Description
for devices that use the group_by_prio path grouping policy,
which means that all the paths in a path group will always have the
same priority.
If set to uniform, all path weights are equal. The default value is
uniform.
A numeric value for this attribute specifies the number of times
the system should attempt to use a failed path before disabling
queueing.
A value of fail indicates immediate failure, without queuing.
A value of queue indicates that queuing should not stop until the
path is fixed.
The default value is (null).
(RHEL 4.7 and later) If set to yes, the multipathd daemon will
disable queueing when the last path to a device has been deleted.
The default value is no.
