When installed our NetApp was setup with e0a and eob for a virtual interface called Internal_VIF for CIFS traffic and mirror for HA failover on the other controller. e0c and e0d similar for a virtual Interface called Vmware_VIF for Vmware traffic on NFS.
In order to use iSCSI as well, VLAN's were created on e0a and e0b so that CIFS and iSCSI traffic could co-exist and route.
Int1_VIF and Int2_VIF is the CIFS traffic connected to a CISCO switch.
Int1_VIF-20 and Int2_VIF-20 which is VLAN'd on the CISCO switch to VMWare hosts for iSCSI traffic.
e0c and e0d remain for VMWare NFS traffic using storage on controller A.
The above is required for accessing storage on controller B.
Both the VMWare NFS, and Int1_VIF-20/Int2_VIF-20 iSCSI interfaces on both controllers display in OnCommand Manager correctly with HA Failover mode as Shared and the partner Interface displayed correctly (see attached).
However Int1_VIF and Int2_VIF on each controller is greyed out in properties and HA failover shows 'Dedicated' rather than Shared. The partner interface displays the correct interface wihout the IP in brackets.
Is the configuration above correct? And is OnCommand manager just displaying incorrectly? Or does the configuration need to change? How can I confirm HA failvoer is working correctly?
Until Data ONTAP 8.x it was not supported to configure both base and VLAN interfaces at the same time. May be, OCSM still does not expect it. Which Data ONTAP version do you have? Make sure to install the latest OCSM 2.0.1; if you still can reproduce it, post on System Manager community.
I am running Ontap 220.127.116.11-mode. I had OCSM 18.104.22.1687 installed. I just upgraded to the latest 22.214.171.1241 and the problem remains. However the interface is a lot faster:) System Manager Community will do.
OK I've amanged to sucessfully resolve this via command line and failover occurs correctly. I also modified for LACP, but the config works just fine for MULTI as well. Just replace the word lacp with multi.
Also make sure your clocks are near identical on each filer, use the date command to verify, otherwise takeover can mess up and copy the config of the other partner instead causing a duplication of interfaces and IP's.
options timed.enable on
options timed.proto ntp
options timed.servers pool.ntp.org <- or other time server, but has to be identical on both filers.
Check that your NTP protocol port is actually open for both filers on your firewall.
Lastly use the excellent HA config checker tool. If you have even the smallest typo in your rc and hosts files failover fails. Even upper and lowercase miss matches will casue it to fail or cause strange results.
in order to run this I had to run from a linux box (ubuntu).
Please note the above can't be done on oncommand manager at the time of writing and when you do the above it displays incorrectly in the manager as being dedicated and not shared for the Internal_VIF and is greyed out. This is a bug in the manager which I am following up with NetApp currently.
