<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am trying to partition my IB network but I don’t
seem to be able to understand the opensm man page.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>First it says “The default partition has P_Key value
0x7fff. OpenSM´s port will have full membership in default partition. All
other end ports will have partial membership.” but I don’t see the
difference defined between full and partial membership anywhere. Is it
possible the reference was to full and limited membership instead? Does this
partition have to exist on all CA’s so the SM can “talk”
them? Also it says the default partition will be created “unconditionally
even when partition configuration file does not exist or cannot be accessed.”
Will it also be created if the partition configuration file exists but does
not have a default partition defined?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Second, I see where CA’s can be members of multiple partitions
(have multiple P_keys). If a CA is in multiple partitions (has multiple P_Keys
assigned to it), which partition does it “send” on when the CA has
packets to send if more than one partition can reach the destination CA? Also
do switches (or any non CA’s) have to have P_Keys assigned for any
reason?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Just as a sanity check, my interpretation so far is that my
network should have a partition configuration file similar to the following. Can
anyone tell me if I have this correct? In this example configuration, I am trying
to create two partitions. One with rack one and two, the other with rack three
and four:<o:p></o:p></span></font></p>
