Re: Adding a virtual disk on SCSI controller with physical/virtual sharing fails

This behaviour is seen when VMDK is created using perl script and SCSI controller bus sharing is either physical or virtual.  And this is happening because, using perl script if we create a virutal disk it is getting created as "Thick Provisioned Lazy zeroed" which is not being able to share with other VMs. But if we create disk "Thick Provisioned Eager zeroed" disk manually then it is getting shared properly.

Is there any API or method with which we can convert disk provision from 'Lazy zeroed' to 'Eager zeroed' ? We can able to convert it manually once we created it, using 'vmkfstools', but I am creating disks and sharing it with multiple VMs at the same time.

Please let me know how to convert disk from thick to thin or from 'lazy zeroed' to 'eager zeroed'.

Thanks
