Adding hardware to a Red Hat Linux Box
I also need to know what commands I need to issue if I am adding storage to Linux box from EMC Symmetrix, like in HPUX we do ioscan to see the newly added hardware.

Re: Adding hardware to a Red Hat Linux Box
If you have qlogic cards, you san for new LUN's this way.
echo "1" > /sys/class/fc_host/host0/issue_lip
echo "1" > /sys/class/fc_host/host1/issue_lip
Do this for each "hostx".

Re: Adding hardware to a Red Hat Linux Box
Tony Cicone has given you a good answer.
from those commands you can get live information about luns presented to each port of the HBAs.
Remember you have to run this command manually every time you add a new lun to a linux host.
About the network card
kudzu - is the command you have to run
check the man page for "kudzu"
as a trial you can run "kudzu -p" this will run a probe but will not try to configure the newly attached device.
i have come across that this didnt work some times due to missing kernel modules. in that case you have to download the driver for from the vendor and install that. this will add all required modules to the kernel. remind you this might need a reboot.
the other thing you can try is
"cat /proc/net/dev" command this will show you about all active interfaces.
Good Luck...!

Re: Adding hardware to a Red Hat Linux Box
You can check lancard by
#dmesg | more
#ifconfig | more
In linux no ioscan command is available.
so , You can check it by
#fdisk -l

Re: Adding hardware to a Red Hat Linux Box
once you add lan (hardware) card in linux box perform below.
~]# service kudzu stop
~]# service kudzu start
Checking for new hardware [ OK ]
once you add storage, you can do fdisk -l or if you want to check in gui then type
hwbrowser
let me know how it goes, thanks
