Couldnt fix Virtual IP permanently on RHEL 5.3?

Hi Gurus

I have installed RHEL 5.3 64bit version on HP Compaq 8100 Elite CMT PC and was trying to configure two IP for my ethernet card. As most of the people know, "ifconfig eth0:1 ......." working fine when assign the second IP to the system. But to make it permanent i have added a file "ifcfg-eth0:1" with appropriate details under /etc/sysconfig/network-scripts directory. Though the parameters are correct, the system does not take the Virtual IP when i boot the system or restart the network service.

After searching google, i came to know that "ifdown eth0:1; ifdown eth0; ifup eth0" commands should work fine in RHEL 5.3 to bring both the IPs up, but which is also not working fine. Please help me to solve this problem.

Am getting the following error while restarting the network service after created a file "ifcfg-eth0:1" under /etc/sysconfig/network-scripts.

Hi Gurus,
Some more update. I have used the following format to assign Virtual IP now and could successfully get assigned both the IP after network service restart.

Quote:

# Intel Corporation 82546EB Gigabit Ethernet Controller (Copper)
# Alias for eth0
DEVICE=eth0:1
IPADDR=X.X.X.X
ONBOOT=yes

When i rebooted, the machine has come up with its primary ip only. Again, network service restart makes both the IPs up.

It didnt help even after file "ifcfg-eth0:1" has been added under /etc/sysconfig/networking/devices and /etc/sysconfig/networking/profiles/default directories.
