Maintenance Mode

All,

Is there anyway to disable maintenance mode?  I have a very large customer that is having a lot of problems with their TC6.1.2 codecs going into maintenance mode for the silliest things.  Over the weekend, one of their codecs lost power briefly; when it came back up it booted into Maintenance Mode and this morning staff went to use the codec and could not.

All they had to do was restart the codec and it came up fine, so why would it have gone into maintenance mode to begin with?

From our experience we are not finding maintenance mode very useful, would rather have the cyclic reboots back and we have run into several codecs that you cannot get out of maintenance mode.      

Thank you,

Maintenance Mode

I do not fully agree, I think the maintenance mode is a great thing.

In general the codec should not get into this mode unless there is some critical

issue.

The question is sure, if you experience this quite often, whats the cause.

The software or the hardware of this/these endpoint(s).

Think you should investigate why it is crashing in the first place.

Besides that. You could ask for a feature request to have a configurable

(like 5 min and up) counter which triggers an automatic reboot when getting into

maintenance mode.

But that should be optional, as I like the behavior how it is now :-)

Martin,

In previous software releases, if you unplug a codec and then plug it back in, it would most likely boot right back up and be usable.  In TC6.2.1, the customer is sometimes losing power on their codecs and when the power comes back on, the codec boots into maintenance mode.  The customer does nothing else except restart out of maintenance mode and it boots up fine.  This tells me that there was nothing wrong to begin with, so why did it go into maintenance mode?

Secondly, we have almost close to a dozen fully documented RMAs where the codec never comes out of maintenance mode, never had this issue before it came along.

Maintenance Mode

Perhaps the 2nd software image on the codec that's coming up in maintenance mode is corrupt (or an older one), so on an unexpected reboot, it comes up on this non-functioning software and gets stuck in maintenance mode.  Rebooting it again is likely then switching to the "working" software.  You can try doing the software upgrade on the codec twice (to get the newer version in to both the images in flash) and making sure they're both the same.

Maintenance Mode

Wayne,

Is that common for one of the images to hold the previous version of firmware?

Yes, the codec will hold two images.  You can switch between the two using the "selectsw" command in the CLI (when logged in as "root") to switch between the two

$ selectsw

image1 [ACTIVE] [SELECTED]

image2

You can also use the GUI in the newer versions of TC6 - look under Maintenance, System Recovery, Software Recovery Swap - this also shows what version the two are:

You are currently running TC6.2.1 69d401c.

Switch to software: TC5.1.8 303428...

When you upgrade, it replaces the non-current image (image 2 in the selectsw example above) with the new version, leaving the other version (image1) in place, then once the upgrade process has completed and you've rebooted, the 2nd image becomes active.

The older version (image1) is still present in the original, now non-active slot.  If you then perform the upgrade again, it'll overwrite the image1 version and you'll have the same version in both image1 and image2.

I'd recomend that this is done and that you only have different versions in the two images if you're doing soem testing and need to be able to roll back quickly.  Having the same version in both slots ensures that if one becomes corrupt for any reason, the unit will still be able to boot with the other one and still have the same capabilities/version.

Maintenance Mode

At any rate, I guess we can try reloading the firmware again on any codecs that may seem to be affected and see if it resurfaces with any of those codecs.

Maintenance Mode

Wayne,

I had thought about it, but I don't believe the TC software can pick which image it wants to boot from automatically.  I believe you always have to identify which image to boot from manually; hence the reason there is a software select option within the maintenance mode.

Thank you,

Yes the codec will have two versions when it was upgraded, one containing the current and the inactive the old one.

But if it crashes it will not flip, from how I see it it only changes if you manually tell the system to do so.

I would challange tac to get me more info why it fails so often.

If you see that an older version works much better it might be worth considering downgrading.
