Hello there.

I'm managing CloudPlatform(Cloudstack) 3.0.2 with XenServer 6.0.2.

I set the global configuration xen.setup.multipath as false because we didn't have a plan to use XenServer ISCSI Multi-path function at that time.

But these days we are considering the use of XenServer ISCSI Multi-path function with Hitachi AMS2500 to increase the performance.

We have 2 zones, 3 PODs(16 XenServer each) in each zone and we are planning to add another PODs to each zone with XenServers enabled the ISCSI Multi-path function.

I have 2 questions.
1. Do I have to change xen.setup.multipath parameter to enable Xenserver ISCSI Multi-path?
2. Are there any possible side effects that affect to the present 3 PODs?

Please let me know.
Thank you in advance.
