Remove APA Configuration

Hi,

We have a server that seems to have some very strange configuration done on it. It has 2 physical NIC's and rather than both be aggregated into LAN900 we have 1 in LAN900 and 1 in LAN901? (See Below)
root@uk205:/etc/rc.config.d> nwmgr --get

Name/ Interface Station Sub- Interface Related
ClassInstance State Address system Type Interface
============== ========= ============== ======== ============== =========
lan0 UP 0x00215ADE6C5A iether 1000Base-T lan901
lan1 UP 0x00215ADE6C5B iether 1000Base-T lan900
lan900 UP 0x00215ADE6C5B hp_apa hp_apa
lan901 UP 0x00215ADE6C5A hp_apa hp_apa
lan902 DOWN 0x000000000000 hp_apa hp_apa
lan903 DOWN 0x000000000000 hp_apa hp_apa
lan904 DOWN 0x000000000000 hp_apa hp_apa

My question is this. We have been asked to remove the aggregation as we are trying to figure out some connectivity issues and want to revert back to running network traffic via 1 single NIC to start with. But how do i go about removing the aggregation configuration?

Can i just use the command nwmgr -d -A links=0 -I 900 -S apa for example to remove each port and then stop the daemon with /sbin/init.d/hpapa stop?

Would that work?

You can use the nwmgr command on LAN or RDMA interfaces to:

â ¢Reset the interface or its statistics

Reset the VLAN interface.
nwmgr -r -c lan [--st][--sc]

Resetting the interfaces would not take both physical LANS out of the APA configuration would it??

That is what i need to do.

Sorted this after doing some testing.
