<br>
<br><tt><font size=2>I need to use OpenSM to work with both managed and
unmanaged switches. I have only a single switch in a single subnet. If
it detects that there's already a Master SM in the subnet, the OpenSM will
elect to be the slave one and wouldn't affect the work of the managed switch.
Otherwise it will work as the Master. Does current version of OpenSM have
this functionality?</font></tt>

It shouldn't be the case if there's only a single switch in a single subnet.
Correct?</font></tt>

This is inadvisable. There are a set of issues when running SMs of a<br>
different flavor in the same subnet.<br>

<br>
Yes, the SM election process will work properly. It relies on high<br>
priority and low GUID. So if OpenSM either has low priority or same<br>
priority and low GUID, it will become standby.<br>
<br>

<br>
That would be my recommendation: either run all OpenSMs or all<br>
Cisco/Topspin SMs in your subnet but not a mix of the two.<br>
<br>

<br>
Not sure what you mean by OpenSM acting properly. Both SMs have<br>
different policies for a number of things beyond the spec. There is an<br>
IBTA supplied white paper on management interoperability<br>
(</font></tt><a href=http://www.infinibandta.org/newsroom/whitepapers/mgtinterop_final_1.pdf><tt><font size=2>http://www.infinibandta.org/newsroom/whitepapers/mgtinterop_final_1.pdf)<br>
which I think is available to non members (by registering).<br>
