I would take a look into HP's APA product. It will allow you to create link aggregates or trunks of multiple ports. I would get the latest version from HP's software site. You'll have to make sure that your network switches are supported, which ones can be found in the admin guide. I've set up APA on 4 systems so far and its relatively easy. Mostly requires you and your network team to be on the same page. I don't see it on HP's site but do a web search for APA quick start guide. Other links below.

Hi,

follow below steps,
lanscan

decide which two lan interface you want to put in apa

both interface should be in same vlan.

verify link between to interface using command

# linkloop -i PrimaryPPANumber StationAddrOfSecondary

# vi /etc/rc.config.d/hp_apaportconf
HP_APAPORT_INTERFACE_NAME[0]=lan0
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR

HP_APAPORT_INTERFACE_NAME[1]=lan1
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR

vi /etc/rc.config.d/hp_apaconf
HP_APA_DEFAULT_PORT_MODE=LAN_MONITOR

# /sbin/init.d/hplm stop
# /sbin/init.d/hpapa stop
# /sbin/init.d/hpapa start
#lanqueryconf -s

more /etc/lanmon/lanconfig.ascii

verify lan interface entry is proper here

sbin/init.d/hplm start

lanscan -q

it shoudl show like

2
3
900 0 1

That config is for a standby lan card configuration.

If we speak of bonding, we want nics in and active/active configuration, so we get a big fat pipe.

take a look at the APA documentation, suggested in the above posts

Caveat Emptor:

You bond or aggregate (APA) 2 NICs to do either of 3 scenarios:

1. redundancy
2. aggregation (bandwidth increase or trunking)
3. aggregation+redundancy

BEFORE implementing one or the other - BE sure to check with your network persons (if separate fiefdom) that the switch infrastructure support such so they can set their end properly.
