Problems with EVC

[StukaRT]

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

[vThinkBeyondVM]

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

[StukaRT]

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.

[ScreamingSilenc]

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?
