Multipath Management

The vSphere Storage documentation includes information about using multipathing for failover and load balancing. You can manage multipathing using the vSphere Client, the esxcli command, or using the following commands. Use the HostStorageSystem.multipathStateInfo property to access the HostMultipathStateInfo data object that describes runtime information about the state of multipathing on a given host.

■	EnableMultipathPath – Enables a disabled path for a device. Use the pathname from HostMultipathStateInfoPath or HostMultipathInfoPath.

■	QueryPathSelectionPolicyOptions – Obtains the set of path-selection-policy options. These options determine the path that can be used by a device that is managed by native multipathing. A HostMultipathInfo data object identifies the devices that are managed through native multipathing.

■

QueryStorageArrayTypePolicyOptions – Obtains the set of storage-array-type policy options. These options determine the storage-array-type policies that a device that is managed by native multipathing might use. A HostMultipathInfo data object identifies the devices that are managed through native multipathing.

■	SetMultipathLunPolicy – Updates the path selection policy for a LUN. Specify the LUN using the LUN UUID from the HostMultipathInfoLogicalUnit object.

■	DisableMultipathPath – Disables an enabled path for a device. Use the pathname from HostMultipathStateInfoPath or HostMultipathInfoPath.
