Upgrade tasks for the first media server
Issue 2.1 June 2006 231
Interchanging the media servers
To interchange the active and standby media servers:
Note:
Note: For Communication Manager Release 3.0 and earlier, interchanging the media
servers does not preserver calls. The Communication Manager reset is
equivalent to a reset system 4. However, if you are upgrading a Release 3.0.1
system and you performed the Pre Upgrade Step, most stable calls are
preserved. Unstable calls and DCS or SIP calls are dropped.
1. Select Status Summary, and check that the Standby Refreshed field says yes.
2. Under Server, click Interchange Servers.
3. To preserve connections during the upgrade, do no select Force interchange regardless
of server status. However, if you must proceed regardless of connections being dropped,
you can select this field.
4. To make the newly upgraded standby server the new active server, click Interchange.
5. To verify that the media server you are connected to is the active server, click Status
Summary.
Note:
Note: At this point, the media servers are on different software loads. Therefore, for
servers upgrading from Communication Manager release 3.0 and earlier,
Standby Refreshed is no and Standby Shadowing is off. For release 3.0.1
servers, these fields show yes and on respectively.
