stor2rrd not "detecting" ISL ports correctly through BNA version 14.0.1

John

Hi,

I'm testing stor2rrd version 2.31-1 with BNA version 14.0.1 configured as/with:

It's only "picking up" ISL ports (2) correctly on 1 of 4 switches - on 2 other switches - it "picks up" only 1 of 2 ISL ports correctly - and on the 4th switch none at all. Everything else appears OK - any ideas..?? 


If I use "Non BNA" no issue.....

Hi John,

we know about this issue, but we can not do anything with this, because BNA REST API does not return all ISL ports. All ISL ports are available only via snmp.

Pavel

Hi,

can you try to restart of BNA services?

John

Hi Pavel,

Many thanks - yes - I have tried to restart BNA - unfortunately - this did not fix it.

John

Hi Pavel - just a thought on this - if I edit the ISL.txt files with the correct info - AND write protect them - how will stor2rrd "react" to this - I know - this would be quite a "hack".

Pavel

Hi,

well, we have experienced this already a few times.

BNA sometimes do not return correct ISL info (SNMP is always correct).

Your workaround might work, just comment out  getting ISL info in the BNA agent

bin/bnaconf.pl:115:

#
# ISL ports
#
message("CONF: Search for ISL ports : START") if $debug == 9;
#get_all_isl_info();
message("CONF: Search for ISL ports : END") if $debug == 9;

Hi Pavel,

Many thanks - this does actually work - and my ISL's are listed correctly.

However - it has not "fixed" another - apparently related issue - or so I thought.


I also have this issue for the ISL's regarding performance stats - as "individual ports" - the stats are displayed correctly - however - not as ISL's - my error log says - for example for each ISL port:

Could not find port2-46 file: /home/lpar2rrd/stor2rrd/data/BNE2-B-SAN384B-BNA//home/stor2rrd/stor2rrd/data/BNE2-B-SAN384B-BNA/port2-46.rrd /home/lpar2rrd/stor2rrd/bin/san.pl:1500

And log for cgi-bin for example:

totals:ISL:totals:san_isl_data_in_bna:9: no data yet: cmd file does not contain data source files: /home/lpar2rrd/stor2rrd/tmp/SAN-totals/san_isl_data_in_bna-y.cmd /home/lpar2rrd/stor2rrd/bin/detail-graph-cgi.pl:1554

The rrd files are actually "there" - and as mentioned - normal individual stats for the isl ports are ok.

If You have any idea's how this could be "hacked"...pls let me know.

Pavel

hi,

ok, lets wait for the end of nex week when Karel is back from his holidays, he is the developer of this part.

He will advice you.

John

Hi - no problem - many - many thanks for your help....

Karel

Hi John,

remove paths to rrd files in ISL.txt, let there only rrd file name instead full path.

Here is an example how ISL.txt should looks like:

port<port_ID>,<rrd_file_name>,<switch_name>-BNA,to_port=port<target_port_ID>,to_switch=<target_switch_name>-BNA

[stor2rrd@vm-karel data]$ cat brocade01-BNA/ISL.txt
port1-1,port1-1.rrd,brocade01-BNA,to_port=port1-1,to_switch=brocade02-BNA
[stor2rrd@vm-karel data]$ 
[stor2rrd@vm-karel data]$ cat brocade02-BNA/ISL.txt 
port1-1,port1-1.rrd,brocade02-BNA,to_port=port1-1,to_switch=brocade01-BNA

Hi Pavel - Arggh - I was thinking about trying that - but didn't get around to it - many thanks - that did the trick.
