Doc Text: |
Previously, moving the server from the "communication-interrupted" state to the "partner-down" state did not force the server to take over the partner's leases. Consequently, clients could not get an IP address from the pool of the previously terminated DHCP server. With this update, a failover server in "partner-down" state is able to re-allocate leases to clients.

Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Previously, moving the server from the "communication-interrupted" state to the "partner-down" state did not force the server to take over the partner's leases. Consequently, clients could not get an IP address from the pool of the previously terminated DHCP server. With this update, a failover server in "partner-down" state is able to re-allocate leases to clients. Tested with dhcp-3.0.5-29.el5 using reproducer from comment 0. After stopping the first DHCP server, moving the second one into partner-down state and waiting until MCLT has expired, DHCP client received new IP address from the range, which was originally load-balanced to the first DHCP server. Moving to VERIFIED. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
