Hi
We are installing the HBA on our servers ( N4000 and L1000 ) . We don't have a free slot on these servers which can support the HBA . ( this HBA can go only to specific slots) . So we are planning to move one of the n/w card to a free slot and put the HBA in that slot.
Is this going to affect the the n/w configurations any way ?
Do we need to do anything on the n/w side ?
Points assured .
Thanks/ James

Yes, this will have a significant impact on your networking -- it won't work anymore. The reason is that the LAN configuration is tied to the physical location of the card. You will have to use the console and reboot into single user mode (no networking) and make a note of the LAN device file name(s) with ioscan -knfClan. Then use rmsf -H to remove the LAN device files and kernel connections. Now shutdown -h to halt the system, power off, change the LAN card's location and add the HBA you need. Reboot the computer into single user mode again. Now if all goes well, the LAN card will be assigned the same device file (lan1 lan2 ...) on bootup. You can compare with ioscan -knfClan from before.
If true, then you can reboot into multi-user mode and you're done. If the device file has changed, you'll need to edit /etc/rc.config.d/netconf. Note that vi won't work in single user mode until you:
mount /var
mount /tmp
mount /usr
Once the LAN is reconfigured, you can reboot into multiuser mode. Using single user mode makes the changes easier.

Re: swapping the n/w card location
My suggestion is to take Bill's advice - you're not going to get any better!!
