Multistore failover

I'm trying to wrap my head around vfiler configs in HA pairs. I've fount bits and pieces in various docs but haven't found a comprehensive guide.

Exactly how does a vfiler failover between nodes? What do I need to make this work? Could someone provide example rc files?

Here is where I'm at:

FilerA has several vlans on vif0: 101, 102 103 104

FilerB has the same vlans defined

FilerA has several vfilers with ipspaces:

vfA1, ipspace ip-vfA1 vif0-101 10.0.0.1/24

vfA2, ipspace ip-vfA2 vif0-102 10.0.2.1/24

FilerB has several vfilers with ipspaces:

vfB1, ipspace ip-vfB1 vif0-103 10.0.0.1/8

vfB2, ipspace ip-vfB2 vif0-104 10.0.3.1/24

All ipspaces on both filers with same interfaces

The ifconfig lines in the rc files specify the partner interfaces, e.g.

on FilerA.:ifconfig vif0-102 10.0.2.1 netmask 255.255.255.0 partner vif0-102

on FilerB: ifconfig vif0-102 10.0.2.4 netmask 255.255.255.0 partner vif0-102

The owning filer's rc file has the default route for each vfiler specified with a vfiler run and a default route for default-ipspace.

When I failover, the interfaces don't work on the vfilers. I see this on the console of the takeover filer:

Mon Apr  4 17:35:38 GMT [FilerB: net.ifconfig.noPartner:error]: ifconfig: 'vif0-102' cannot be configured: Address does not match any partner interface.

Does the partner need an ip assigned to it's interface (on the same subnet as the primary)? I tried this but it didn't work:

FilerB> ifconfig vif0-102 10.0.2.4 netmask 255.255.255..0
ifconfig: can't assign address to vif0-102, no vfiler in this interface's ipspace (ip-vfA2) has this address

So it looks like the rc file ifconfigs won't work the way I have them on the partners.

If I try to configure a shared interface in System Manager on the partner, it insists on an ip but fails because there is no vfiler on the partner in that ipspace. Everything in the default-ipspace works fine.

That should work.. Test a failover.
