I have the problem, that a .iso that I mount in Virtual Media disconnects. The time after it does that is random. It happens only from Windows 7, from XP it works. I tried IE 8 and Firefox 3, as well as Java 1.4.2_19 and 1.6.0_18. iLO version is 1.94 on a DL380 G4.
This is really a problem for firmware updates, I don't know what happens if the disconnect happens in the middle of a update...
Any ideas where the problem could be?
Solved! Go to Solution.

SolutionThis could be the TCP checksum equal to 0xFFFF issue we've seen sometimes when doing Virtual Media with Win7.
iLO rejects these TCP packets because the checksum is wrong, causing virtual media to disconnect.
We patched iLO2 TCP layer in version 2.01 to follow RFC 1624 recommendations but, iLO-1 is still the old TCP code because it is an End of Life product.

Re: Virtual Media disconnects
I upload the last 429 packets, since the whole capture is way too big for the forum and bad compressable.
Something to add: The unmount only happens, when the media is actually accessed, for this test I just copied the contents to a local folder.

Re: Virtual Media disconnects
It all begins with packet number 425. iLO TCP layer ignores this TCP segment because of the wrong checksum. Checksum here should be 0x0000.
VMedia client retries sending the same segment with checksum 0xFFFF few more times and iLO keeps dropping them. After few seconds retrying, the Vmedia client finally times out and closes the socket.

Re: Virtual Media disconnects
iLO-1 is an End of Life product. No more firmware releases are planned for it.
