Hello Gurus,
I have E250 Machine( Solaris 8 ) with two Autochangers connected ( One L20
and one L40 ) having Gigabit Ethernet card ( X1141A) .
This Machine is used as Storage Node( term used in Legato Networker) . Lot
of people on this list must be using Legato Networker .
(I am using Networker 6.1 build 136 for those who are interested in the
version )
Problem :
When I start to take backup( 80 GB windows 2000 Machine with Lotus Notes
Option ) through networker using gigabit interface ,
backup failes after 12 GB /15GB or sometimes 30 GB giving rpc errors
timeouts.
Initially I thought that this could be the configuration problem of
networker . I posted my problem on networker mailing list , and lot people
responded that the error cause is because of network hardware . One person
having simmilar setup experienced same problem and he pointed out that this
could be because of Compaq NIC . However he did not have evidence since he
can test with another card .
I started to monitor netstat statistics on gigabit ethernet card , and I
found following . I just ftpd 100mb file from this machine to another
machine .
netstat -i -I ge0 3
and I am getting following
input ge0 output input (Total) output

Now you can see there are lot of input errors , I have escalated this
problem to SUN through vendor CTC Technology corporation.
I feel the Ierrs are not normal , and they are coming only on this machines
gigabit ethernet card , Hence CTC support replaced this card , reinstalled
driver applied patch but invain. Nothing changed .
Does anybody have such experiences with gigabit interface card on E250
Machine running Solaris 8 ?
I have applied 108813-09 patch on E250 Machine .
I am using GS504 Netgear HUBS ( fiber optic ) .
best regards,
- Rahul
