MAC filtering and booting PXE

[Cristian Casablanca]

Hi!

Here's my problem with PXE in Ignite UX

A client has two Superdomes, and each one have a Ignite server (backing up the other SD's vPars). I have reserved MACs in /etc/opt/ignite/instl_boottab for assigning the right IP to every machine (no DHCP).

The questions are:
1. When trying to boot a vPar by PXE for recovery is the first replying server the one that will boot the machine, isnt it??
2. What happens if it's not the right Ignite server for that Superdome?
Does it checks it's not a registered client for that server, and don't reply to the boot petition?
3. Is there any util for checking Ignite PXE like bootpquery?

PD: If there's anything that you couldn't undestand, please ask for explanation... I almost forgot my english :D

Thanks in advance,
Cristian Casablanca

Shalom,

My understanding is that Ignite does not use PXE at all. It interferes with and can be confused by having PXE servers on the same subnet

IF your Ignite server is on the same subnet

boot
intervene
bo lan.ip_of_ignite_server install

# example
bo 192.168.0.10 install

Use the IP address of the boot helper if thats what has been set up.

This methodology should avoid any issues with accidently choosing to boot from some PXE server that can not possibly service Ignite in the first place.

I was thinking about booting with

boot lan install

and I was wondering about what server should reply, but with your note, replacing the "lan" with its IP, I think it solves the trouble...

Thanks a lot!!!
