I have enabled PXE boot on NIC2(1Gbps) on a cluster node and enabled boot from that NIC2. A separate DHCP server and tftp server(both on same node) is running correctly.

When the node boots from NIC2 it broadcasts DHCP request to obtain its IP but after sometime it exits PXE mode(perhaps) notifying that no DHCP reply found....! and then it starts booting using 2nd option i.e. harddisk and then Red Hat ES 4 starts loading. During loading eth0(NIC2) gets correct IP address from DHCP server and then computer boots correctly.

How can i correct this problem i.e how can i make computer to get its IP successfully ftom DHCP serever at the initial time.

Waiting for reply
Thankyou

PXE boot can be pretty particular, regardless of what operating system you're using. I'd first make darned sure all firmware and BIOS is updated before worrying about the OS.

Also, no doubt it generated a PXE error code. Which is it? You may need to add additional parameters to your DHCP configuration to get it to work consistently, so check those out also.

Dear sie John Jonson

The error code you mentioned is PXE-M0F and then exits PXE boot agent...
the dhcp server is running correctly as nodes picks up their ip during OS load...

Waiting for response
