Removing Installed Patches
Use this procedure to uninstall one or more patches and to roll back the ACS SE to the version that
existed before the patch installation.
To roll back a ACS SE system patch:
Step 1
Connect a console to the ACS SE console port. For the location of the console port, see
Figure 1-2 on
page 1-5
.
Step 2
Type
rollback
and the name of the patch application that you want rolled back. Then press
Enter
.
Tip
If you do not include the specific patch application name as a parameter following the
rollback
command, the system displays the list of patches that can be rolled back. Use this list to identify
the patch application name, type
rollback
followed by the patch application name, and then
press
Enter
.
Result
: The system displays the confirmation message:
Are you sure you want to rollback [patch name]?)(Y/N):
Step 3
Type
Y
to continue.
Result
: The system displays a series of messages that include:
Rolling patch back
Rollback process initiated successfully
Successfully rolled back ‘[
patch name
]’ to 0.

Understanding the CSAgent Patch
In ACS SE the
CSAgent
service is implemented as a pre-installed patch. You must stop
CSAgent
before
you can install any patch or upgrade. Although, as a patch, the
CSAgent
can be rolled back, the preferred
method for disabling this service is simply to stop it. Once stopped, the
CSAgent
service does not restart
when the system is restarted; you must explicitly restart the service for it to operate. For more
information, see the
User Guide for Cisco Secure Access Control Server
.
