Hi,

if you can reboot the server, them do it, if not you need tu restart the services, for APA,

If you are done editing all configuration modes, activate the
configuration by typing:
/sbin/init.d/hplm stop {optional--for failover groups}
/sbin/init.d/hpapa stop and then
/sbin/init.d/hpapa start
/sbin/init.d/hplm start {optional--for failover groups}

and if you check the

lanscan -qa and you see both adapters joined to the lan900 interface it sholud be working.

But actulay if I configure a server, I reboot the server and them test ping for example other server and disconnect a primary LAN interface for you LAN 0, and check if the APA is working.

hi,

the error is that you would like to bind to APA two diferent type of lan card.


and the lan0 is from core/IO, please try to

make APA configuration with a LAN1 <=> LAN2,

It's 4 port LAN card, so if this card failed the servers is without network, it will be better to have 2x 2 PORT cards.

I edited the hp_apaconf file & made the below changed, replaced 0,1 with 1,2

HP_APA_MANUAL_LA[0]=1,2

Stopped & started hpapa & found it is giving the error for port 1 now
