vWLC serial number can change if using disaster recovery.
I know this was published before but I cannot find it at the moment so I will republish.
If a person is running DRS for VMWare or any type of disater recovery solution that moves the vWLC to another host, the serial number of the vWLC will change. Since our SN is node-locked to the UUID in VMWare, if the UUID changes, the UDI (and serial number) of the controller will also change. The only way to avoid this from happening is to maintain the UUID in VMware .
Here are a couple of VMWare KB articles:
Changing or keeping a UUID for a moved virtual machine (1541)
On the line w/ Cisco Licensing right now. VMotioned my vWLC running 18.104.22.168 to another node in the ESXI cluster. After I had rebooted, poof... all licensing was missing. Luckily we should have the license keys rehosted here shortly so I can get my APs back online.
I don't see version 22.214.171.124 listed as a version with the known fixes, just the 8.0(100.0), and 8.0(72.160). Can anyone confirm the bug is fixed in 8.0(115.0) as well please? I would prefer not to vMotion again and repeat this entire licensing exercise if unnecessary. ;) Thanks for the posting!
