APA on diffrent type of lan cards

We have purchased license for APA software with number recently from HP. We are planning to install and configure the APA this weekend. I am looking for a help to know whether my different kind of LAN cards will support APA. I have two types of LAN cards in my server on which we are going to implement APA. I would like to know whether APA will have any issue or difficulty in configuring APA between these lan cards. We are installing APA between LAN1 and LAN0 in which LAN1 is iether and other one is igelan.

I am unable to find any answer in APA Admin document about this. The doc only says devices whould have same operational characteristics.

Can any one please help me on this ?

Re: APA on diffrent type of lan cards

I have never encountered a problem with mixing ethernet cards,As long as they have the same speed, there is no problem.

What you can't have is a 100mb card with a gigabyte card
Windows?, no thanks

Re: APA on diffrent type of lan cards

Hi Sudheesh,
Most Important thing while going for APA config
both lan cards must have same speed or should be identical,

Please refer below procedure to configuration

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


vi /etc/rc.config.d/hp_apaconf

# /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

900 0 1

For verification you can also do using lanadmin command

lanadmin -r 0

then lanscan -q should show like

900 1

after few seconds it should come back as

900 1 0

Hope this solves ur query,

Re: APA on diffrent type of lan cards


If both interface speed is same then you can do APA.

Its not mandatory to have idenntical lan card.
