![DataONTAP.Virtualization.CheckLUNAlignment](/images/Tasks.png) | Data ONTAP Virtualization: Check LUN Alignment Status | This rule checks the LUN alignment. For optimal performance, the file system on this LUN and the storage array should be in proper alignment. | DataONTAP.Virtualization.CheckLUNAlignment | DataONTAP.Virtualization.HyperV.LUN | Internal | Custom | True | False | 900 |
![DataONTAP.Virtualization.CheckVHDAlignment](/images/Tasks.png) | Data ONTAP Virtualization: Check VHD Alignment Status |
This task checks the alignment of Virtual Hard Disks. For optimal performance, the file system of the VHD and the storage array should be in proper alignment.
NOTE: For large number of VHDs, please use the "Data ONTAP Virtualization: Check Host Alignment Status" in the Hyper-V Hosts view for performance reasons.

![DataONTAP.Virtualization.Discovery](/images/Tasks.png) | Data ONTAP: Run Virtualization Discovery task | This is the discovery task for all Hyper-V Hosts, Hyper-V LUNs, Hyper-V Virtual Hard Disks and Hyper-V VMs using Data ONTAP storage systems. This rule contacts each Hyper-V Host that uses Data ONTAP storage resources and discovers all of its logical storage elements. | DataONTAP.Virtualization.Discovery | Microsoft.SystemCenter.ManagementServer | Internal | Custom | True | False | 10800 |
![DataONTAP.Virtualization.Host.CheckLUNAlignment](/images/Tasks.png) | Data ONTAP Virtualization: Check Host LUN Alignment Status | This task checks the LUN alignment for all LUNs mapped to the selected Hyper-V hosts. For optimal performance, the file system on this LUN and the storage array should be in proper alignment. | DataONTAP.Virtualization.Host.CheckLUNAlignment | DataONTAP.Virtualization.HyperV.Host | Internal | Custom | True | False | 900 |
![DataONTAP.Virtualization.Host.CheckVHDAlignment](/images/Tasks.png) | Data ONTAP Virtualization: Check Host VHD Alignment Status | This task checks the alignment of all Virtual Hard Disks on the selected Hyper-V hosts. For optimal performance, the file system of the VHD and the storage array should be in proper alignment. | DataONTAP.Virtualization.Host.CheckVHDAlignment | DataONTAP.Virtualization.HyperV.Host | Internal | Custom | True | False | 5400 |
