APA - need help in configuring

[f. halili]

I have lan0 with IP www.xx.y.ZZZ. Just installed APA. And I'm going on cirlces configuring.

I have 4 LAN cards ( lan0 to lan3 ). How can I pair up lan0 & lan1 as an lan900? As of this time I only have one cable going to lan0, can I configure ahead before the other cable comes?

Thanks,
f. halili

Shalom,

Best practice is to have the cables connected, and the switch configured so the same IP address can span multiple ports. This is not the default on most switches and to change it after APA configuration is likely to disrupt the connection.

A lot of network admins' don't understand this so pull a doc from docs.hp.com and make sure they understand. If you are on a hub this is not an issue and you can probably proceed before connecting cables. APA should configure under those cirumstances.

are you looking for Port truncation means to achieve 100+100MB = 200MBPs throughput or network failover?

what is the output of lanscan -q; ioscan -fnClan

need to configure files in /etc/rc.config.d

hpbtlanconf, hp_apaconf, hp_apaportconf, netconf

based on your network card hardware, edit corresponding files to make them 100Mbps.

Very good documentation will help. For your other question, yes, cables first.

case with lan0 and lan1 are used
the interfaces should have the same configuration 'speed, duplex'
check switches : be carrefull trunks

## Mode Hot Standby

- conf => /etc/rc.config.d/hp_apaportconf

HP_ APAPORT_ INTERFACE_ NAME[ 0]= lan0
HP_ APAPORT_ CONFIG_ MODE [0]= MANUAL
HP_ APAPORT_ PRIORITY [0]= 5
HP_ APAPORT_ INTERFACE_ NAME [1]= lan1
HP_ APAPORT_ CONFIG_ MODE [1]= MANUAL
HP_ APAPORT_ PRIORITY [1]= 3

- conf => /etc/rc.config.d/hp_apaconf

HP_ APA_ INTERFACE_ NAME[ 0]= lan900
HP_ APA_ LOAD_ BALANCE_ MODE[ 0]= LB_ MAC
HP_ APA_ HOT_ STANDBY[ 0]= on
HP_ APA_ MANUAL_ LA[ 0]="0,1"


- conf file /etc/rc.config.d/netconf

INTERFACE_ NAME[ 1]= lan900 (lan900 remplace lan0)
IP_ ADDRESS[ 1]= â celle associée à lan0 précédemmentâ
SUBNET_ MASK[ 1]=
BROADCAST_ ADDRESS[ 1]=""
INTERFACE_ STATE[ 1]=""

- reboot.

- keet a connaection with console, a trouble could be possible in editing file!


- check apa :

- lanscan -q ( show 900 0 1) if ok

- ifconfig lan900

- netstat -i

- unplug the right link in order to check the use of the other link
lanscan lan900, give mac-address in order card

## Mode Lan Monitor:


HP9000

sw1 ----- sw2



- check 2 interfaces config speed/duplex

- conf => /etc/rc.config.d/hp_apaportconf

HP_ APAPORT_ INTERFACE_ NAME[ 0]= lan0
HP_ APAPORT_ CONFIG_ MODE [0]= LAN_MONITOR
HP_ APAPORT_ PRIORITY [0]= 5
HP_ APAPORT_ INTERFACE_ NAME [1]= lan1
HP_ APAPORT_ CONFIG_ MODE [1]= LAN_MONITOR
HP_ APAPORT_ PRIORITY [1]= 3

- no trunking on switches ports

- check linkloop is fine with 2 interfaces lan0 et lan1

linkloop -i 0 (mac-adress en 0x....)
linkloop -i 1

- create a config file lanconfig.ascii

lanqueryconf -s


- example /etc/lanmon/lanconfig.ascii

# ***********************************************************************
# *********** LAN MONITOR CONFIGURATION FILE *************
# *** For complete details about the parameters and how **
# *** to set them, consult the lanqueryconf(1m) manpage **

# ***********************************************************************
NODE_NAME xxxxxx
POLLING_INTERVAL 10000000
DEAD_COUNT 3
FAILOVER_GROUP lan900
STATIONARY_IP
PRIMARY lan0 5
STANDBY lan1 3

- Check the update:

lancheckconf

- create a failover group

lanapplyconf


- check the aggregate:

- lanscan -q

- netstat -in


By the way after fews test : the best way is for me use fail over method if you need agrragat, caus in other case the cost of aggregat could be higher than you expect gain. In fact if your chanel is not full use the cost to create the hash of the file is huge.
