Cumulative update package2 for SQL2005 SP2 - cluster aware?

Hi,
Is the "Cumulative update package2 for SQL2005 SP2"
(http://support.microsoft.com/kb/936305) cluster aware? Or do it need to be
installed on each cluster node?
Thanks!

Hi
You need to install service pack on SQL Instance (NODE1) and binaries get
copied to the second(passive) node.
If you have ACTIVE/ACTIVE configuration then you need to install an both
sql instances
