RE: oracle 10.2.0.4.3 RAC RHEL 5.4 x86_64 nic bonding + trunking (etherchannel)

I have logged a case for that in the past 
(http://freekdhooge.wordpress.com/2009/11/03/two-oracle-rac-bugs-on-the-wall-two-oracle-bugs-take-one-down)
It should have been fixed in the april psu patch (switching to ethtool instead 
of miitool), but I did not had the change to verify it

Not sure about 10.2.0.4, but 11.1.0.6/11.2 still uses mii-tool in racgvip (VIP
failover). Notes from racgvip/11.1.0.6 script:

" - if mii-tool reports the link is down, use ifconfig to verify the link
   status.
 - use mii-tool to check if the interface is up. If mii-tool does not exist
   or fails, "ping -r -I <interface> <default gw>" will be used instead."

but mii-tool executed on bond interfaces seems to always to return "10 Mbit,
half duplex, link ok", not to mention that mii-tool is marked deprecated in
it's own manpage (checked OEL 5.5 a few seconds ago).

BTW: There is "Bug 8333262: VIP NOT FAILING OVER WHEN CABLE UNPLUGGED" with
workaround "do not pull cable" :))))))))

You can fallback to old code by setting MIITOOL variable
to /some/not/existent/file.
