HDHR-3CC - Firmware Update - No Cable Card Detect. [#124016]
I don't want to sound like a broken record here, but I'm sure we've been in a situation where the app team comes in late at night and upgrades their application, they give each other high fives and head home only to come in the next day and their application isn't working right. Of course it can't be the change they just did, they had a wonderful test plan that surely covered all the possible scenarios. It must be an infrastructure problem. Let's get the compute guys and network guys involved surely they must have monied with something after we tested....
Literally this tuner was fine and tuned to a channel when the firmware upgrade took place. Nothing else changed. The cat didn't even fart next to it. It rebooted for the upgrade and never came back to a usable state. Typically in my experience where there's smoke there's fire. A large portion of IT outages are due to change and it is usually very difficult to determine what changed in order to fix the problem. I feel like I have gift wrapped and put a bow on the delta, but it can't be that? Now, I don't profess to be a cable card wizard but I consider myself to be a pretty good sleuth when it comes to finding an issue and correcting it.
We have ruled out the cable card.
We have ruled out power.
We can see in the logs the cable card is detected, that would seem like physical connectivity is ruled out.
What else if left? How can we rule it out?
