REBOOT BAD HOME PORT -cluster and NFS-

FAS2554

Hello everybody,

 

I have the following problem every time I restart NetApp:

Because of the false "is Home" the vm stored inside are not communicating and I don't have access, so I always use the migrate command to fix it or I enter the web interface to change it to True.

 

And there are times when the current port is changed in the cluster or in the NFS.

 

So I would like to know if there is a way to fix those paranormal changes (since it happens very rarely). Is there a boot configuration file or something like that so that it always loads the right configuration?

Thank you very much and best regards.

Hi,

 

Probably, the auto-revert property is set to 'false', I am guessing, bydefault it is false for 'data LIFs'.

 

First verify:
::> network interface show -vserver vserver_name -fields auto-revert

 

If it's set to false, make it 'true'.
::> network interface modify -vserver vserver_name -lif lif_name -auto-revert true

 

With this setting, next time when the  Data LIFs failed-over, they will automatically revert to home-port once the Home-port is operational/status-admin up.

 

Thanks!

I check it:


FNC FNC-01_mgmt1 true
FNC FNC-02_mgmt1 true
FNC cluster_mgmt false

 

NFS01 NFS01_lif false
NFS01 NFS01_nfs_lif1 false

 


NFS02 NFS02_lif false
NFS02 NFS02_nfs_lif1 false

 

Would you recommend me to put everything to True?

 

(With that every reboot all things will go to their place, isn´t it?)

 

Thanks for your help!

Ontapforrum

Yes, please.

With that every reboot all things will go to their place, isn´t it?  yes, that's correct.

You're welcome.

I have this issue with the -auto-revert true in NFS01 and NFS02 lifs:

 

There are no entries matching your query

 

I don´t know why :s because the cluster_mgmt lif was changed correctly

Ontapforrum

What is the current output of : network interface show command ?

All the ports looks like are at 'Home', so that's good.

 

Also, I noticed, the Ports in your first screenshot was showing as 'a0s', probably that's why it said 'There are no entries...'. 

 

e0*, is what I would expect.

The first screen was from the day that I rebooted the NetApp (then I could solved using the migrate and the web interface client).

 

But as you told me, for prevent that issues every reboot I tried to apply the -lif auto-revert but it doesn´t works in NFS01 and NFS02.

Ontapforrum

What is the output of this command;

network port show

network port show -port  a0s -instance

Kindly  give the  output of :

::> network port show

::> network interface show -vserver NFS01 -fields home-node,home-port,curr-node,curr-port

::> network interface show -vserver NFS02 -fields home-node,home-port,curr-node,curr-port

FAS2554

Sorry (the e0s is e0a, because the first screen was taken from other NetApp with the same configuration)

 

Take the outputs:

Looks like you have under-lines issues (vifmgr/Node) and therefore when the LIF fails-over it is not reachable. Ideally, even if the LIFs fail-over, they should be reachable. However, if you want LIFs to go back to its home-port then auto-revert is the property that will turn on.

 

I see the issue in the output you shared:

Warning: Unable to list entries for vifmgr on node "FNC-01": RPC: Port Mapper failure. Therefore, it's only listing ports for Node FNC-02. Perhaps, that's why all your LIFs are attached to this Node.

 

Try to check:
::> set adv
Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.
Do you want to continue? {y|n}: y

::*> cluster ring show -unitname vifmgr

 

I would request you to log a ticket with NetApp Phone support.

 

Thanks!

FAS2554

Ok,

I´ll investigate and check

 

Thanks for your help!!

Ontapforrum

Thanks and good luck. Feel free to call NetApp phone support to sort this out.

My only thought is that it could be a broadcast domain/LIF failover group configuration.

I'd check those commands and see if you can make some headway. Without knowing your config it's hard to dig further. A case definitely isn't a bad option.

FAS2554

This current output has the migrate applied 2 weeks ago (that´s why the configuration are in his place with the trues and correctly current ports).

FAS2554

Perfect!

 

Tomorrow I´ll let you know the results 🙂

 

Thanks again!!!
