Issue with the Lenovo V3700V2XP (8.2.1.9)

WoLFeNT

Hello,

I found an issue with the Lenovo V3700V2XP.

I use STOR2RRD version 2.70-1.

1: old hosts and host cluster object showed and no really present hosts showed
--------------------------------------------------

This storage never monitored by STOR2RRD.
The storage had an old configuration: I wiped it and installed the latest software (8.2.1.9 of 06-02-2020).
I configured it and enabled monitoring on STOR2RRD.

Now STOR2RRD show old host and host cluster that are not present and do not show the real host present (no host cluster is defined).

I tried to erase V3700V2XP dump folder, where allowed, and erase all STOR2RRD storage data, but nothing changed.

2: error on all SSH session disconnect
--------------------------------------------------

This error are reported for all SSH session:

error.log-DS211
Sat Mar 21 15:25:43 2020 - ERROR   - svcperf.pl: Unable to disconnect from remote machine

output.log-DS211
Sat Mar 21 15:25:43 2020 - INFO    - svcperf.pl: Process IOSTAT files - Time: 200321_152339  Nodes: 2
Error: Can't locate object method "disconnect" via package "Net::OpenSSH" at /home/lpar2rrd/stor2rrd/bin/SVC.pm line 2078.


Can you help me to fix ?
Best regards.

Hi,

1.

host configuration is refreshed in stor2rrd once a day for this kind of storage (Storwize)

Is that more that 24 hours already since changes?

2.

cd /home/stor2rrd/stor2rrd

. etc/stor2rrd.cfg
$PERL -MNet::OpenSSH -e 'print "Version: $Net::OpenSSH::VERSION\n"'

Hi Pavel,

1.

The storage was insert on STOR2RRD with its definitive setup on 15-march.

2.

Version: 0.62

Regards.

Pavel

2. I suppose there is installed module like this:

perl-Net-OpenSSH-0.62-1.el7.noarch

remove it byt: rpm -e perl-Net-OpenSSH-0.62-1.el7.noarch

Then will be used module from /home/stor2rrd/str2rrd/lib/Net/OpenSSH which is newer.

let us know if that resolves it.

Ok, now seem fixed !

Pavel

1. it looks fresh, is information inside correct?

cat data/<storage>/HOST/hosts.cfg

WoLFeNT

No, the hosts are old and not present on the storage.

cat data/DS211/HOST/hosts.cfg

HQW-VCS10 : 0000 0001 0002 0003 0004 0005 0006 0007 0008 0009 0010 0011 0012 0013 0014 0015 0016 0017 0018 0019 0020

this one looks actual: data/DC-DS20/svc.config.cron.xml_78E02E9-1

this is provided by the storfage, edit it and check if there are such hostanmes, they will be there

If so then storage reporting them to us. It must be a storage issue the.

WoLFeNT

Sorry Pavel,

I confused storage in my reply of 21-March for this request:

----------------------------
date
cd /home/stor2rrd/stor2rrd
ls -l data/<storage>/HOST*/
ls -l data/<storage>/*xml*
----------------------------

The correct report is this (taked yesterday):

-rw-r--r-- 1 lpar2rrd lpar2rrd 475 Mar 23 18:15 hosts.cfg-old

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

So I downloaded the file 'data/DS211/svc.config.cron.xml_781FA33-2' from STOR2RRD appliance and I open it.

There is no entry for this old hosts and there is the correct host that STOR2RRD not showing.

Strange: the file aquired by STOR2RRD is correct !

However I checked the dumps folder on the storage DS211 and I found that on the node1 there are 2 configuration file:

svc.config.cron.xml_781FA33-1
svc.config.cron.xml_781FA33-2

781FA33-1

is an old file (time and date old) that report an old configuration.

781FA33-2

is current configuration file (with recently date and time) and report the correct configuration.

Unfortunately file *svc.config* cannot be deleted...

Do you think I have to open a case with Lenovo support ?

Regards.

Pavel

no this is not a problem, looks like it is not processing new xml file, latest processed is

data/DS211/svc.config.backup.xml.check from 15th of March.

I suppose there is still old configuration.

send us

tar cvf d1.tar data/DS211/*xml* logs/*DS211

gzip -9 d1.tar

https://upload.stor2rrd.com

refere to this case

Hello Pavel,

I sent the requested files.

Regards.

WoLFeNT

Hello Pavel,

I sent the requested files as simple zip file. 

The stor2rrd acquire the old and the new configuration file present on the storage and I think it use the old file.

Regards.
