Hi All,
I have a requirement where in I have to disable and then enable ATS on a vmfs5 datastore with active I/O. Since it has to happen on a per lun basis, I have ruled out the possibility of using advanced settings /VMFS3/HardwareAcceleratedLocking
#esxcli system settings advanced set --int-value 0 --option /VMFS3/HardwareAcceleratedLocking
I know below command will help me to set ATS on a per lun basis but it throws out error when I use it on a vmfs5 partition with active I/O. Is there any way to get this done.
On a VMware ESXi 5.0.0 build-1311175, I get below error.
~ # vmkfstools --configATSOnly 1 /vmfs/devices/disks/naa.600a098038425863515d426b51596551:1 --force
Checking if all devices backing VMFS '/vmfs/volumes/miio1' are capable of ATS. This may take a few seconds...
VMFS '/vmfs/volumes/miio1' cannot be upgraded to ATS capability as all devices backing it are not ATS capable
Error: Operation not supported
On a VMware ESXi 5.1.0 build-1065491, I get below error.
