Symptoms

Loading sys config triggered by MCPD start might fail after removing NICs for VE if the given NICs have been configured as the data-plane interfaces in BIG-IP Virtual Edition (VE).

Impact

BIG-IP VE stops working. BIG-IP VE cannot be in ready state since almost all other services depend on MCPD to be up running first.

Conditions

- BIG-IP VE. - Multi-NICs have been configured as the data-plane interfaces. - One or some of these NICs have been removed from the host side.

Workaround

Edit /config/bigip_base.conf to delete the net interfaces that have been removed on the host/hypervisor side. To work around this issue, you can edit the /config/bigip_base.conf file and remove the interface that is causing the error. To do so, perform the following procedure: Impact of workaround: Performing the following procedure should not have a negative impact on your system. 1. Log in to the Advanced Shell (bash) of the BIG-IP VE system. 2. Use a text editor to open the /config/bigip_base.conf file. 3. Look for an entry that uses the following syntax: net interface <number> { media-fixed <setting> } For example: net interface 1.2 { media-fixed 10000T-FD } 4. Delete the stanza. 5. Save the text file. 6. Load the configuration by typing the following command: tmsh load sys config
