Re: rhel5 nic problem
Hi,
May be you can try these commands in Linux.
ifconfig $interface -- show the information for $interface (usually something like ifconfig eth0)
ethtool $interface
Thanks
I work for HPE.

is the card still there ? if it does not show then it is probably toast and in need of replacing.

Re: rhel5 nic problem
There are many ways to check if the NIC card is working or not.
1. On the hardware level, first check if the NIC port has the link light and activity light turning on. If yes, on to step 2.
2. Check the NIC is recognized in RHEL.
# dmesg
3. Check if the NIC interface shows an IP address. To do this:
# ifconfig ethX
If no IP address, consider the NIC configuration for either DHCP or static.
4. Next check if you can ping some other known ip address (in the same network):
# ping -I ethX 192.168.1.1
If you find any issues, check the driver being used for the NIC:
# ethtool -i ethX
If the driver information is displayed, check if the driver is loaded:
# lsmod
Note: you can pipe the output to grep for the driver name returned by ethtool. E.g.
# lsmod | grep
This should give you a fair idea of how the NIC is working, and where the possible issue could be. Good luck!
