How do I enable and disable the ODX function?

Hi Geek,

1. Start the Windows PowerShell on the host.

a. Run the get-itemproperty HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem command to query whether the ODX function is enabled on the host.Check the value of FilterSupportedFeaturesMode. Value 0 indicates that the ODX function is enabled. Value 1 indicates that the ODX function is disabled.

b. Enable or disable the ODX function.

Run the set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -name "FilterSupportedFeaturesMode" -Value 0 command to enable the ODX function on the host.

Run the set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -name "FilterSupportedFeaturesMode" -Value 1 command to disable the ODX function on the host.

2. Enable the ODX function on the storage device.

a. Run the following command to enable or disable the ODX function:

Run the change odx odx_enabled enabled=yes command to enable the ODX function on the storage device.

Run the change odx odx_enabled enabled=no command to disable the ODX function on the storage device.

b. Restart the storage device (this operation stops all services running on the storage device).

c. After the device is powered on, uninstall physical disks and virtual disks generated by the multipathing software in the disk manager for mapped LUNs and rescan the disks (that is, operate the disks as new disks after clearing residual disk information).

Thanks.
