When the phone is booting up, it lists, from a file on its flash, that it has no TVS servers, until it has read the configuration file and established the CM nodes from that device pool. TVS is running on all hosts in the cluster, including the TFTP, which it seems to want to fall back to, to verify its configuration and ITL initially. For whatever reason it insists on using the TFTP, yet, it wants to connect via IPv6 which just can’t work and doesn’t. It’s placed me into a situation where I want to turn off V6 but, have to do so in the phone’s config, and can’t change the phone’s config until I turn off V6 (or erase the ITL). <o:p></o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> I will inspect the ITL on the phone again to see what’s going on – the nodes should all be listed but the ITLs hash has changed. I’d love to understand just what is going on with this. As we were talking earlier about here, the license documentation for the 8 upgrades should have come with a singing telegram or at least a stack of bright red paper drawing our attention to this feature. There’s a lot that’s new in the UCM and it seems easy to get underwater on the everything that comes up, but this just seems too easy to run afoul of bugs or problems which can hose over your cluster. If we have to erase, we have to erase, but, I don’t want to get into the habit of planning to or having to erase security certificates if there’s a way to correct the issue.<o:p></o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p>

style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> From what I can read, TVS has been a thrill ride for those of us lucky enough to run afoul of SBD. I’m hoping we haven’t run into such a situation here but I have a question. We just pushed 9.3.1 out to devices from 9.1.1SR1, with peer firmware sharing enabled. This went miserably and left a lot of devices stranded at 9.1.1 or at an “Upgrading” screen. Working with TAC on that but so far nothing. We began receiving reports from end users that their directories were missing, they can’t change ringers, etc. Last time this happened we had phones that had picked up a bum ITL from a partial rollout, and we had to erase them by hand.<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> <o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> This time that shouldn’t have been the case – it was just a firmware upgrade. However, it looks like some of the phones that have gone to 9.3.1 have decided that they want to use IPv6 when talking to the TFTP to verify their initial configurations, when they have no TVS server list built on the device. In looking at the phone console logs, you can see that the device is in “IP mode 1” and tries to connect to TFTP, say “192.168.0.1 :: “ which is obviously not a V6 address. We’re not running V6 so it has no address bound. No traffic leaves the phone, but, the phone says it timed out (EAGAIN) connecting to the TFTP and won’t verify the ITL/CFG/etc.<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> <o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> What I’m looking at it is setting V6 to off at the cluster, but, I don’t see any way to repair this on affected devices (could be a large amount) other than erasing the ITL, or deploying IPv6. Given the leg work that could go into identifying and taking care of these devices, it’s arguable as to which one would be harder at this point.<o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> <o:p></o:p></span></font></p></div><div><p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> Any comment on this with this firmware?
