link aggregation config issues
I recently installed HP-APA on my HPUX 11.11i A-class system in order to gang the four ports on the installed A5506B four-port ethernet adapter and increase the available bandwidth to the server. However, when I enable the aggregated port, it works for about 60 seconds, then appears to shut down. There are no error messages that I can find, and everything appears to still be in place, but the network connection simply stops working. Rebooting causes the same behavior: works for 60 seconds or so after init completes, then appears to shut down. If I enable APA by hand, the aggregated port exhibits the same behavior. The ports are connected to a Cisco switch which my network admin has configured for APA. Any ideas where I might start looking?
I'm including my config files just as a check; hostnames and IP addresses have been changed to protect the guilty.
Thanks;
Jason

Re: link aggregation config issues
for the file...
/*--/etc/rc.config.d/hp_apaconf--*/
HP_APA_INTERFACE_NAME[0]=lan900
HP_APA_LOAD_BALANCE_MODE[0]=LB_MAC
would be...
HP_APA_INTERFACE_NAME[0]=lan900
HP_APA_LOAD_BALANCE_MODE[0]=LB_IP
Also, regarding the /etc/rc.config.d/hp_apaportconf file...
try renaming it to hp_apaportconf.try_without
See if that works...

Re: link aggregation config issues
We've got the following in each group in the ap_apaportconf file... I don't know if this is going to drop off your proc or not...
HP_APAPORT_PRIORITY[0]=0
So, our entries are more like (adjusted to be your example lan names) ...
HP_APAPORT_INTERFACE_NAME[0]=lan1
HP_APAPORT_GROUP_CAPABILITY[0]=5
HP_APAPORT_PRIORITY[0]=0
HP_APAPORT_CONFIG_MODE[0]=MANUAL
I was able to test the apaportconf file switcheroo in a planned downtime of a test server a while ago - but didn't get a chance to make a test with the AP_APA_PRIORITY[0] array uninitialized... probably works without it though...

Re: link aggregation config issues
This is my Data Protector cell server in a test environment, so I can do whatever reconfig and testing I like during the day. So, I was able to test your recommendations.
The hp_apaportconf file does need to be in place. The HP_APAPORT_PRIORITY config option is used for hot backup port configs, and when I had it in place, I saw noticeable errors (dropped packets and such), so I removed it. However, dropped packets is better than no packets, so I may put it back in place to test further tomorrow.
What I find especially odd, though, is that after ping stops responding, if I run netstat -in repeatedly, both Ipkts and Opkts keep increasing. I assume I'm reading this correctly, and that means "incoming packets" and "outgoing packets".
Thanks,
Jason

This is an L class server. It looks like some slots APA isn't supported in. By chance do you have a card in a slot it doesn't support?
We don't have APA on this server. So this error is more of a OS error.

Re: link aggregation config issues
I think the problem is due to mismatch of switch and server configuration. Please check with the switch admininstrator what fec (Fast EtherChannel of Cisco)mode the switch ports are set. I suspect it is auto, which means the switch ports are running PAgP aggregation protocol.
To match that, you should set the port mode of server to FEC_AUTO in hp_apaportconf file.
Please change all lines of
"HP_APAPORT_CONFIG_MODE[{1,2,3,4}]=MANUAL" to
"HP_APAPORT_CONFIG_MODE[{1,2,3,4}1]=FEC_AUTO".
Important note: do not change the line for lan0( HP_APAPORT_CONFIG_MODE[1]=MANUAL), "otherwise your core lan may be aggregated, and you may lose site-lan connection.
In hp_apaconf file, you should remove the following line:
HP_APA_MANUAL_LA[0]="1,2,3,4".
Load balance alogrithm is NOT releavant to your problem.
HTH,
Xianjie
P.S.: Cisco switches use different names for port mode. "On" is equivalent to "MANUAL".
"Desireable" is equivalent to "FEC_AUTO".
If you are using new Cisco switches, it also supports LACP. Ask your switch administrator if LACP is used for those ports.
IF LACP is used, then the mode of lan1, 2, 3 and 4 should be set to "LACP_AUTO".

Re: link aggregation config issues
Xianjie, thanks for the input. I spoke with my network admin, and he said we're not using Fast Etherchannel, because it is incompatible with the private vlans we use. The only configuration done on the APA ports at the switch end is to force 100FD and set the ports to promiscuous mode (because these are being used by a backup server on an admin LAN).
Is it possible that APA is incompatible with private vlans?
Thanks;
Jason
