Device registered with wrong IP (how to change it?)

I had static DNS entry for a device (IP xx.xx.xx.yy)
This device was off for some time, got different IP from DHCP (xx.xx.xx.zz), dynamic DNS added this new IP to the DNS entry

I now have device in ZCM with old IP & I can not unregister it from zac unr (gives error: Unable to unregister the device with the server)

The agent on the device does not update the IP in ZCM

Had to zcm unr -f (which unregistered locally) and then zcm reg worked fine (picking up the same object)

Isn't agent supposed to update the ZCM object?

I've been seeing this a lot lately. Haven't been able to figure out the reason/culprit, but so far 3 times it's been different laptops. It usually takes several reboots and waiting about 10 minutes before ZCM finally updates.

In one case, we had to reinstall the agent for no apparent reason (ie, it obviously worked many times, just fine, before and then suddenly stopped working).

I've not opened an SR yet on this.

Only thing I can suggest is:

a) put the agent in debug logging and get the zac zeninfo stuff.

I've done that, but couldn't really make heads or tails out of the logs.

Re: Device registered with wrong IP (how to change it?)

Yes and it does, but most likely something about the registration broke
unrelated to the IP change. This is why the device would not reconnect.

It also could be related to some "corrupt cache" issues which impact
registration and type stuff.

Corrupt Cache issues should mostly be corrected in 11.2.3, though not
all causes of something like this are related to corrupt cache.
