Hi

 

I am getting below error while executing Block_Zero_Disk.

Please note:

 

1. I went through some of the previous community threads and tried creating a 2T VMFS3 lun (max supported?) which I upgraded to a VMFS5.54 on ESX5.0 U2. This didn't help as the test requires > 2.1TB LUN.

 

2. I ran the following cmd to check if VAAI is supported wrt our storage array:

 

 

esxcli storage core device vaai status get | more

 

t10.CloudByt6_______________b6b797a02D4a482D32832Da7d12D1a0d93d6

   VAAI Plugin Name:

   ATS Status: supported

   Clone Status: unsupported

   Zero Status: supported

   Delete Status: unsupported

So I guess vaai is partly supported.
Question:
Does clone status Unsupported imply that vmdk cloning and/or vmdk clone compares would FAIL?  The vmware test appears to be using a tool called diskLibCertTool - I am not sure what this does, but from a manual scan the actual vmdk file and the cloned one were the same in size.
Thanks.
