File copying slow in network

[trilok_pvp]

Hi All,

I have 3 HP UX servers.

I am facing a backup problem in HP openview backup. When i tried to copy the file from a Node1 to Node2, it takes 1 min to transfer the 12MB file. But the same file when i try to copy it takes 10 to 15 mins form Node 2 to Node1.

Run landiag against the NIC in Node2 (might as well check Node1 while you're at it) and look for collisions or other errors which might indicate a duplex mismatch.

hi,

check if you card have the same speed/duplex.

Hi,

I am in remote, How i can check the server in same duplex, any command to check the same.

[Michal Kapalka (mikap)]

hi,

use lanadmin and check the speed.

See above: landiag.

Then you'll have to check the switch and how you check that depends on the switch.

Hi i check all are configuration is same.

Earlier its works fine. last few days only it shows the problem

hi,

there could be some change on Network layout, ask the Net Admins for some changes.

But if between the same servers, one Node1 server to other server, it is fast. From Node2 to Node1 it is show.

Yes, but remember that going out to the network is one thing. But connecting TO another servers' network port is another thing. Check your lancard port speeds. Confirm that they are correct for the card and that they are the same on the switch's port. Then check with your Network Admin that the switch's/router's port is set the same.
If these are not harmonious you will get flakey connections (if any connection at all).

Also, although not knowing your network, it is possible that the traffic in one direction is taking a different route then the traffic in the other direction. This too can affect your speed since you may be traversing different routers and/or making more hops.
Try doing a trace route from both sides and see what way the traffic is going.
