APA Configuration Question

[cam9269]

Hi Guys,

Can you shed light on how this APA setup has been done, I'm a bit confused:

/etc/rc.config.d/hp_apaportconf contains:
HP_APAPORT_INTERFACE_NAME[0]=lan7
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR

HP_APAPORT_INTERFACE_NAME[1]=lan8
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR

When I do:
# lanadmin -x -v 900
Link Aggregate PPA # : 900
Number of Ports : 1
Ports PPA : 8
Link Aggregation State : LINKAGG MANUAL
Group Capability : 5
Load Balance Mode : Hot Standby (LB_HOT_STANDBY)

-- Does this mean LAN8 is the only member for LAN900?

Also # lanscan -q has the ff. outputs:
0
2
1
7
900 8
901
902
903
904

Saying to me that LAN8 is the only member of LAN900 - correct?

And I have this error during bootup:
Auto-Port Aggregation/9000 Networking*****************@#%
Tue Aug 04 EST 2009 16:41:06.958424 DISASTER Subsys:HP_APA Loc:00000
<1006> HP Auto-Port Aggregation product found that ports in failover
group lan900 are no longer connected to each other. Port 8 did
not receive any poll packets.

Please help. TIA!

hi,

check with linkloop and lanadmin if if your lan7/8 are connected to the switch.

in lanadmin the PPA number of lan should be UP - operational status.

Hi,

You have configured APA in "LAN MONITOR" mode with lan7 and lan8. But it looks there is no cable connectivity from lan 7. That's why it says "Port 8 did
not receive any poll packets" during startup.

For LAN MONITOR to work, all the ports to be connected to same subnet. You can check the connectivity using linkloop command.

Hi Guys,

Here are lanscan outputs:

-------------------------------------------------------------------------------

I can't do a linkloop on on LAN8 because it's not present in the lanscan outputs I sent earlier.

The question is, in the lanscan -v output above, under LAN900, it says LAN8 is UP. Does this mean that LAN8 is the only member of LAN900? Is there something wrong with my setup?

Regards.

Hello again guys,

I just got the lanadmin outputs, seems LAN7 is dead.

So I guess we need to replace LAN7?

[Alzhy]

Definitely. If your server is OLRADable -- meaning PCI/PCI-X are hot swappable -- then you need not shut down the system.

[rick jones]

I'm quite a bit rusty on interpreting lanadmin -g mibstats output, but if the only indication is the operational state being down, while it could be dead, it could simply be sleeping, or perhaps pining for the fjords... Checking the cable *and* the switch port to which lan7 is connected would be goodness as might running some online diagnostics against lan7.
