Compute or storage controllers do not receive IP when v2 switch reboots

When a v2 switch loses power and reboots, an internal race condition might prevent the compute or storage controllers from receiving an IP address.

The workaround is to restart the DHCP server on the network switch in this scenario.

Note

This issue only affects customers still on v2.

To resolve the issue, follow these steps:

1. Execute the following command to check tacp-ovs-monitor is running:

   sudo service tacp-ovs-monitor status

2. If tacp-ovs-monitor is not running, start it by executing the following command:

   sudo service tacp-ovs-monitor start

3. Execute the following command to restart the DHCP server:

   sudo service isc-dhcp-server restart
