vmotion issue

[piaakit]

Hi

       I have a vcenter, both esxi server i have added them by host to vcenter, & then i have two esxi5.1 Server, they are esxi A & esxi B, they have their own storage, its not sharing the same storage, & i want to move one vm machine from esxi A datastore to esxi B datastore

& the esxi hosts is using different hardware spec & brand name, but it is using intel CPU for both servers,

and i am doing below vmotion move in web client, and i get this message, any idea ?

The virtual machine requires hardware features that are unsupported or disabled on the target host:
* Carryless multiply (PCLMULQDQ) (see KB 1034926)
* SSE4.1
* SSE4.2
* AES instructions (AES-NI) (see KB 1034926)

If possible, use a cluster with Enhanced vMotion Compatibility (EVC) enabled; see KB article 1003212.

CPUID details: incompatibility at level 0x1 register 'ecx'.
Host bits: 0000:0010:1001:1000:0010:0010:0000:0011
Required:  x000:x00x:00x0:0xx0:xxx0:xx1x:xx0x:xx01

the esxi hosts is using different hardware spec & brand name, but it is using intel CPU for both servers

Both the host might be having a CPU from different family set with different features. So you have to Enable Enhanced vMotion Compatibility (EVC) on the cluster and add both the host to the cluster.

Check the model of the CPU's and use the below KB to find the suitable generation for the CPU

Enhanced vMotion Compatibility (EVC) processor support (1003212)

EVC and CPU Compatibility FAQ

so that the two esxi hosts not using the same storage is workable for vmotion ?

[BenLoveday]

Correct, as of vSphere 5.1 a vmotion can be performed across hosts that don't have shared storage, however as aravinds3107 mentioned there are other requirements/limitations that need to be factored in. Check the EVC configuration on your cluster first as this might be the problem.

in order to do this i have to add the two esxi hosts in vcenter ->new cluster ?  and then choose "turn on vsphere DRS" in my case ? or "Turn on vsphere HA" ?

Not entirely correct you will have to implement the VMware vSphere Storage Appliance - this allow you to share local storage between esxi hosts allowinf to implement vMotion and DRS without the use of SAN or NAS storage.

For more information see vSphere Storage Appliance - Shared Storage for Everyone

[dave330i]

No. You need to turn on EVC. Assume ESXi A is Westmere chipset while ESXi B is Nehalem. You'll need to "downgrade" ESXi A to Nehalem capabilities. All the VMs running on ESXi A will have to be powered off while your "downgrading" ESXi A.

so that in my case i need to deploy "vSphere Storage Appliance" first to allow local storage aware of each other, before starting vsphere storage appliance, i need to add cluster of the two esxi hosts in v center and DRS them, also i need to turn on EVC , and of coz both esxi server cpu is capailities as well , correct ?

I would install the vSphere Storage Appliance on each host first - then create the cluster - enabling the EVC when you create the cluster -

my two esxi server cpu is using intel Xeon E5645 & Xeon E5620 , two cpu are Westmere-EP , vmotion requirement should be meet right ?

Hi,

my two esxi server cpu is using intel Xeon E5645 & Xeon E5620 , two cpu are Westmere-EP , vmotion requirement should be meet right ?

Yes, the CPU models you've listed are in the same family so no problem.

i need to install vSphere Storage Appliance for vmotion ? and my 2 esxi server is not shared the same storage

[julienvarela]

Yes you need to install VSA if you want to use vmotion fonctionnality with local storage. VSA will create a unified shared storage accross your ESX.

[piaakit]

IS there any documentation show how to use VSA ? I need to add cluster in vcenter for my two esxi first ?

[julienvarela]

Yes here : http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-storage-appliance-51-install-a... and yes you need to create a cluster and add your hosts.

when i try to click on register trial verison of VSA, the link brought me to the following,i need to download and install this or VSA Automated Installer ? i also download VSA Automated Installer, it said my trial version is not valid during the VSA Automated Installer installation, can anyone tell me the correct install source to download  ? Thx

VMware vCenter Operations Management Suite 5.7 (supports VMware vCenter Server 5.1 only)

[piaakit]

can i install VSA if my esxi already has vm host running, i read some post saying that before install VSA, the esxi server must be clean without any vm host created, is that true ?

[julienvarela]

Hi,

No you can install your VSA on a running environnement, but it is a little more complicated. You need to create a new datastore (Without the full size or your local disk), Then migrate your VM on it. After Your can add to your VSA volume the space now available (Delete your datastore). But for extend your VSA volume a reboot is required.

VSA Automated Installer is the installer i need for VSA ? but when i click the link to apply trial on VSA, it shows me the link of VMware vCenter Operations Management Suite 5.7, also it shows me the trial key for it, after i downloaded VSA, and when i tried to install, i insert the trial key, it said is invalid, do i need to install something else first ?

[julienvarela]

Hi,

No, it's because you are using the license key for VMwere vCenter Operations Management Suite 5.7 Not for VSA. That's why.

You can install your VSA without insert a license key, your VSA will be in evaluate mode for 60days.

Julien.
