Hi,
Is it posible to increase the time it takes for unity to failover to the secondary server. I did notice that failover occurs within 1s of the secondary not been able to contact the primary. This is a requst by one of our customers as they have NIC teaming enabled on their servers. Hence they prefer for NIC teaming to kick in before unity fails over
Solved! Go to Solution.

Unity: Configuring a Dual NIC
To Configure a Dual NIC in the Cisco Unity Server
--------------------------------------------------------------------------------
Step 1 Start the NIC-configuration utility:
a. On the Windows Start menu, click Settings > Control Panel.
b. Choose the applicable option, depending on the server model and NIC brand:
Hewlett-Packard or Cisco MCS server
with model number ending in "H" Click HP Network.
IBM or Cisco MCS server
with model number ending in "I" â¢For a Broadcom dual NIC, click Broadcom Control Suite 2.
â¢For an Intel dual NIC, click Intel(R) PROSet Wired.
Step 2 Configure the dual NIC-or verify the configuration-so that the following conditions are met:
â¢Both NICs are connected to the same network segment (in other words, both are connected to the same Layer 3 subnet and the same Layer 2 Ethernet broadcast domain).
â¢Both share the same IP address.
â¢Both are set up for AFT or for NFT. Refer to the NIC-configuration utility Help.
Step 3 Write down the MAC address that now applies to both NICs. You will need it when you obtain license files in the "Obtaining Cisco Unity License Files" section.
Step 4 Restart the Cisco Unity server for any changes to take effect.
Intervals for Failover and Failback
Failover Interval
When failover occurs, the time it takes for the secondary server to begin answering calls typically depends on what causes failover as described below;
Network outage
The secondary server begins answering calls after waiting for the number of keep-alive events set in the Missed Events Before Failover field in the Failover Monitor. The time required depends on the value of the field and on the value of the Interval (ms) field.
