Примечания к выпуску для Cisco Cisco Flex 7510 Wireless Controller

You can check the Emergency Image Version by entering the show sysinfo command on the WLC CLI.

Following are the reasons why you must install Cisco Wireless Controller Field Upgrade Software, 
Release 1.10.0.0:

The Emergency Image Version 8.1.102.0 has kdump facility enabled to handle kernel panic dump 
collection. If you do not upgrade to Emergency Image Version 8.1.102.0, any kdump function may 
cause the Cisco WLC platform to not work as expected on a kernel panic or watchdog failure. The 
following messages are displayed:

INIT: Sending processes the KILL signal

INIT: Entering runlevel: 3

INIT: cannot execute "/bin/gettyOrMwar"

INIT: cannot execute "/bin/gettyOrMwar"

INIT: cannot execute "/bin/gettyOrMwar"

If the Emergency Image Version is prior to 8.0, the following error message is displayed during 
bootup:

?failure to setup the dump capture kernel?

The Cisco WLC disables the kdump functionality and continues.

Upgrading to Cisco Wireless Controller Field Upgrade Software, Release 1.10.0.0 removes this 
error message.

 lists the components that are upgraded after you install FUS for various controller platforms.

Ensure that there are no power outages during the upgrade. Power outages during the upgrade may lead 
to the controller not being usable.

This release of the Field Upgrade Software is applicable to Cisco WLCs that are installed with the 
controller software release 6.0 and later.

You must install the FUS image only once.
