8) And here is where the issue must be.
I found that ethtool and mii-tool don't agree in the link status. First one indicates it as dow, while mii indicates up.
And here is the output for ethtool and mii-tool:
Code:

I think I should believe ethtool, but I see the LED lights green, the cables is properlly plugged (tried with two different ones).
Any idea why interefaces are down and can't communicate?
It really doesn't believe the cable's plugged in. The LED's might just be hardwired. mii-tool talks with the transceiver itself, so it's the one I'd trust... Very strange that it autonegotiated a 100baseT link with a 1000baseT peer.
Have you tried a normal cable, not a crossover cable? I've sometimes experienced odd behavior with ports capable of autodetecting the cable type. You might also try forcing the speed and duplex, gigabit links often have problems negotiating -- though if you've discovered a gigabit interface that's incapable of negotiating with itself that's certainly something new!
I see you have other network adapters in your systems. Are they in use?
I wondered too. I assumed it's a two-port nic and wondered why eth2 and not eth0 or eth1. Besides I looked at the support pages @ hp.com, namely the driver download section and I found the driver the OP has mentioned (e1000), but there is a e1000e too. I don't know what's the difference between them. There are even at least two non-intel drivers (Broadcom, QLogic)

Hi
In the vio server when I do # lsattr -El hdisk*, I get a PVID. The same PVID is also seen when I put the lspv command on the vio client partition. This way Im able to confirm the lun using the PVID.
Similarly how does the vio client partition gets the virtual ethernet scsi client adapter... (1 Reply)

Hi grus,
has anybody tried for Sun cluster interconnect normal cable ,, I mean not interconnect .. What do u think ..does it support this ?
Not long ago I tried Veritas cluster and its interconnections work great with normal cable .. I wonder what will Sun cluster say to it :)) (3 Replies)
Hi all,
Is there any difference between a null modem cable or a modem cable ?
i assume that a null modem cable is a normal cable that i used from cpu serial ports to a modem for dialup.
please correct if i am wrong,
