## Managed Object Description

This managed object gets and sets configuration information about the host's storage subsystem. The properties and operations are used to configure the host to make storage available for virtual machines. This object contains properties that are specific to ESX Server and general to both the ESX Server system and the hosted architecture.

Properties

Name | Type | Description
--- | --- | ---
fileSystemVolumeInfo | HostFileSystemVolumeInfo | File system volume information for the host. See the FileSystemVolumeInfo data object type for more information.
multipathStateInfo* | HostMultipathStateInfo | Runtime information about the state of a multipath path. A null value will be returned if path state information is not available for this system. In systems prior to the plug-store architecture, the state of a path may be accessible on the HostMultipathInfo data object of the StorageDeviceInfo property. Since vSphere API 4.0
storageDeviceInfo* | HostStorageDeviceInfo | Host storage information up to the device level.
systemFile* | xsd:string[] | Datastore paths of files used by the host system on mounted volumes, for instance, the COS vmdk file of the host. For information on datastore paths, see Datastore. Since vSphere API 4.1

Please note: The API takes 'canonicalName' of the ScsiLun object instead of the ScsiLun.uuid.

# QueryStorageArrayTypePolicyOptions(queryStorageArrayTypePolicyOptions)

Queries the set of storage array type policy options. The set of policy options indicates what storage array type policies can be used by a device managed by native multipathing. Devices managed through native multipathing are described in the HostMultipathInfo data object.

Filtering capabilities are not currently present but may be added in the future.

# ResolveMultipleUnresolvedVmfsVolumes(resolveMultipleUnresolvedVmfsVolumes)

Resignature or 'Force Mount' list of unbound VMFS volumes. To safely enable sharing of the volume across hosts, a VMFS volume is bound to its underlying block device storage. When a low level block copy is performed to copy or move the VMFS volume, the copied volume will be unbound. In order for the VMFS volume to be usable, a resolution operation is needed to determine whether the VMFS volume should be treated as a new volume or not and what extents compose that volume in the event there is more than one unbound volume.

Resignature results in a new VMFS volume on the host. Operations performed at the StorageSystem interface apply only to a specific host. Hence, callers of this method are responsible for issuing rescan operations to detect the new VMFS volume on other hosts. Alternatively, callers that want VirtualCenter to handle rescanning the necessary hosts should use the DatastoreSystem interface.

When user wants to keep the original Vmfs Uuid and mount it on the host, set the 'resolutionSpec.uuidResolution' to 'forceMounted' This is per-host operation. It will return an array of ResolutionResult describing success or failure associated with each specification.

# ResolveMultipleUnresolvedVmfsVolumesEx_Task(resolveMultipleUnresolvedVmfsVolumesEx)

Resignature or 'Force Mount' list of unbound VMFS volumes.

To safely enable sharing of the volume across hosts, a VMFS volume is bound to its underlying block device storage. When a low level block copy is performed to copy or move the VMFS volume, the copied volume will be unbound. In order for the VMFS volume to be usable, a resolution operation is needed to determine whether the VMFS volume should be treated as a new volume or not and what extents compose that volume in the event there is more than one unbound volume.

Resignature results in a new VMFS volume on the host. Operations performed at the HostStorageSystem interface apply only to a specific host. Hence, callers of this method are responsible for issuing rescan operations to detect the new VMFS volume on other hosts. Alternatively, callers that want VirtualCenter to handle rescanning the necessary hosts should use the HostDatastoreSystem interface.

When user wants to keep the original VMFS UUID and mount it on the host, set the resolutionSpec.uuidResolution (uuidResolution) to vim.host.UnresolvedVmfsResolutionSpec.VmfsUuidResolution#forceMount. This is per-host operation.

It will return an array of HostUnresolvedVmfsResolutionResult describing success or failure associated with each specification.

This method behaves the same as ResolveMultipleUnresolvedVmfsVolumes except that it returns a task to support monitoring the operation. This is important for operations with large number of unresolved volumes which may take potentially dozens of minutes to complete.

# UnmountVffsVolume(unmountVffsVolume)

Unmount the VFFS volume. An unmounted volume cannot be used for any filesystem operation requiring I/O. In contrast to removal, this operation does not destroy or alter partitions on which VFFS volumes reside. The mountState will be persisted across filesystem rescans and host reboots. See MountVffsVolume.

unmountVffsVolume is part of the Unmount / Detach workflow used when a device will be permanently removed. See also DetachScsiLun.

# UnmountVmfsVolume(unmountVmfsVolume)

Unmount the Vmfs volume. An unmounted volume cannot be used for any filesystem operation requiring I/O. In contrast to removal, this operation does not destroy or alter partitions on which vmfs volumes reside. The mountState will be persisted across filesystem rescans and host reboots. See MountVmfsVolume.

unmountVmfsVolume is part of the Unmount / Detach workflow used when a device will be permanently removed.

                         Mounted Vmfs Volume
        unmountVmfsVolume  |  ^ mountVmfsVolume

      Detached Scsi Device (does not honor I/O)

It is safe to unprovision a Lun from the Storage array *only* after a Scsi device is detached.

The best practice for decommisioning a Lun would be to find out the set of subsystems that a Lun is being used for. Many of the systems are listed as exceptions in the function documentation.

One typical workflow could be:

- Find out if the device is used as a Vmfs Extent. (See VmfsVolume.Extent API)
- Unmount the Vmfs Volume.
- Find out if device is used by the Diagnostic system (See Diagnostic System API).
- Deactivate the diagnostic system, if it is being used.
- Find out if this device is used to back a VM's RDM (See VirtualMachine API).
- Remove this device from the VM.
- Detach the Scsi device.
- On success, it is safe to decommision the Lun at this point.
