APA and LAN monitor configuration problem: set_config_mode: failed, errno is 34

[Olga_1]

Hello,

I configured APA: lano and lan2 are grouped into lan900 and configured using FEC_AUTO mode and lan900 and lan1 are grouped into lan901 for failover using LAN Monitor.

When I reboot the server I get the following in rc.log:

Configure HP AUTO-PORT AGGREGATION interfaces

Hi,

[1]
You don't need to set the Mode for Link Aggs.
So, the line in config file that sets the Mode of 900 to LAN_MONITOR is not needed, you can remove it. This causes you to see errno 34.

[2]
After system boots up completely, do you see the configuration as intended? I guess so! But you are just worried about this errno 34. Is that right?

[3]
The warning of failed link-level connectivity may be seen as link agg 900 - which is FEC_AUTO mode linkagg, may not have been completely created as auto negotiation may take a while. But this is just a warning to let you remind to check connectivity after the system boots up completely.

Hope this clarifies..
Let me know if you have further questions.

Thank you very much, Ketan.

Please confirm that this is how hp_apaportconf file should look like:
Should I comment out
GROUP_CAPABILITY and PRIORITY for lan901 as well.

HP_APAPORT_INTERFACE_NAME[0]=lan0
HP_APAPORT_GROUP_CAPABILITY[0]=900
HP_APAPORT_CONFIG_MODE[0]=FEC_AUTO

HP_APAPORT_INTERFACE_NAME[1]=lan2
HP_APAPORT_GROUP_CAPABILITY[1]=900
HP_APAPORT_CONFIG_MODE[1]=FEC_AUTO

HP_APAPORT_INTERFACE_NAME[3]=lan900
#HP_APAPORT_CONFIG_MODE[3]=LAN_MONITOR
HP_APAPORT_GROUP_CAPABILITY[3]=901
HP_APAPORT_PRIORITY[3]=5

HP_APAPORT_INTERFACE_NAME[4]=lan1
#HP_APAPORT_CONFIG_MODE[4]=LAN_MONITOR
HP_APAPORT_GROUP_CAPABILITY[4]=901
HP_APAPORT_PRIORITY[4]=3

[2]
lanscan -q

901 900(0 2) 1

Thanks again for your help.

Hi,

You may want to change the following:
HP_APAPORT_INTERFACE_NAME[3]=lan900
HP_APAPORT_GROUP_CAPABILITY[3]=900
HP_APAPORT_PRIORITY[3]=5

HP_APAPORT_INTERFACE_NAME[4]=lan1
#HP_APAPORT_CONFIG_MODE[4]=LAN_MONITOR
HP_APAPORT_GROUP_CAPABILITY[4]=901
HP_APAPORT_PRIORITY[4]=3

TO the following:
HP_APAPORT_INTERFACE_NAME[3]=lan900
HP_APAPORT_GROUP_CAPABILITY[3]=900
HP_APAPORT_PRIORITY[3]=5

HP_APAPORT_INTERFACE_NAME[4]=lan1
HP_APAPORT_CONFIG_MODE[4]=LAN_MONITOR
HP_APAPORT_PRIORITY[4]=3

This will yield the intended configuration without any errors!!

GroupCap of lan0, lan2 and lan900 should match as you want lan0 and lan2 to "JOIN" lan900.

All Link Aggs are in LAN_MONITOR and cannot be changed in that sense.
lan1 should be set to LM since it has to be added to create lan901.
Setting GC to 901, 900, and 1 does not matter for creating LM FOG.

Thanks and regards,
