Since: vSphere API 6.0

Managed Object Description

VimClusterVsanVcDiskManagementSystem enahnces Virtual SAN disk management part, provides Virtual SAN all flash fisk group support, exposes more detailed information of Virtual SAN disk group, helps on configure and manage Virtual SAN disk group. It deprecates APIs vim.host.VsanSystem.AddDisks and vim.host.VsanSystem.InitializeDisks, exposes vim.vsan.host.DiskMapInfoEx through API QueryDiskMappings, to present whether a disk group is all flash, and whether Virtual SAN deduplication and compression is enabled on this disk group, and deprecates vim.vsan.host.ConfigInfo.storageInfo.diskMapping exposed by vim.host.VsanSystem.config. The ManagedEntity can be accessed through MOID of vsan-disk-management-system, through Virtual SAN service at vCenter server side.

Methods

Methods defined in this Managed Object
InitializeDiskMappings, QueryDiskMappings, RetrieveAllFlashCapabilities

InitializeDiskMappings(initializeDiskMappings)

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

Required Privileges: System.Read
