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
    .
