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>
Warning
