Anti affinity rules

[DanieleFiore201]

Dear guys,

there is something wrong my my anti affinity rule.

I have set up a single rule to keep 2 VMs on different servers.
There are no conflicts so far as this is the only one existing rule.

I have tested that moving one of the 2 VMs together on the same host and i would expect the other VM to be moved automatically on the other host applying the rule so far.

Nothing happened , am i doing something wrong ?

DRS is set to fully automated, vSphere 4.1

Can you help me ?

Many thanks.

Daniele

Hi Daniele,

can you manually move both VMs (maybe there are VMotion compatibility issues)?

Also can you post a screen shot of the DRS separation rule?

Dear Andreas,

thanks for your email.

I moved both VMs successfully and vMotion is ok.

Have a look on the screenshot.

thx

Please check the DRS tab of the cluster. Are there any Recommendations or Faults listed after you move both VMs to the same hosts?

No reccomendations or faults

Then I am at my wits' end ... you should open a support case with VMware.

Or anyone else?

Did you configure all the necessary settings for the rule (e.g. strict enforcement)?

Please take a look at https://www.vmware.com/pdf/vsphere4/r41/vsp_41_mscs.pdf (Chapter 5) which explains the necessary settings to keep VMs separated.
