[BlueOnyx:16117] Re: Redundancy and using two network cards

[Richard Morgan :: Morgan Web]

Hi Guys, many thanks for your answers...

 

Tobias, yes, this sounds like what I was looking for and I will definitely
have a go and getting this working.  However as the server is a four hour
drive away I don't think I'll be messing with the network config remotely.
I was, somewhat naively, hoping it was as simple as setting the same IP for
the second NIC.

 

Chris, appreciated the detailed answer too.  Great common sense approach to
not get wrapped up in the issue.  I chatted with one of the techy guys in
the data centre and with all the hot-swap/failover stuff they have the
chances of a prolonged outage are rare - their business relies on keeping
thing working.

 

Always appreciated.

 

Cheers, Richard

Hi Richard,

 

what you are looking for is bonding your interfaces. There is a mode called
active-passive that would do what you want.

 

While it is not very complicated it is not very easy to do if doing it the
first time. Here you can find more information:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm
l/Deployment_Guide/s2-networkscripts-interfaces-chan.html

 

And I don't know how to tell BO to use the new interface that you will be
creating, maybe somebody else can help.

 

 

Tobias

Hi, hope this is simple.

 

In the data centre we use, we've been provided two network cables to connect
to the server which come from separate switches/routers to provide
redundancy.  At the moment we're only using one of these cables, but we'd
like to be able to use both.

 

How do I configure the network settings to allow both network ports to be
used with the same IP address?  I'm not interested in teaming for speed,
just the redundancy in case one of the data centre's switches fails.

 

Thanks

 

Richard
