number of physical network cards on the hpux server

[Shivkumar]

i want to count actual physical network cards on the hpux server. I mean i don't want to count virtual network interfaces. Just need to count actual physical one.

can anyone suggest me command for the same ?

Hi:

My first choice would be to do:

# ioscan -kC lan

...and if you simply want the count of LAN cards:

# ioscan -lc lan||grep -c lan

Regards!

[Mel Burslan]

ioscan -fnC lan | grep ^lan | wc -l

this gives you the number of network interfaces on your system. usually, lan0 is located on the system mainboard (there are exceptions to this rule rp4440 being one of them) so, if you subtract one from the obtained value, you can see your addtional network interfaces.

Also another caveat to the calculation above, the are dual or quad network cards, which means two or four network ports come on a single PCI card. In which case the number of cards and number of ports may not be one-to-one.

There is no straight correlation between the card count and the port count to make this calculation simple. Also, server type as in the case of rp4440/rx4440 goes, makes a difference on the card count.

Best bet is to know the server type and running a

ioscan -fnC lan

command and manually analyzing the output.

Hardware paths, if you look at their numerical representation, will tell you if you have a dual or quad network adapter cards.

For instance, on this system

# ioscan -fknC lan
Class I H/W Path Driver S/W State H/W Type Description
=========================================================================
lan 0 0/0/0/0 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX Core
/dev/diag/lan0 /dev/ether0 /dev/lan0
lan 2 0/5/0/0/4/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan2 /dev/ether2 /dev/lan2
lan 3 0/5/0/0/5/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan3 /dev/ether3 /dev/lan3
lan 4 0/5/0/0/6/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan4 /dev/ether4 /dev/lan4
lan 5 0/5/0/0/7/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan5 /dev/ether5 /dev/lan5
lan 9 1/12/0/0/4/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan9 /dev/ether9 /dev/lan9
lan 10 1/12/0/0/5/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan10 /dev/ether10 /dev/lan10
lan 11 1/12/0/0/6/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan11 /dev/ether11 /dev/lan11
lan 12 1/12/0/0/7/0 btlan CLAIMED INTERFACE HP A5506A PCI 10/100Base-TX 4 Port
/dev/diag/lan12 /dev/ether12 /dev/lan12

lan0 is built in lan and has a different path than the others.

lan2 thru lan5 as you can see is placed on the same h/w path, which tells you this is a quad card. And same can be said for the lan9 thru lan12.

This is how you get to calculate them.

Hope it helps

Try this script:

# cat /usr/local/bin/lancards

#!/usr/bin/sh
# script to check speed and settings of lan cards
PATH=/usr/sbin:/usr/bin
ppas=`lanscan | awk '$3~/^[0-9]$/{print $3}' | xargs`
for i in $ppas
do
printf "Card at PPA %s - " $i
ipa=`ifconfig lan${i} 2>/dev/null | awk '{ip=$2}END{if(ip==""){printf("Not assigned")}else{printf("%s ",ip)}}'`
printf "IP Address: %15s- " "$ipa"
lanadmin -x $i 2>/dev/null | awk '{$1="";printf("%s",$0)}'
echo ""
done

Shiv, You can use SAM to get to know how many network cards installed on your HP-UX server,

-Arun

[Shivkumar]

Is there a way to find out whether a particular "nic" has been configured for the backup purpose specifically ?

Regards,
Shiv

[Steven E. Protter]

Shalom again,

The primary network card is part of network configuration. You should be able to id it in /etc/rc.config.d/netconf

That's where I'd look.

I remember seeing the ability to designate a primary NIC in the Ignire install interface, perhaps that is what you refer to?

[Arunvijai_4]

Shiv, As Steve specified take a look at /etc/rc.config.d/netconf for all network configuration related information. Also, you can use #ifconfig -a to get all information.

-Arun

[Joseph Loo]

hi,

"lanscan" command will also tell u the number of network cards.

"netstat -in" will tell u the state of the cards.

regards.

[rick jones]

The difference between lanscan and ioscan includes:

*) lanscan will show APA aggregates

*) ioscan will show cards not claimed by a driver

FWIW, the being able to grep for "lan" may not be a 100% thing - third party devices _may_ not appear as "lan" devices in ioscan output. However, 99 times out of 10 grepping for lan is sufficient.

[Shivkumar]

Mel, If different cards are placed on the same hardware path then what is significance of this ? Thanks.

[Muthukumar_5]

It is not possible to assign same hardware path to different lan cards.

-Muthu

[Arunvijai_4]

Shiv, how is it possible to assing same hardware path to different NICs ? Wont you get a hardware conflict ?

-Arun

[Shivkumar]

Muthu and Arun; In the Mel's example above,
lan2, lan3 and lan4 are on the same hardware path.

could you please explain the same ?

[Arunvijai_4]

Shiv, what Mel specified is a Quad port card which contains 4 NICs together in one card and it can be assigned same HW path. It is used for fail over and load balancing. Its different from 4 individual NICs.

hi,

i normally use attached script which also gives me information on the speed.

e.g.
# ./lan-speed.sh
Card at PPA 0 - IP Address: 172.0.28.1 - Config = 100 Full-Duplex AUTONEG
Card at PPA 1 - IP Address: 192.168.14.1 - Config = 100 Full-Duplex AUTONEG
Card at PPA 2 - IP Address: 10.10.1.11 - = 1000 Full-Duplex. = On.
#

hope this helps too!

kind regards

HW paths are never "assigned" per se. Each bit of HW in the system has a specific path which reaches it. Each I/O slot has a specific HW path.

The HW path will include "path" information about internal stuff leading ot the PCI(X) slot, then PCI addressing information - PCI address and functional address.
