User manual POLYCOM KIRK WIRELESS SERVER 6000 APPLICATION NOTE CONFIGURING THE REDUNDANCY FEATURE V1.3

[. . . ] The redundancy feature is designed to be as non-intrusive as possible. Except for a few simple redundancy options, configuration and administration of a redundant solution is not different from a single server solution. All configurations are executed on the master, and everything is presented in the same familiar menus. Configuration data and statistics are automatically propagated between all the KIRK Wireless Server 6000 entities, e. g. [. . . ] Be aware that if a license is installed on the master KIRK Wireless Server 6000, a corresponding license must be installed on the backup KIRK Wireless Server 6000. For example, if a 500 users license is installed on the master, a 500 users license must be installed on the backup as well. License required on the master: 14075250 ­ Software license for master KIRK Wireless Server 6000 redundancy. License required on the backup: 14075260 ­ Software license for backup KIRK Wireless Server 6000 redundancy. Configuration of the redundancy feature is performed in the Configuration > Redundancy menu. Configuring a Master KIRK Wireless Server 6000 The master KIRK Wireless Server 6000 must be configured as a normal single server solution, and it must be verified that the desired functionality is working. Then it can be Page | 2 Configuring the Redundancy Feature in a Polycom® KIRK® Wireless Server 6000 extended to a redundant solution. On the master KIRK Wireless Server 6000, set the node type to `Master' and then configure the IP address of the backup KIRK Wireless Server 6000. Configuring a Backup KIRK Wireless Server 6000 On the backup KIRK Wireless Server 6000 only basic network settings and redundancy settings need to be configured. All other settings are retrieved from the master KIRK Wireless Server 6000. Set the backup node type to `Slave', configure the IP address of the master and then reboot the KIRK Wireless Server 6000. Following this step, all other configuration settings will be unavailable in the GUI. Note: Please note that if the internal corporate phone book feature on the KIRK Wireless Server 6000 is to be used together with the redundancy feature, the corporate phone book needs to be configured for LDAP. If the internal corporate phone book is configured to use a comma separated file, it will not be compatible with the redundancy feature. Server settings The following server settings must be used to configure the redundancy features: Setting Failover time Configuration key redundancy. failover_time (integer) Description The time in seconds from the KIRK Wireless Server 6000 detects a failure until it initiates a failover operation. (See the fact box Failover time conditions on the following page). The hostname or IP address of the peer KIRK Wireless Server 6000. The peer address signifies the other KIRK Wireless Server 6000 in the solution, i. e. on the master server, it must be set to the address of the backup (slave) KIRK Wireless Server 6000, and on the backup server it must be set to the address of the master KIRK Wireless Server 6000. Unique ID of the distributed database of the solution, which must match for replication to be performed. When reset on the master server, the UUID is automatically generated, and when reset on the backup server, it is retrieved from the master server. The UUID must be reset when a master KIRK Wireless Server 6000 is changed to a backup KIRK Wireless Server 6000or when a backup KIRK Wireless Server 6000is moved to another solution. Page | 3 Peer address redundancy. peer (string) Database UUID redundancy. database_uuid (string) Configuring the Redundancy Feature in a Polycom® KIRK® Wireless Server 6000 Setting Mode Configuration key redundancy. mode (string: single/master/slave) Description The mode of the KIRK Wireless Server 6000: Either a normal single server solution, a master or a backup (slave) in a redundant solution. Base station and media resource configuration The base stations and media resource should be configured just as in a single KIRK Wireless Server 6000 solution, and the server address should be set to the address of the master KIRK Wireless Server 6000. [. . . ] Please be aware that if for some reason a repaired or replaced former master KIRK Wireless server 6000 is re-instated as master, it should be done very carefully. First, it must be configured as a backup KIRK Wireless server 6000 in order to get the current user data and configuration from the acting master KIRK Wireless server 6000 (i. e. Subsequently, when all data are replicated from the acting master to the original master, the acting master can be demoted to backup server, and the acting backup server (i. e. the original master) can be re-instated as master KIRK Wireless server 6000. Failure on the Backup KIRK Wireless Server 6000 A failure of the backup KIRK Wireless Server 6000 will induce a short service outage, and the master KIRK Wireless Server 6000 will reestablish full operation as a single server solution.
