Hello,
i have some problems with EVC which i do not understand. I recently have added a new IBM System X 3650 M4 server with Intel Xeon E5-2650 v2 Cpu's. The other 2 Servers are an IBM Server with Intel Xeon E5540 Cpu's and a Dell server with E5430 CPUs. Now when i add the new machine to the cluster and enable EVC it will do so and confirms that EVC is running in Intel® "Penryn" Generation (Xeon® 45nm Core™2) as this is the first one that works for all 3.
The problem which now occurs is that i can migrate a machine to the new host but not back. When i try to migrate a running machine back it always says that the Host CPU is not compatible and that the following functions differ: PCLMULQDQ, SSE4.2, AES-NI and that i should use a Cluster with enabled EVC. But i have EVC enabled for this cluster. How can i resolve this issue, anyone got an idea?
Thx in advance
René
Can you try disabling "AES" or "Advanced Encryption Standard" from BIOS as mentioned in the KB below
VMware KB: vMotion/EVC incompatibility issues due to AES/PCLMULQDQ
Refer :VMware KB: EVC and CPU Compatibility FAQ & Enhanced vMotion Compatibility - frankdenneman.nl
These resources would increase your EVC understanding greatly.
Trying to do exactly this as i found alot of references to this when using systems newer then System X 3650 M3. Thing is the ASU tool gives me no option to disable it like IBM Supports suggests ( asu64 set UEFI.AesEnable Disable )
asu64 show gives me only those options:
c:\Users\r.toller\Downloads>asu64 show uEFI --host 10.1.XX.XX --user XXX --password XXX

I couldn't find IBM System X 3650 M4 server with Intel Xeon E5-2650 in the support list of VMware compatibility list [Server with EVC feature]
VMware Compatibility Guide: System Search
VMware Compatibility Guide: System Search
Isnt that what i shall be looking for? Shows up for me there, 2nd last entry. Might be that i have to update my cluster to atleast 5.1 from 5.0.0. Still dont understand why ASU does not give me the UEFI commands though.
Your are right you need to upgrade it to 5.1 and for UEFI commands for ASU you need to contact IBM support team.
hi
I have the same problem. I can not disable AES. You've had a response from the IBM support?
