We have procurve 8212 backbone and 3 Vmware ESXI-5 server in cluster mode, there is VMOTION function in Vmware, this function giving us the ability to transfer vm’s between hosts, for HA and LNB.
The problem is probably in our backbone arp table, because for example, we have linux vm on server01, server01 connected to the backbone in port E10, then VMware moves the VM to server02 and then the linux VM is now in port E12.
The process of vmotion and the VM transformation should take at MAX 1 seconds! We should lose 1 ping…in the reality it takes at least 10 second..
60% of the world working with VMware and al lot of them working with HP switches, It can be so long to make VMOTION transfer, the VM will disconcert from the storage and the users also..
If im doing the VMOTION transfer and Im writing “clear arp” in my backbone, the process goes fine! In 1 second. But without my interruption it take long time than expected…
I fond online this command “ip arp-mcast-replies” and I have entered it to my backbone, and it does helped but 50%..some time it take 1 second and some time 10 second..
Someone can help me with that?
I also changed the arp and mac tale age time to 60 seconds(the minimum..)
I am at a loss, please advise Image may be NSFW.
Clik here to view.
Thanks!!
