ftp transfer issue

[zxcv]

hi we are having transfer speed issue from two vm's .

Base O.S 11i v3

vmclient O.S 11iv2

we are facing tranfer issue from vmclient machines to remote location when doing ftp from vmclient to non-vm server .

Link sped checked from non-vm to non-vm its fine 5MB/s

But when cheked from VM to non-vm the transfer chokes.

Why is it so ???

Switch side port settings checked they are autonegotiation on .

P.S. This thread has been moved  from HP-UX > System Administration to HP-UX > networking - HP Forums Moderator

We'll need just a bit more information...

5 MBytes/sec is horrible for a 1000BaseT connection, but fairly normal for 100BaseT.

So what speed network cards are you using?

Auto-negotiation should be on *but* what is the duplex? If it is half-duplex, then run lanadmin -g #

where # is the lan card number (ie, 0=lan0, 2=lan2, etc). The second half of the statistics should be all zeros, specfically the collisions and errors. If there are errors, then auto-negotiation has failed. There is nothing you can do to fix the remote end from HP-UX. Talk to your network administrator and get the switch setup to match autonegotiation that is set on the HP-UX side.

>> But when cheked from VM to non-vm the transfer chokes.

I'm not sure what speed = chokes.

Are you saying that no data is transferred at all?

[Todd McDaniel_1]

Can you generate any traffic from vm to non-vm? it sounds like you may have a port issue... granted if by "choke" you mean zero data xfer happening.

otherwise, you may need to explicitly state the speed for the lan card in the conf file.

or i have seen where, if you have more than one lan, that the traffic may be asycnchronous, (ie the traffic is initiated from one lan but the return is coming over a different lan card.

check to be sure which lan is primary on each server and ensure the traffic is coming over that lan.

Hi Bill,

From that host belwo is the o/p;

root #/tmp >lanadmin -x 0
Speed = 1000 Full-Duplex.
Autonegotiation = On.

root #/tmp >lanadmin -x 1
Speed = 1000 Full-Duplex.
Autonegotiation = On.

root #/tmp >netstat -in

AS we can seeOerrors still showing errors.

The transfer gets initiated , but suddenly after few MB it halts and does not respond at all.

M trying to ftp 100MB of file , in the same lan from other server the file gets transferred in 20 sec,

whereas from this box sometime s it takes 40 sec , and sometimes goes in loop totally. ( only 20 MB gets transferred )

We are using 1000base t cards.

Hi Todd ,

How to check about 2 lan cards ??

and the trafic flow and reverse ??

We have two IVM guest O.S

Hi ,

HP response given below

"Thank you for your update, if it is taking less time in same subnet and taking more time for different subnet ,it shows there is no issue from server side, communicating with different networking devices are involved like routers, Please check with network team and confirm why it is taking more time for different network"

Found the below issues from the logs.

1. Stream resource pressure. 
   
   

527% of streams_sqmax has been reached

It seems that there is or there was a STREAM resource pressure

1. Suspecting this could be a cause for outbound errors. Found that stream patch installed is very low. Install the latest stream patch and its dependencies.

               PHNE_42014

1. Ftpd patch installed in the system is very low. Kindly install the latest ftpd patch and its dependencies.

PHNE_42661

1. Found HPVM Mandatory patches are not installed in the system. Which is having the fix for all the known issue.

Hi ,
Let me explain you the exact problem,

We have 2 rx2800 servers.
They both are in S/G cluster.
My application reqmnt is of 11iv2 and since tukvila processor doesnt support 11iv2 we had no choice but to go with IVM.
Hence we have two Base O.S of hpux 11iv3 and 2 IVM guests of 11iv2

The problem we are facing now is from 1st IVM when we are trying to do ftp transfer within LAN we are facing no issues no matter how many files ( tested 5 files each of 100MB goes in 8 sec to another hosts in same LAN )
But when i try the same number of files to transfer to DR site 1st,2nd file goes in desired speed, the 3rd,4th,5th file simply hangs.gets stalled.

From Second IVM we are neither able to transfer data within LAN nor WAN.

Now HP has recommended some patches ( PHNE_42014 and PHNE_42661 ) which require a reboot.

What am planning is do a cmhaltnode to remove second IVM from cluster.
Take ignite backup of 2nd IVM.
Install patches , take a reboot and then check ftp transfer .

Kindly let me know if am missing something.
