## 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

# DeleteScsiLunState(deleteScsiLunState)

For previously detached SCSI Lun, remove the state information from host. Detach SCSI Lun marks the device where I/Os are not allowed. Host still maintains the entry of this device and its state. If a LUN is detached using detachScsiLun, ESX will not automatically attach this LUN durng a rescan or after a reboot. See DetachScsiLun. Please note: The API takes 'canonicalName' of the ScsiLun object instead of the ScsiLun.uuid.

# 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.

_this | ManagedObjectReference | A reference to the HostStorageSystem used to make the method call.

# 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 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.

# SetNFSUser(setNFSUser)

Set NFS username and password on the host. The specified password is stored encrypted at the host and overwrites any previous password configuration. This information is only needed when the host has mounted NFS volumes with security types that require user credentials for accessing data. The password is used to acquire credentials that the NFS client needs to use in order to secure NFS traffic using RPCSECGSS. The client will access files on all volumes mounted on this host (that are mounted with the relevant security type) on behalf of specified user.

At present, this API supports only file system NFSv4.1.

# UnmountForceMountedVmfsVolume(unmountForceMountedVmfsVolume)

Unmount the 'forceMounted' Vmfs volume. When a low level block copy is performed to copy or move the VMFS volume, the copied volume is unresolved. For the VMFS volume to be usable, a resolution operation is applied. As part of resolution operation, user may decide to keep the original VMFS Uuid. Once the resolution is applied, the VMFS volume is mounted on the host for its use. User can unmount the VMFS volume if it is not being used by any registered VMs.

# UnmountVffsVolume(unmountVffsVolume)

Unmount the VFFS volume. An unmounted volume cannot be used for any filesystem operation requiring I/O.

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
                           V  |
                         Unmounted Vmfs Volume

        detachScsiLun      |  ^ attachScsiLun
                           V  |
      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.

DuplicateName | Thrown if the name does not name uniqueness restrictions. Name uniqueness restrictions will vary based on the context in which this method is invoked. When this method is invoked on a host directly, no uniqueness checks will be performed on the name. When this method is invoked on a VC server, uniqueness checks will be performed on the name. The uniqueness check will ensure that the name is unique with respect to the entire VC instance.
HostConfigFault | Thrown for all other configuration failures.
InvalidName | Thrown if the name does not meet name restrictions such as an 80 character limit.
NotFound | Thrown if the device could not be found.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
