Dell Equallogic PS4000 SAN SNMP Error

[suuruu]

Dear Support,

I have a problem with adding Dell Equallogic to Devices in Cacti. I tried add it with snmp v2, but cacti replied SNMP error. The snmp setting are good, because PRTG can check the SAN.

Could you help me, what is the problem with these settings?

Thank you,
Janos

Yes that's what I thought too but think that its left blank for security reasons
Add a description to your SAN.

In that case, we need an

snmpwalk -c public -v 2c <hostname/IP> system

I am sorry, but I deleted it from the picture, perhaps I set the SAN's IP address. I have several devices, switches, routers, servers working in Cacti with snmp v2c.

Any suggestion?

Thanks,
Janos

Dear gandalf,

I attached the output of your suggested command.

Thank you,

I feared that. Empty sysDescr.
Two approaches:
1. Enter a valid sysDescr in snmpd.conf or wherever on that target device
2. change cacti code to not use sysDescr but sysName or whatever (we are using the ASN.1 numeric representation)
Currenty, we have no "settings" to select which OID shall be used for device detection; so this will be a custom patch.
I'm able to create that patch in case you prefer this method.
Please be aware of the fact, that YOU will have to maintain that patch across releases ...

Connect a browser to your SAN group IP and login using an admin account. In my environment a java applet will start which will let me modify the settings of the SAN. Find the SNMP settings tab and you'll see that you don't have a 'description' set. Set it to something meaningfull or '.'. Any char string will do.
Then you'll be able to use it from Cacti.

And where need I set any char to use successful my SAN with Cacti?

Are you asking where in the java applet interface you need to be to change the snmp settings?
Don't know from memory but the interface isn't that complicated that you can't find it.

Login with your grpadmin account and click on 'Members', on the right side you'll get a list of your members. Right click in turn on each member and select 'modify member settings'. In the popup window add a description and press OK. If you have done that for each member then it should be possible to query using SNMO
