Thanks Ryan.<div><br></div><div>There is certainly confusion surrounding this concept of partition alignment for me. Considering Erick's original statement of, <span style="line-height:1.5">"</span><span style="line-height:19.7999992370605px">For those of you sill out there doing upgrades from pre-9.x to 10.x and running nto the unaligned partition issue...", I am trying to wrap my head around when I might see this.</span><div><div><br></div><div>One Cisco employee says:<br>"For customers using jump upgrade (comming from 6.x, 7.x) a rebuild once getting to CUCM 9.X is mandatory since the VM will miss-align during the process."<div>Source: <a href="https://supportforums.cisco.com/discussion/11903591/error-unsupported-partitions-unaligned-after-upgrade-ucm-912">https://supportforums.cisco.com/discussion/11903591/error-unsupported-partitions-unaligned-after-upgrade-ucm-912</a></div></div><div><br></div><div>But of course, the upgrade scenario Erick describes is not a Jump upgrade, as he describes going from 8.6 to 10.5. But, to continue on the Jump upgrade process for just a moment longer...</div><div><br></div><div>Cisco Live Breakout BRKUCC-2011 on slide 28 shows that a DRS export/Rebuild/Import is required for Jump upgrades to 9.1(2).</div><div><a href="http://d2zmdbbm9feqrf.cloudfront.net/2014/usa/pdf/BRKUCC-2011.pdf">http://d2zmdbbm9feqrf.cloudfront.net/2014/usa/pdf/BRKUCC-2011.pdf</a><br></div><div><br></div><div>In the accompanying video for this Breakout, at the 8:04 mark, the presenter starts to talk to this process, and describes disk alignment pretty well. Then, at 8:34 touches on how disks can become unaligned, but I feel like he didn't articulate the point very well. Would it have been accurate to say that the install of 6x on VMWare, and the fact that there is not a supported OVA for it, is what caused the disk alignment issue in this process?</div><div><br></div><div>So now, it appears to me that this concept is only applicable to VMWare and not MCS bare metal deployments. Meaning, you could only possibly have unaligned partitions if on VMWare. Is that true?</div><div><br></div><div>If so, then it would also seem to me, there's only two possible ways to have this issue of unaligned partitions:</div><div><br></div><div>1. If you are on VMWare now, with aligned partitions, and then you muck with the VMWare settings for the guest, specifically the ones pertaining to the disks. (do we know which settings?)</div><div>2. If you deploy new on VMWare without using an official OVA, but rather you just manually build out the specs of the server, and miss the 64K boundary for the disk alignment.</div><div><br></div><div>If we read Erick's other statement: "<span style="line-height:19.7999992370605px">I used 10.5.2 upgrade media to upgrade from 8.6, at that point you need to do the fresh install and DRS restore routine to correct the unaligned partition issue.", then it would seem as though his server was running with unaligned partitions on 8.6 to begin with and this is not the rule, but rather the exception.</span></div><div><span style="line-height:19.7999992370605px"><br></span></div><div><span style="line-height:19.7999992370605px">The assumption that he had unaligned partitions existing in 8.6, would then further imply he was running 8.6 in VMWare and not bare metal. He didn't state that, but that's my guess.</span></div><div><span style="line-height:19.7999992370605px"><br></span></div><div><span style="line-height:19.7999992370605px">However, since there are official OVAs for 8.6 and 10.5, I'm guessing the only reason there was unaligned partitions in 8.6 is because one of two possibilities:</span></div><div><span style="line-height:19.7999992370605px"><br></span></div><div><span style="line-height:19.7999992370605px">1. The original 8.6 install on VMWare was done without the official OVA</span></div><div><span style="line-height:19.7999992370605px">2. The official OVA was used, but someone changed the disk settings some time afterwards.</span></div></div></div><div><span style="line-height:19.7999992370605px"><br></span></div><div><span style="line-height:19.7999992370605px">How'd I do Ryan?

Nothing about an upgrade from 8.6 to 9.x or later guarantees unaligned partitions. You will only get the error because your partitions were unaligned already.

I don't understand the scenario you are describing. At first you talked about upgrades from pre 9x to 10x. Then you mentioned fresh installs of 10.5(2). Then you mentioned restoring publishers. So, do we have: upgrading, installing, and restoring all affected
by this bug?<br>

<div>There is a bug that was opened on 12/30 regarding the fresh install with 110.5.2.10000-5</div>
<div> and installing the subscriber(s) ater the restore to the Publisher.</div>

<div>You get about 99% complete and run into a critical error. The install log shows errors related to your web administrator account.</div>
