how do I add netapp systems to the dfm server without discovering the whole subnet? I want to do it by selectively entering the ip addresses of the systems

you can add individual storage systems wit the command "dfm snmp add -m 26 -v "snmp_version eg:1" -c "ro community of NetApp Filer" "Filer IP Addr"

Hi TDUBB1234

You can do it via the CLI using:

dfm host add <hostname | IP Address>

or

via the GUI

> Click on the Control Center Tab

> Home

> Member Details Tab (In Group Summary)

> At the bottom you should see a dialogue for Add New Storage System

Enter your IP Address or Hostname there

Kind regards

Rich

how do i disable the scanning of the whole subnet?

Scanning of Subnet happens only wen you initiate it...

its a brand new dfm server installed. I think by default it scans the entire subnet on intervals. I want to disable that and only add the ip addresses of the storage systems

do I have to change the trap locations on the systems to the dfm server?

"dfm host add -N ip-address" will add the host but will not add the subnet (and thus avoids scanning the subnet).

If you add the host using NMC, that also avoids adding and scanning the subnet.

Do the following steps to resolve the issue

1. Check the ro community group in the filer by running the command "snmp"

  1. Add an "SNMP Community String" on the DFM end to match the counterpart on the storage system:

run dfm snmp add -m 26 -v "1" -c "Community_on_Filer" "Filer_IP"

3. Check the snmp connectivity in dfm server by the command

dfm host diag "filer IP"

You need to set the username and password for the storage system you are using.

You can do so by executing the following command on the dfm server: dfm host set <filer IP> hostLogin=<username> hostPassword=<password>

I have the correct password but in ops manager I am seeing this

Adding a Storage System to DFM:

1. The snmp community set on DFM should match that on storage system.

On DFM:

    10:~ # dfm snmp list

    \ID   Address                                    Prefix Length  Pref SNMP Version  Community  Auth Protocol    Login            Privacy

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

    1    default                                                   SNMPv1             public

    If there is an entry like this, by default, Storage systems would be discovered using public community string.

On Storage System:

    $ snmp

   contact:

    location:

   authtrap:

            0

    init:

             1

    traphosts:

        fd20:8b1e:b255:40b8:20c:29ff:fe07:55ca (fd20:8b1e:b255:40b8:20c:29ff:fe07:55ca) <fd20:8b1e:b255:40b8:20c:29ff:fe07:55ca>

        10.72.186.77 (10.72.186.77) <10.72.186.77>

    community:

         ro public                                                                            <------------------------ This is the community string which should be set in DFM

For our current setting in DFM (the above one) we are good.

Else, make a specific snmp entry for the desired storage system by

     dfm snmp add [ -m mask ] [ -v prefsnmpVersion ] [ -c communityName ] <address>

e.g 10:~ # dfm snmp add -m 32 -v 1 -c public 10.72.184.201                  <------------------------------------ -m 32 means, ONLY the community string used for this system would change. Else if the subnet mask of the subnet is specified, DFM will start using this new community string for all systems and since the other systems may have different community strings, monitoring may fail for them. (like you've specfied above in you reply: SNMPv1                 Failed: Timeout )

Added addr: 10.72.184.192, prefixlength: 32, prefsnmpVersion: 1, community: public.

Now:

    dfm snmp list

ID   Address                                    Prefix Length  Pref SNMP Version  Community  Auth Protocol    Login            Privacy

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

2    <IP address>                              32 bits           SNMPv1             public

2. Add storage system.

    dfm host add <IP address>    <-------------------The complete network where this IP belongs would also be monitored

    dfm host add -N <IP address>     <--------------The network where this IP belongs would NOT be monitored

    The system should get added and 'dfm host diag' sgould give the following entry now:

        SNMPv1                 Passed

3. Set the credentails using:

    10:~ # dfm host set <IP address> hostLogin=<username> hostPassword=<password>
