There are no available paths to
the pseudo-LUN. The device has
gone into total failure and will be
removed.
A PnP request for QueryRemove
was rejected because the device
is in the paging, hiber, or crash
dump path state.
An issued request from the
pseudo-LUN's queue failed. This
always occurs when the device is
in the process of being removed.
One of the following events
occurred during failover: MPIO's
call to the DSMs InvalidatePath
failed; DSM did not return a new
path; DSM did not return a path
when MPIO called the LBGetPath
routine.
MPIO is unable to find an

MPIO received a DSMNotification
call, but is unable to map the
DSMID to a device.
DSM called DSMSendRequest to
have MPIO send a request on its
behalf, but MPIO is unable to find
