Long time since my last post, Christmas you know ;-) BTW Merry Christmas and Happy New Year to all of you.
During this weeks I’ve been configuring APA failover groups in some of my blades and I thought It would be interesting to post how I did it. There are two ways to configure APA in HP-UX 11.31, through the SMH and with the nwmgr command. The screenshots are in Spanish since this is how the SMH of my servers are configured.
Log into the server SMH and go to Tools -> Network Interface Configuration -> Auto Port Aggregation.
Now click on Create Failover Group and select the interfaces to add, you can also configure the advanced parameters for the group, when you’re done click OK to finish the operation.
Now in the main page of APA the new group will be shown instead of the LAN interfaces the are part of the group:
And this is it, the new APA Failover Group is configured and completely transparent to the users. From this point you can show the information about the newly created APA interface.
The nwmgr command has replaced the old lanscan, lanadmin and linkloop commands in 11.31. I have to say that I prefer this way instead of the SMH one to do any APA or LAN related tasks. SMH require TCP/2301 and TCP/2381 ports to be open and accessible and this is not always possible mainly because security policies but to use nwmgr you only need access to the server through SSH.
To begin show the current configuration:
Now proceed with the creation of the new failover group:
Specific advanced parameters can also be set, in the example I used the parameters rapid_arp_count and poll_interval:
To show the new config:
If you want to delete an existent failover group:
Or if you just want to remove a interface from the group:
And we are finished, I still have 11.23 systems and I want APA for them too so I will post how to do it with the lanadmin command.
