Delete Redundant Cluster LIF

[Dlaumor]

Hi everyone,

I installed Simulate ONTAP 8.3 on vSphere 5.5

I have 2 virtual machines with these network port:

cluster2::> net port show
  (network port show)
                                                             Speed (Mbps)

cluster2::> ifgrp show

         a0a        ip           02:0c:29:8b:ce:13 full    e0c, e0d

I would like to delete the ifgroup

cluster2::> ifgrp delete -node cluster2-01 -ifgrp a0a

Error: command failed: Interface group remove failed (Port already has a lif bound. ). Some member ports may have already been
       removed. To verify port membership, use the "network port ifgrp show" command.

 However, I can't migrate the only LIF on this ifgroup because it's the node-mgmt LIF

cluster2::> network interface show
            Logical    Status     Network            Current       Current Is
Vserver     Interface  Admin/Oper Address/Mask       Node          Port    Home
----------- ---------- ---------- ------------------ ------------- ------- ----
...

            cluster2-01_mgmt1
                         up/up    10.0.52.121/24     cluster2-01   a0a     true 
...

 Do you have any idea to delete this ifgroup?

Thanks in advance.

Hi,

can you try removing the ports from the ifgrp, and then try to delete the ifgrp?

ifgrp remove-port -node nodename -ifgrp a0a -port x0X

Hi,

Thanks for your answer. Unfortunally, it doesn't work.

cluster2::*> ifgrp remove-port -node cluster2-01 -ifgrp a0a -port e0c

Error: command failed: Port already has a lif bound.

cluster2::*> ifgrp remove-port -node cluster2-01 -ifgrp a0a -port e0d

Error: command failed: Port already has a lif bound.

I confirm the only LIF on my a0a port is the node-mgmt. I migrated the cluster LIF on the other node. I also set the home port of every LIF to the second node to avoid problems

cluster2::*> net int show
  (network interface show)
            Logical    Status     Network            Current       Current Is

Can you try migrating the lif to a different port from e0c 

network interface migrate -vserver <original_vserver_name> -lif <original_lif_name> -dest-node <migrate_to_node> -dest-port <migrate_to_port>

You might also get a message indicating that the failover policy/group is still assigned to the port you wish to modify. If so issue of the following:

network interface modify -vserver <original_vserver_name> -lif <original_lif_name> -failover-group system-defined

[Dlaumor]

The LIF is not on e0c but on a0a.

The problem is only on the first node (cluster2-01)

[deepuj]

where you successfull in removing the members (e0c,e0d) from the ifgroup a0a?
I saw the error message when you try it, you may have to migrate the LIF's hosted on these interfaces and remove it from the ifgrp, and then try to delete the ifgrp

Thanks
