License for VEM 3 could not be
obtained. Please contact your
Cisco account team or partner to
purchase Licenses or downgrade

activate your purchased
licenses, click on
www.cisco.com/go/license .
The clock has been changed back
manually or through NTP, which
has invalidated evaluation licenses.
The problem is seen even if there
are enough permanent licenses
available to license the VEMs as
long as evaluation licenses are
present. You can look for the
following syslog message to find
the time when the clock changed:
2014 Jun 7 20:15:24 vsm-demo
VEM_MGR-5-VEM_MGR_CLOCK_CHANGE
: Clock setting has been
changed on the system. Please
be aware that, in Advanced
edition, clock changes will
force a recheckout of all
existing VEM licenses. During
this recheckout procedure,
licensed VEMs which are
offline will lose their
licenses.
1.
Undo the clock change using the clock set
command or uninstall all evaluation licenses
using the
clear license command.
2. Ensure there are enough permanent licenses
available before uninstalling evaluation
licenses.
3.
Verify that the modules are licensed using
the
show module vem license-info
command.
