Will the Enginuity epack also fix the issue in emc252367?

Stanley Merkx

The primus article mentioned is not available for customers on powerlink. My ASR pointed me to a different one: emc263675.

Do you have any more info on the Enginuity service release scheduled for 3/30??

Drew Tonnesen

The VAAIs can be turned on and off dynamically through the vSphere Client, even during operations that take advantage of them. There will be no disruption in an ongoing operation as it switches between either using the API or not. Ergo, no reboot of the ESX host is required.

Craig Dodson

Now, what about the ESX crash-causing bug between PowerPath and VAAI? Let's get some coverage of that issue please. It's hit us and I understand there are more EMC customers who have experienced this. The irony here is that we spent *more* to get PowerPath, and now we have to turn off VAAI because of this bug!

Chad Sakac

@Craig - thank you for being a customer. This issue has just popped on my radar, and the crew is digging deep.

It's too early to point to root cause, but looks like it might be a very specific condition with a given HBA (but widespread). Regardless, we are responsible for resolution to your satisfaction.

Question - do you mind emailing me your specific SR #?

Keith Kearnan

The Enginuity epack will not fix the issue in emc252367.

EMC, VMware and Emulex are working together on this issue. It is not considered to be a PowerPath bug. At this time the cause is unknown. Our efforts are being hampered by the inability to reproduce this in house. Two customers that had seen the problem have been working with us but they have not seen the issue since.


Keep on writing, great job!
