Chapter 6 Configuring Real Servers and Server Farms
Configuring Server Farms
Resume Service
(Seconds)
This field appears only when the Inband-Health Check is set to Remove.
Enter the number of seconds after a server has been marked as failed to reconsider it for sending
live connections. Valid entries are integers from 30 to 3600. By default, this field is not configured.
The setting of this option affects the behavior of the real server in the inband failed state, as follows:
When this field is not configured, the real server remains in the failed state until you manually
suspend and then reactivate it.
When this field is not configured and then you configure this option with an integer between
30 and 3,600, the failed real server immediately transitions to the Operational state.
When you configure this field and then increase the value, the real server remains in the failed
state for the duration of the previously-configured value. The new value takes effect the next
time the real server transitions to the failed state.
When you configure this field and then decrease the value, the failed real server immediately
transitions to the Operational state.
When you configure this field with an integer between 30 and 3,600 and then reset it deleting
the value from the field, the real server remains in the failed state for the duration of the
previously-configured value. The unconfigured setting takes effect the next time the real server
transitions to the failed state. Then the real server remains in the failed state until you manually
suspend and then reactivate it.
When you change this field within the reset-time interval and the real server is in the
OPERATIONAL state with several connection failures, the new threshold interval takes effect
the next time that a connection error occurs, even if it occurs within the current reset-time
interval.
Transparent This field appears only for real servers identified as host servers.
Check the check box to specify that network address translation from the VIP address to the server
IP is to occur. Clear the check box to indicates that network address translation from the VIP address
to the server IP address is not to occur (default).
Partial-Threshold
Percentage
This field appears only for host server farms.
Enter the minimum percentage of real servers in the primary server farm that must remain active
for the server farm to stay up. If the percentage of active real servers falls below this threshold, the
ACE takes the server farm out of service. Valid entries are integers from 0 to 99.
After you configure a value in this field, enter a value in the Back Inservice field to bring the
primary server farm back into service.
