You need to enable it on your switches if you haven't done so already.

You also need to enable flow control on the nic's when they are *not* bonded. If they are bonded, you need to break the bond, enable flow control, then rebond the nic's.

When you have a NIC Bonded on a P4000 node, what happens when you break the bond and then re-bond? Storage should still be available, right?

Re: Nic Flow control issus - Lefthand

If you have two storage nodes and the volumes are network RAID 10, you will only see a 1 or 2 second blip in the connection. Be aware that the storage nodes will need to resync the volumes so you need to wait for that to complete before you recreate the bond. If you don't wait, the LUNs will drop.

Re: Nic Flow control issus - Lefthand

I have same problem - I'm not able to set Flow control to "ON". When i set it "ON", after couple of seconds of "thinking" all seems to be OK, but parameter is still "OFF".
This is truth on all nodes under SANiQ 9.0.00.3561.0 ...

Hello,

you have to break the NIC bonding. Then you will be able to enable flow control.

Re: Nic Flow control issus - Lefthand

I have also encountered this issue. I have broken the bond, made sure that any replication is finished (none in my case) and the changed Flow Control to ON. It looks like it applies but when it goes back it says that it is OFF. We are using software revision 9.0.00.3561.0. I have also verified that the Network Admin has turned on Flow Control on the switch side.

Re: Nic Flow control issus - Lefthand

If I remember correctly, I ran in to this as well. You may have to make the 2nd NIC active, and give it a valid IP address before the FLOW controls would "stick"..

Then when you recreate the bond it will consolidate the NICs to use a single IP address

Re: Nic Flow control issus - Lefthand

Please restart the Node and check if the setting changes.

Enable flow control on individual nics and then create a bond.
Flow control will show as off on a bond even though it is working.

Yes. Setting the second NIC to active as well as setting it to an IP (or set it to use DHCP even if you don't have a DHCP server for that subnet) and then setting to active worked like a charm. Thanks for the help..
