays a warning message that
states that leaving the Restore page will abort the restore.
Click OK to acknowledge the warning message.
|
The system displays restore information as it prepares for the
restore and then displays the following message:
****************************************************************************
Please insert DVD or CD-ROM number 1
****************************************************************************
Press Enter to continue or ^C (Control C) to quit:
- Press Enter.
The system begins to restore data from the backup medium.
When the restore is complete, the system displays the following
message:
Restore completed successfully - Day, Date, and Time
- If the restore completed successfully, continue with Step 12.
If the process was not successful, the log contains an
explanation of why the restore process failed. See Verifying
the restore. If the restore process was unsuccessful, do the
following:
- Return to Step 2 and attempt the restore again.
- If the process fails a second time, access the Alarm log
and determine if there are any active alarms in the log. See
Alarms and follow the associated
repair actions for any active alarms.
- If you do not have any remote networked machines, continue
with Step 13. If you have remote networked machines, do the following:
- Click Return to Main.
- Run a manual update to and from all remote networked machines
to correct any database inconsistencies. See
Performing remote subscriber updates manually.
- Continue with Step 13.
-
Click Return to Main to return to the Messaging Administration main
menu.
- Reboot the system.
- Restore MAS data, if necessary. See Restoring
backed-up MAS data.
Verifying the restore
To verify the restore:
- Start at the Messaging Administration main
menu and select:
Logs
Backup and Restore Logs
View
Restore Log
The system displays the View Restore Logs page, which contains
a drop-down list with the available restore logs.
- Select the restore log that you want to view and click
View.
The system displays the View Restore Logs page, which contains
a list of all the files that were restored and information about
any errors that occurred during the restore.
- Scroll to the end of the restore log and verify that
there is an entry with the following text:
Restore completed successfully - Day, Date, and Time
If the restore was not successful, the log contains an explanation
of why the restore process failed.
-
Click Return to Main to return to the Messaging Administration main
menu.
Recovering from an MSS system failure
If a previously operational MSS has become corrupted and will not
boot (for example, after a power failure), follow the procedure
described in Appendix D of the Installation
guide (pdf). The MSS recovery procedure is summarized below.
To restore an MSS that has suffered a system failure:
- If the MSS had a catastrophic failure of all hard disks, replace
all faulty drives, and then power the system back up. See:
- Install the operating system on the MSS. See Appendix D of the
Installation guide
(pdf).
- After the system boots, restore the system data from the latest
backup. See Performing a restore.
- If the MAS event log shows
1663 events, the front end database (FEDB) on the MAS must be
manually resynchronized with the MSS. To do this, contact your remote support center.
