APA failover testing not working

sysad1_1 — Thu, 21 Oct 2010 04:56:53 GMT

Hi Gurus,

I have just setup an aggregate using my lan1 and lan8 iether NICs. Here's my current setup:

LinkAgg Name : lan900
LinkAgg Status : UP
Station Address : 0x0012799E692A
# Ports in Aggregate : 2
Configuration Mode : MANUAL
Distribution Algorithm : HOT_STANDBY
IP Address : xx.xxx.xx.xx (IP address was not shown intentionally)
Subnet Mask : xxx.xxx.xxx.xxx (Subnet was not shown intentionally)

I tried to test my bond or aggregate and see if failover works by disconnecting the lan cable attached to the either one of my NICs.

When I remove the connection from lan8, my network is still up so no problem with this. However, when I remove the connection from lan1 it is not failing over to lan8.

What configuration that must be done to achieve an automatic failover? Thanks!

Please identify your HP-UX version.

In HP-UX 11.31, it is recommended to use nwmgr to configure APA; in older versions, nwmgr does not exist and different commands must be used.

---------

If you're using HP-UX 11.23 or older, please show the output of these commands:

lanadmin -x -i 900
lanadmin -x -y 900

If you built the configuration by editing /etc/rc.config.d/hp_apaportconf, and have not rebooted after that, did you use the correct procedure to activate the new APA configuration?

/sbin/init.d/hpapa start
/sbin/init.d/hplm start

---------

If you're using HP-UX 11.31, please show the output of:

nwmgr -v -c lan900
nwmgr -S apa -I 900 -v

I have not rebooted after setting up my aggregate. My OS is HP-UX 11.11

# hostname
CCBDBPD1
# lanadmin -x -i 900
Link Aggregate PPA # : 900
Link Aggregation Mode : MANUAL
Load Balance Mode : Hot Standby (LB_HOT_STANDBY)
Active Port PPA # : 1
Port(s) ready : 8
Port(s) not ready : NONE

# lanadmin -x -y 900
Hot Standby = ON

Hi

Refer below steps,
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

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

LB_HOT_STANDBY requires specific Network Port Settings if I recall. Check with your Network Admin or the fiefdom who controls the Switches.

If you are only after NIC redundancy, follow the above procedure. LAN_MONITOR -- it should work.
