Is there a cure to ESXi and HP EVA Controller Ping Pong?

Is there a cure to ESXi and HP EVA Controller Ping Pong?

Hi People,


We have:


EVA 6400

SATP, PSP, ALUA, & Round Robin configured IOPS=1 etc  as per HP EVA / vSphere Best Practices.

Virtual Connect & Flex-10.


Each time we add a new  blade server [vSphere ESXi 4.1 Update 1 built from HP DVD] we suffer from controller ping pong where it forces the controllers to switch masters and overloads a preferred path. This then causes major performance problems with ESXi hosts and their hosted VMs.


We have to resort to manually changing master controllers for each LUN until it is balanced again, whilst Command View and vCenter are almost hanging.

How is your zoning set up?


I've seen the controllers ping-pong or "flap" when vdisks aren't presented / un-presented properly.


At what point do you start to see this happening?
