had 0.4.4 version of the multipath tools installed from Lars website along with
the kernel 2.6.5-7.183 kernel. The path status is never getting updated when
the path is made unavailable or available. Then we used OS sg tools to check if
we are able to get "test unit ready (tur)" responses proper as the
path checker we used is "tur". The response of "tur is proper
when it's run on "sg" devices", but it always succeeds when run
on "sd" devices. As the "tur" path checker uses
"sd" devices to check the path, we never got the path change status. <o:p></o:p></span></font></p>
