Improperly formatted value for 'tftp-server' error while booting the target from LAN

Hi,
I wish to install solaris 10 on a target machine (t1000) by using Jumpstart. I have configured by jumpstart environment for the same. When i boot the target with the option "boot net -v install" i get the following error...
{0} ok boot net -v install
Boot device: /pci@7c0/pci@0/network@4 File and args: -v install
Improperly formatted value for 'tftp-server'

Any idea what can be wrong ??

If that's all the output you're getting, it doesn't look like it's getting out anywhere. So I don't think it's your jumpstart environment. From the OK prompt, what's the value for network-boot-arguments?

OK printenv network-boot-arguments

Do a man on eeprom, and you can see details for this field. Blank it out if anything's there, by default there should be nothing.

Thanks Diabolist for replying. I got the problem. The IP address and tftp-server configuration can be obtained by the client by using either RARP or DHCP. We need to specify this in the boot net command. I did the following and it worked fine.

boot net:rarp -v install

If DHCP was used, we would have to do the following...

boot net:dhcp -v install

ok>boot net -install
