Hi all -
I have a bit of a throw-back question. I swear I've read all the docs availalbe (HA 7-mode config guide, system admin guide, network mangement guide, ethernet storage design TR) but I am still confused on how to properly configure a 7mode HA VIF failover in a situation where you only have one VIF that needs to float to a standby controller. Support tells me this is "not a common configuration" and that the solution is to have a data IP on both controllers, even if both controllers are not being used in active/active. I realize that I can do an ifconfig on each controller, with the partner option specifying the other node's IP/interface. However, this particular filer is just a large aggregate, single volume, single NFS access IP. So I don't see a point to having a data IP on the other controller...
According to the ifconfig man page ( https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_ifconfig.1.html), this is possible:
"On a node in an HA pair, a network interface performs one of these roles: ...
A standby network interface for the partner. That is, if the partner fails, the network interface works on behalf of the partner. When the node is not in takeover mode, the network interface is idle. A network interface performs this role if it does not have a local IP address but a partner IP address, which you assign by the *partner* option of the *ifconfig* command.
The node maps a partner IP address to a shared or standby interface when the node initiates a takeover operation. In takeover mode, all requests destined for the partner IP address are serviced by the shared or standby interface. Also, in partner mode, if a command takes a network interface name as an argument, enter the network interface name of the failed node. The command is executed on the shared or standby interface on the live node. Similarly, in partner mode, a command for displaying network interface information displays the network interface name of the failed node, even though the command is serviced by the shared or standby interface on the live node."
Help me think this through. This means if I want filer1 to be active and filer2 to be standby with a sinlge VIF, filer1 would have something like 'ifconfig e0a 10.10.10.10', while filer2 would have something like 'ifconfig e0a partner 10.10.10.10'?
If I recall, something like this:
node1: ifgrp create lacp ifgrp0 -b ip e3a e3b ifconfig ifgrp0 192.168.10.10 netmask 255.255.255.0 partner ifgrp0
Node2: ifgrp create lacp ifgrp0 -b ip e3a e3b (no ifconfig here, unless you need jumbo frames, turning off flow-control/pause frames, etc)
Obvivously, if you need jumbo frames or other elements and routing, add it in. If you need it on the partner, just execute the ifconfig commands to set those.
It is that simple.

Phil,
You’re correct. If filer2 has no data volumes, then there’s no good reason to have a “data IP” on filer2.
The ifconfig statement you really want in your /etc/rc is something like the following:
filer1> ifconfig e0a <IP-address> netmask <mask> partner e0a
This lets filer1’s IP address move to filer2’s interface e0a during a takeover. While using the same interface (e.g. e0a) in both controllers is not required, this symmetrical use of interfaces is good management practice.
Your suggestion of “ifconfig e0a 10.10.10.10” on filer1 means “Let interface e0a of filer1 takeover the IP address 10.10.10.10 of filer2 for the duration of the takeover”, which doesn’t sound like what you want.
Since you did mention VIF, while your example only shows bare ports, you should remember to create the ifgrp/vif on both filer1 and filer2 if you’re going to use that.
More comprehensive explanation is here. https://library.netapp.com/ecmdocs/ECMP1210206/html/GUID-525FCF4E-109D-4E6F-... Francis Kim fkim@berkcom.commailto:fkim@berkcom.com

Thanks Tim/Francis. Yes we are using interface groups, I was just trying to simplify things a lot.
I'm still confused though because that is how we currently have it set up, yet the VIF still fails to migrate. In the messages log, it states "ifconfig: 'vif_orig_data' cannot be configured: Address does not match any partner interface."
Here is filer1's (active) /etc/rc: hostname filer1 ifgrp create single vif_orig_data e0b e0a ifconfig e0M `hostname`-e0M netmask 255.255.0.0 mtusize 1500 ifconfig vif_orig_data `hostname`-vif_orig_data netmask 255.255.255.0 partner vif_orig_data mtusize 1500 trusted -wins up route add default 10.10.10.254 1 routed on options dns.enable on options nis.enable off savecore
And here is filer2's (standby) /etc/rc: hostname filer2 ifgrp create single vif_orig_data e0b e0a ifconfig e0M `hostname`-e0M netmask 255.255.255.0 mtusize 1500 route add default 10.10.10.254 1 routed on options dns.enable on options nis.enable off savecore
When I read this line from the ifconfig man page "A network interface performs this role if it does not have a local IP address but a partner IP address, which you assign by the *partner* option of the *ifconfig* command" it sounds to me like you would run "ifconfig vif_orig_data partner vif_orig_data" on the standby node, and remove the partner option from the active node.

You need a partner statement on filer2. When filer2 takes over filer1 it has to know which interface to use when taking over the partner interfaces.
Add this to the rc on filer2 after your ifgrp create line:
ifconfig vif_orig_data partner vif_orig_data
So now the rc file on filer2 should look like this:
hostname filer2 ifgrp create single vif_orig_data e0b e0a ifconfig vif_orig_data partner vif_orig_data ifconfig e0M `hostname`-e0M netmask 255.255.255.0 mtusize 1500 route add default 10.10.10.254 1 routed on options dns.enable on options nis.enable off savecore
You will then need to run the same command on the cli:
filer2> ifconfig vif_orig_data partner vif_orig_data
The reason for running the command is that you need for the word "partner" to show up in the "ifconfig -a" output under the vif_orig_data interface. Think of the ifconfig -a output as a "running config".

I suppose you could, but it's not really needed. The mtusize is set on filer1. All you are doing on filer2 is telling the interface where to land.

The reason for running the command is that you need for the word "partner" to show up in the "ifconfig -a" output under the vif_orig_data interface. Think of the ifconfig -a output as a "running config".

I'm still confused though because that is how we currently have it set up, yet the VIF still fails to migrate. In the messages log, it states "ifconfig: 'vif_orig_data' cannot be configured: Address does not match any partner interface."

When I read this line from the ifconfig man page "A network interface performs this role if it does not have a local IP address but a partner IP address, which you assign by the *partner* option of the *ifconfig* command" it sounds to me like you would run "ifconfig vif_orig_data partner vif_orig_data" on the standby node, and remove the partner option from the active node.

Phil,
You’re correct. If filer2 has no data volumes, then there’s no good reason to have a “data IP” on filer2.
The ifconfig statement you really want in your /etc/rc is something like the following:
filer1> ifconfig e0a <IP-address> netmask <mask> partner e0a
This lets filer1’s IP address move to filer2’s interface e0a during a takeover. While using the same interface (e.g. e0a) in both controllers is not required, this symmetrical use of interfaces is good management practice.
Your suggestion of “ifconfig e0a 10.10.10.10” on filer1 means “Let interface e0a of filer1 takeover the IP address 10.10.10.10 of filer2 for the duration of the takeover”, which doesn’t sound like what you want.
Since you did mention VIF, while your example only shows bare ports, you should remember to create the ifgrp/vif on both filer1 and filer2 if you’re going to use that.

Hi all -
I have a bit of a throw-back question. I swear I've read all the docs availalbe (HA 7-mode config guide, system admin guide, network mangement guide, ethernet storage design TR) but I am still confused on how to properly configure a 7mode HA VIF failover in a situation where you only have one VIF that needs to float to a standby controller. Support tells me this is "not a common configuration" and that the solution is to have a data IP on both controllers, even if both controllers are not being used in active/active. I realize that I can do an ifconfig on each controller, with the partner option specifying the other node's IP/interface. However, this particular filer is just a large aggregate, single volume, single NFS access IP. So I don't see a point to having a data IP on the other controller...
According to the ifconfig man page ( https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_ifconfig.1.html), this is possible:
"On a node in an HA pair, a network interface performs one of these roles: ...
A standby network interface for the partner. That is, if the partner fails, the network interface works on behalf of the partner. When the node is not in takeover mode, the network interface is idle. A network interface performs this role if it does not have a local IP address but a partner IP address, which you assign by the *partner* option of the *ifconfig* command.
The node maps a partner IP address to a shared or standby interface when the node initiates a takeover operation. In takeover mode, all requests destined for the partner IP address are serviced by the shared or standby interface. Also, in partner mode, if a command takes a network interface name as an argument, enter the network interface name of the failed node. The command is executed on the shared or standby interface on the live node. Similarly, in partner mode, a command for displaying network interface information displays the network interface name of the failed node, even though the command is serviced by the shared or standby interface on the live node."
Help me think this through. This means if I want filer1 to be active and filer2 to be standby with a sinlge VIF, filer1 would have something like 'ifconfig e0a 10.10.10.10', while filer2 would have something like 'ifconfig e0a partner 10.10.10.10'?

Not really; MTU size is property of physical interface and so is set on filer2.

I suppose you could, but it's not really needed. The mtusize is set on filer1. All you are doing on filer2 is telling the interface where to land.

Specifically, I would try running the command on the command line until you get it to work with all the arguments you need want. If you define on one, you should define on the other. Once you get it, commit to /etc/rc

Add this to the rc on filer2 after your ifgrp create line:
ifconfig vif_orig_data partner vif_orig_data
So now the rc file on filer2 should look like this:
hostname filer2 ifgrp create single vif_orig_data e0b e0a ifconfig vif_orig_data partner vif_orig_data ifconfig e0M `hostname`-e0M netmask 255.255.255.0 mtusize 1500 route add default 10.10.10.254 1 routed on options dns.enable on options nis.enable off savecore
