Redundant Config

Hi ,

 

When you try to fail over the box to the other one by disabling the Network connection but you still have the failover console cable connected it will not fail over. So if you want to test the fail-over first remove the fail-over console cable and then try this by switching off the Active unit.

 

With your current configuration the two boxes are synced? The Active/standby configuration is done properly? the active box and the stand by box shows their proper status? If all the configuration is fine and the two boxes are properly synced only then the fail over will work. It will be better if you can share the configuration that you have done or u want to do.

 

 

 

 

 

 

Regards,

 

ACTIVE BOX:

 

 

self 100.200.44.253 {

 

netmask 255.255.255.0

 

vlan Internal

 

allow default

 

}

 

failover {

 

force active enable

 

peer mgmt addr 100.200.43.254

 

unicast peer Standby_Self_IP {

 

dest addr 100.200.44.254

 

port 1026

 

source addr 100.200.44.253

 

}

 

}

 

statemirror {

 

addr 100.200.44.253

 

peer addr 100.200.44.254

 

 

 

 

 

STANDBY BOX:

 

 

self 100.200.44.254 {

 

netmask 255.255.255.0

 

vlan Internal

 

allow default

 

}

 

failover {

 

force standby enable

 

peer mgmt addr 100.200.43.253

 

unit 2

 

unicast peer Active_Self_IP {

 

dest addr 100.200.44.253

 

port 1026

 

source addr 100.200.44.254

 

}

 

}

 

statemirror {

 

addr 100.200.44.254

 

peer addr 100.200.44.253

what's interface 1.1?

 

 

if u'd like to failover when vlan is down, u need vlan failsafe.

btw, pls make sure ha vlan is never down since both units will go active.

 

You still did not mention about the fail-over console cable. Also for the network fail-over connect the ports directly through a small patch cord and reply what is happening to your setup.

If you manually fail over, will it be successful? You can use "b fo standby" command or do it from the admin ui.

 

 

You can also check the output from the logs /var/log/ltm from both units to see the status of the link up/down and failover switching.

 

 

And what is port 1.1?

Port 1.1 is the internal VLAN, and it the only port in use on this unit at the moment.

 

 

As Moo suggested, can you fail over manually using 'b fo standby' or by forcing the active unit to standby in the GUI?

 

 

Also, I wouldn't suggest setting a redundancy preference as this can lead to an additional, unnecessary fail over when the preferred active unit fails, the peer becomes active and then the preferred active unit comes back online.

Since the units are remote, I found out the serial cable is plugged in.

 

 

Had someone disconnect it. I will test network failover again over the weekend.

 

 

 

if u need to failover when 1.1 is down, i understand u've to configure vlan failsafe or ha group. it will work with serial failover too.

 

 

cheer!

As the failover console cable is disconnected I believe it will work now..... cheers... do update us....
