<p class=MsoNormal>Adam,<br>
<br>
I do not have expert knowledge on this topic, so i would like to describe my
situation again with picture illustrations.<br>
<br>
we have a cm6011 named CM server acts as first node (as publisher) the ip
address is 10.0.255.251<br>
and a cm6012 named server acts as second node (as subscriber).the ip address is
10.0.255.252. (I have installed the CUCM 6.0 on this server myself. i
configured it as second node and no DHCP service activated.) <br>
by the way our default gateway's ip is 10.0.255.254<br>
all the services are running on the first node (tftp,dhcp and others)<br>
<br>
the picture link of servers: <a
href="http://img26.imageshack.us/img26/521/serverlist.jpg">http://img26.imageshack.us/img26/521/serverlist.jpg</a><br>
<br>
<br>
<br>
In current structure, the second node is just an image of the first. As i
described before, when i make cm6011 offline, i can establish connection CM via
second node's ip (10.0.255.252). But the ipphones don't come online. <br>
<br>
According to your instructions; <br>
1)i configured a new CM group named "cm2" which only consists of the
second CM server. (The default CM group consists of both cm6011 and 6012) the
picture link: <a href="http://img26.imageshack.us/img26/9725/cm2x.jpg">http://img26.imageshack.us/img26/9725/cm2x.jpg</a><br>
2)i configured a new Device pool with selecting Cisco Unified Communications
Manager Group as the newly created CM group "cm2" (the picture link: <a
href="http://img91.imageshack.us/img91/4007/dvcepool.jpg">http://img91.imageshack.us/img91/4007/dvcepool.jpg</a><br>
<br>
when i get to the phone's web page via it's ip address here is the info below:<o:p></o:p></p>

<p class=MsoNormal style='margin-bottom:12.0pt'><br>
as you see, although CM1 is set to secondary node (cm6012) for my phone, it
still gets first node as active. <br>
if you look at the device pool picture, it indicates that there is currently
one member, i think this is because i configured my phone's Device pool as cm2.<br>
<br>
Thanks for your help.<br>
<br>
Kind Regards.<o:p></o:p></p>

<p><span style='font-size:11.0pt;color:#1F497D'>To get the desired behavior CM
group should be an ordered list of the CM’s to which your devices, not just the
secondary node. After modifying the CM group reset the phone so it can
get its new config file to take the change. Verify the correct Active and
Standby CUCM’s are listed on the phone’s web page and you should be good to go.
