Managed Object Description

VimClusterVsanVcDiskManagementSystem enhances vSAN disk management part, provides vSAN all flash disk group support, exposes more detailed information of vSAN disk group, helps on configure and manage vSAN disk group.
It deprecates APIs AddDisks_Task and InitializeDisks_Task, exposes VimVsanHostDiskMapInfoEx through API QueryDiskMappings, to present whether a disk group is all flash, and whether deduplication and compression is enabled on this disk group, and deprecates diskMapping exposed by Config.
The ManagedEntity can be accessed through MOID of vsan-disk-management-system, through vSAN service at vCenter server side.

Methods

Methods defined in this Managed Object
InitializeDiskMappings, QueryClusterDataEfficiencyCapacityState, QueryDiskMappings, RebuildDiskMapping, RetrieveAllFlashCapabilities

InitializeDiskMappings(initializeDiskMappings)

This API is used to create new vSAN disk groups or attach more disks into existing vSAN disk group on specified host. It deprecates APIs AddDisks_Task and InitializeDisks_Task, to support creating both hybrid and all flash disk group. Scsi disks eligible for vSAN service, could be retrieved through API QueryDisksForVsan.

RebuildDiskMapping(rebuildDiskMapping)

This API is used to rebuild an existing vSAN disk mapping on the specified host. Rebuild disk mapping is done in two steps: 1. remove the existing disk mapping with user specified data evacuation mode; 2. re-create a new disk mapping with the same set of disks. Removal of a disk mapping may cause data movement so a disk data evacuation resource check vim.vsan.VsanResourceCheckSystem#PerformResourceCheck will be done before removing the disk mapping.
