trouble shooting NFS on open solaris. Keeps dropping connection.

I am able to connect to a NFS share no problem. It seems like every 4 or 5 min it drops the connection. I was able to keep a constant ping going and never lost a packet durning the drops. Anyone have any ideas or basic things i can check?

Thanks in advance.

In such cases I always go to my ethernet switch. Hopefully yours has some intelligence and a web-enabled front end.  The switch will generally tell you what is going on.

Solaris is often unable to correctly auto-negotiate duplex settings with a link partner (e.g. switch), especially when the switch is set to 100Mbit full-duplex. You can force the NIC into 100Mbit full-duplex by disabling auto-negotiation and 100Mbit half-duplex capability.

Example with hme0:

Make the changes to the running system.
# ndd -set /dev/hme adv_100hdx_cap 0
# ndd -set /dev/hme adv_100fdx_cap 1
# ndd -set /dev/hme adv_autoneg_cap 0

Thank you Ganjos. I am getting the vendor who supports the box and i am going to see if they can hard code it for me 1000full. I am just getting really bad performance to that box. So maybe hard coding it on both sides to 1000full will help.

I'll let you know.
