AddDisks_Task(addDisks)

Add the set of given disks for use by the VSAN service on this host. Users may use this API to manually add disks for use by VSAN, without specifying an explicit DiskMapping, when the VSAN service not configured to automatically claim storage. Any ineligible disk in the set of given disks and disks which would have exceeded the capacity will be ignored and will not be published in returned result.

Mount a DiskMapping if the specified disk belongs to the unmounted mapping and is of type DiskMapping#ssd.

Upon successful completion of the returned Task, its result field will be populated with a VsanHostDiskMapResult[] and caller must inspect VsanHostDiskMapResult[] to check result for individual DiskMapping.

This method may not be used to remove the last DiskMapping#nonSsd from any given DiskMapping. Removal of the last DiskMapping#nonSsd can be accomplished by using RemoveDiskMapping_Task.

Upon successful completion of the returned Task, its result field will be populated with a VsanHostDiskResult[]. Sets DiskIsLastRemainingNonSSD fault in returned task if specified disk is the last DiskMapping#nonSsd member of DiskMapping.

UnmountDiskMapping_Task(unmountDiskMapping)

Unmount the mounted DiskMapping. An unmounted volume cannot be used for any VSAN operations. In contrast to RemoveDiskMapping_Task, this operation does not destroy or alter VSAN data on the disks. AddDisks_Task and InitializeDisks_Task can be used to re-mount the diskMapping.

In case of shared-SAS, where diskMappings are visible to more than one VSAN hosts, Users may use this API to manually unmount and re-mount diskMappings.

Upon successful completion of the returned Task, its result field will be populated with VsanHostDiskMapResult[]. If any errors are encountered, the returned field will instead contain populated error information.
