SNMP monitoring problem on P2000 G3 (MSA2312 iscsi)

Hi all,

i've a strange behaviour when i try to monitor with nagios via SNMP my new MSA2312 iscsi.

If i issue a single snmpwalk toward the box i get a correct answer, if i activate specific checks with nagios i get response timeout.
If i issue the same checks done by Nagios one by one they all succeed. It seems to me that if snmp gets are done sligthly more aggressive the box stops answering queries.

Anyone else is experiencing the same problem?
Unfortunately the only firmware available at the moment is the one already running on the boxes.

Best Regards, Roberto.

Hello,

the version installed on the box is attached below:

# show version
Controller A Versions
---------------------
Bundle Version: TS220R004
Build Date: Thu Sep 30 16:11:26 MDT 2010

Controller B Versions
---------------------
Bundle Version: TS220R004
Build Date: Thu Sep 30 16:11:26 MDT 2010

Success: Command completed successfully.

Making the same snmp query two times the 2nd after 30 mins than the 1st we got two different answers:

[root@vtlcmor5cp01 etc]# snmpwalk 10.0.0.2 -ccommunity -v2c -On .1 | grep "Overall Unit Status"
.1.3.6.1.3.94.1.8.1.3.16.32.128.0.0.52.50.48.49.54.55.0.0.25.4.0.0.23 = STRING: "Overall Unit Status"
.1.3.6.1.3.94.1.8.1.6.16.32.128.0.0.52.50.48.49.54.55.0.0.25.4.0.0.23 = STRING: "Overall Unit Status: OK"

[root@vtlcmor5cp01 etc]# snmpwalk 10.0.0.2 -ccommunity -v2c -On .1 | grep "Overall Unit Status"
.1.3.6.1.3.94.1.8.1.3.16.32.128.0.0.52.50.48.49.54.55.0.0.81.2.0.0.23 = STRING: "Overall Unit Status"
.1.3.6.1.3.94.1.8.1.6.16.32.128.0.0.52.50.48.49.54.55.0.0.81.2.0.0.23 = STRING: "Overall Unit Status: OK"

It seems that the MIB tree changes itself without any intervention on the configuration.

Hi,

 

I have the same problem on a dual controller iSCSI P2000 G3, firmware is TS220R004. The OID keeps changing. system/contact names etc and all <31 characters. It's driving me crazy and now the primary controllers has stopped responding on the web interface.... which seems to be a known problem.

 

Roberto, did you ever resolve your SNMP problem?

 

I am thinking of upgrading the firmwares to TS230P006.

 

Cheers

 

Ivan

Re: SNMP monitoring problem on P2000 G3 (MSA2312 iscsi)

I came up with a workaround. I wrote a a script:
snmpwalk -r:<ip address> -os:.1.3.6.1.3.94.1.6.1.6 -op:.1.3.6.1.3.94.1.6.1.6.255 –q

(http://www.snmpsoft.com/freetools/snmpwalk.html)

Which does a SNMP walk between:
1.3.6.1.3.94.1.6.1.6.0.0.0.0.0.0…..
to
1.3.6.1.3.94.1.6.1.6.255.0.0.0.0.0.0…..

There is only 1 entry:
1.3.6.1.3.94.1.6.1.6.x.x.x.x.x.x.x.x….. (the x’s are pretty random)
So there is only 1 output, hopefully:
3
Which means that all is well on the SAN. Another other than 3 indicates a problem. Using our management tool, I created a script to check this and am running it against both controllers.
