Manual Backup Servers for S8500 or
S8700 Media Servers—R2.0 or later
Please disregard any references to the S8710 Media Server in this
document. The S8700 Media Server is the currently available product. If
you need additional information, please contact your Avaya
representative or Avaya authorized business partner.
A Manual Backup Server(s) (MBS) backs up an existing S8500 Media Server or a S8700 or S8710 Media
Server pair. The MBS resolves two failure situations:
•
When the primary media server(s) fail, meaning Avaya Communication Manager is unable to
control call processing
•
When the network becomes fragmented, meaning the primary media server(s) cannot
communicate with remote location(s)
The MBS does not address other failure situations.
The media server(s) running Avaya Communication Manager the majority of the time is called the
primary media server(s). The active media server(s) is defined as the one(s) running Avaya
Communication Manager at any given time.
The primary media server(s) and MBS must be the same media server type. That is, the S8700 Media
Servers must be backed up with S8700 Media Servers, the S8710 Media Servers must be backed up with
S8710 Media Servers, and the S8500 Media Server must be backed up with an S8500 Media Server. Only
one MBS per primary media server(s) is permitted.
An MBS is available beginning with Release 2.0 of Avaya Communication Manager.
NOTE:
MBS requires a software update (patch) to work with Release 2.0, 2.0.1, or 2.1. Contact
your remote Services Tier 3 team to obtain the required patch.

- Page 2 What is an MBS? What is an MBS? An MBS adds a survivability option to those that already exist for Avaya’s media servers. An MBS is a media server (S8500) or pair of media servers (S8700/S8710) with identical license files and translations in a non-call-processing state.
- Page 3 MBS, which implies that the use of ftpserv on the MBS must cease. This environment must be reestablished after any server configuration changes or software upgrades that affect the MBS. All changes described above must be made by Avaya Services as part of the implementation process due to root access requirements.
- Page 4 Configuring the MBS A script must be added to both the primary media server(s) and the MBS to implement MBS. Avaya Services must configure MBS-related scripts on the primary media server(s) and the MBS because the configuration process requires root access. After the configuration is complete, the following statements are true: •...
- Page 5 Because translations transfer from the primary media server(s) to the MBS, you do not need to perform any administration on the MBS. Have Avaya Services set up the scripts and schedules on the primary media server(s) and MBS. CAUTION: Perform the following steps after Avaya services has completed the configuration on both the primary media server(s) and MBS.
- Page 6 A primary media server(s) is controlling all local and remote port networks. The MBS is not controlling anything (Avaya Communication Manager is down). Using a secure method, the script on the primary media server(s) backs up the security and translation files to the MBS at a scheduled time.
- Page 7 Job Aid: Manual Backup Servers for S8500 or S8700 Media Servers—R2.0 or later Using the MBS If the primary media server(s) fail Before bringing up the MBS, disconnect the primary media server(s) from the control network for repair. Never connect the primary media server(s) back to the control network until the customer can tolerate a service outage and the MBS has been de-activated and disconnected from the control network.
- Page 8 Job Aid: Manual Backup Servers for S8500 or S8700 Media Servers—R2.0 or later Using the MBS NOTE: All translation changes to the MBS while the MBS was in control will be lost and must be re-entered on the active primary media server(s) at this time.

Page 10: Other Configurations
Some of these configurations are legitimate and work fine, but the previous example is what Avaya supports. Be aware that other configurations can result in unwanted service interruptions because two active media servers are trying to control the same IPSI group.
