<p>The primary reason for a cluster reboot after a device package install is to refresh the RIS Data Collector, TFTP, Tomacat, A Cisco DB (and one other ... I think) services; which is needed when the device package includes the installation of device model
support not previously supported. If the device package does not include additional model support not previously supported; it's usually not much more than a collection of firmware that would just require a TFTP refresh in the cluster (although, either way,
it does update the default load values under <i>Device->Device Settings->Device Defaults</i>).</p>
<p><br>
</p>
<blockquote>
<p><i>If you are not prepared to push the new loads to all devices; I suggest a BAT export of the Device Defaults BEFORE installing the device pack and then a BAT import of the same Device Defaults export AFTER the device pack is installed, BUT, before any
cluster reboots or TFTP service refreshes (you can always record or BAT export the references of all the new loads after you install the device pack but before you restore them to the previous values).</i><br>
</p>
</blockquote>
<p><br>
</p>
<p>The device package, <i><span id="955190617A1D948116E4D9801B3804EFA29BEFA1" class="overlay_img">cmterm-devicepack10.5.2.14082-1.cop.sgn</span></i> adds device support for the Cisco Wireless IP Phone 8821 (<a href="http://www.cisco.com/web/software/282074299/134616/cmterm-devicepack10.5.2_14082-1_Release_Notes.pdf" class="OWAAutoLink">http://www.cisco.com/web/software/282074299/134616/cmterm-devicepack10.5.2_14082-1_Release_Notes.pdf</a>).
When you install the device package, any changes to Informix for the new model support are made during the device package is installation; the cluster restart is to ensure all required service refreshes are complete cluster-wide.</p>
<p><br>
</p>
<p>In <i>theory</i> (I say theory because I simply have never attempted this), you could complete the device pack install (on all cluster nodes) and then install
<span>10.5(2)SU3a on the cluster nodes and do a single reboot. However, in full disclosure, I have never tried it that way .... the logic is sound though and I have every reason to think it would work fine.</span></p>
<p><span><br>
</span></p>
<p><span>Personally, I am averse to doing <u></u><b><u><i>anything</i></u></b> that I think is even remotely risky in a production environment without testing. If this were my deal (and I had the extra time); I'd spin something up in a lab and just 'try it'
first to see if anything blows up. Using dCloud may be an option too if you have a
<i>really</i> good connection (uploading the uc update and device package files could prove cumbersome otherwise).</span></p>
<p><span><br>
</span></p>
<p><span>Beyond that, never fail alone ... get a TAC case open; if TAC says it will work ... GREAT, if something does go wonky you have recourse. If TAC says no ... there is your answer AND, it gives you business justification for needing two (2) separate cluster
reboots.</span><br>

<b>Subject:</b> [cisco-voip] CUCM Cluster SU install + device Package</font>
<div> </div>
</div>
<div>We are going to be performing an update to the latest SU on a CUCM 10.5 cluster soon. The latest Patch was released on Jun 2016 while the latest device package is from August. My main question is, Can I run the Device Package Installer, not reboot the
cluster, perform update and do the switch version? Will I have do do them separately? I’m trying to avoid having to do two cluster reboots since this is a 24/7 Operation and we scheduled a six hour window for the upgrade on a 5 CUCM/ 2 CUC Cluster
