V5000 storage no data in graphs

Leon

Hello together,

we would like to use STOR2RRD to monitor our storage infrastructure.

We have added 5 items to STOR2RRD so far:

2x EMC DataDomain

1x IBM SVC

2x IBM V5000

If we do the builtin connection test for those all checks return "OK"

Our problem is that the IBM SVC/V5000 is not shown under the "Health Status" tab.

Also Inside the "Storage" tree there are only entries for the DataDomains and the SVC, our V5000 systems are missing. (is this correct because they are managed by this SVC?)

Under the "SVC" entry all graphs have no data in them.

The data collection for the DataDomain is working great so far.

Does anyone know how we can fix that?

Best Regards

Leon

Hello,

Send us logs pls. 

Note a short problem description in the text field of the upload form.

cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir
tar cvhf logs.tar logs tmp/*txt
gzip -9 logs.tar

Send us logs.tar.gz via https://upload.stor2rrd.com

You might even attach screenshots when it helps in understanding of the issue.

Hi Leon,

there is a connection issue to your V5000. SSH connection must work without providing password.

Thu Nov 14 08:10:05 2019 - ERROR   - svcconfig.pl: ERROR: storage access is not working without providing password, this must work and role must be Administrator:
 - Return code: 1
Thu Nov 14 08:10:05 2019 - ERROR   - svcconfig.pl:        ssh lpar2rrd@xx.xx.xx.xx "lscurrentuser"

Follow this documentation:
https://www.stor2rrd.com/IBM-SVC-Storwize-XIV-DS8000-monitoring.htm
--> Copy ssh-key into the storage under storage superuse

After then try this connection test:

cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir
./bin/config_check.sh <Storage alias>

Let us know.

Leon

Hello Karal,

thank you so much, we found the error and now we are receiving data for all storages.

The issue was that the wrong ssh-username was set in the devicecfg.json file for the IBM storages.
/home/stor2rrd/stor2rrd/etc/web_config/devicecfg.json

The default user is stor2rrd but we created lpar2rrd users on the systems.

Suggestion for Improvement:
While adding the DataDomains via the webgui there was a field where you could specify the ssh-username, this field is missing when adding IBM-Storwize.
Maybe it would be possible to add it there?

Hi Leon,

there is "SSH username" for IBM Storwize family in the STORAGE device configuration.

Look at this example on our demo site:
https://demo.stor2rrd.com/?amenu=devices-storage&tab=undefined#
--> IBM-Storwize

Hello Karel,

this field seems to be missing in my installation (see screenshots)

I am using the virtual appliance in the version 2.60. Is it only availiabe in newer versions?

Karel

Hi Leon,

there was a bug in version 2.60. It is fixed in version 2.61.
