NetworkManager component
To ensure that RFC3442-standard classless static routes provided by a DHCP server are processed correctly when using NetworkManager, the following lines should be placed into the /etc/dhclient.conf file or, if using per-interface DHCP options, the /etc/dhclient-<ifname>.conf file: 
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
option ms-classless-static-routes code 249 = array of unsigned integer 8;
also request rfc3442-classless-static-routes;
also request ms-classless-static-routes;

The above lines will ensure that RFC3442 classless static routes are requested from the DHCP server, and that they are properly processed by NetworkManager.
iprutils component
Users of the IBM PCI-E Gen2 6GB SAS RADI adapter (FC 5913) in Red Hat Enterprise Linux 6.2 may encounter the following issues:
  • Updating firmware on a storage drawer that is connected to the adapter mentioned above using the iprconfig command fails.
  • Attempting to change the asymmetric access for an array results in a failure. Additionally, not specifying asymmetric access as an option to the iprconfig command results in a failure as well.
