about the MIB files for VNX

Question

hi, I have a question about MIB files for VNX..

As per emc171987, there is no new MIB for the VNX Series. The CLARiiON FA MIB is still valid for use with the Block portion of VNX.

VNX for File has a MIB and supports SNMP v1 , v2, and v3 (/nas/sys/emccelerra.mib).

here are my questions:

1) I downloaded the MIB as per the link of emc171987 but the MIB file seems very short and like a empty template. I don't see any OID from the MIB file as what I saw from Data Domain MIB files which includes a lot of OID.

and I get a OID for VNX(block) from the forum(I don't remember the link) but it works!

[root@lx0034nbumast bin]# snmpget -v 2c 10.119.9.121 1.3.6.1.2.1.1.1.0 -c activenetwork
SNMPv2-MIB::sysDescr.0 = STRING: VNX7500 - Flare 5.31.0.0.5.704

So I am wondering where I can get the similar OIDs for CX4 or VNX(block) ?

2) VNX for File has a MIB under /nas/sys/emccelerra.mib. but it is also very short and like a empty template. I am wondering where I can get the similar OIDs for VNX(File) or VG2 ?

please help point me the right direction...thanks in advance!

The MIB for file (data mover) just mentions the EMC additions – which isn’t much

The SNMP on the data movers also supports the standard MIB-II – mostly IP information about the interfaces

That’s all there is

Ah, I see. It should be datamove IP , not control station IP since SNMP is running on datamover not control station....

Hehe, yeah you caught it seconds before I responded.

ivyyang, What you have configured is SNMP on the data movers.  Therefore, you should be running the SNMPGET on a public IP that you assigned to the data mover and not the control station.

ivyyang1 · Answer

it seems not good news... I can retreive info via Navisphere CLI for VNX block...............the headche is vnx flie or VG2......

besides...the SNMP on the datamover is running but when I try the SNMP commands it always prompt "no response from...." there is no firewall blocking since all the IPs are in the same network section.......

.[nasadmin@lasvnx01cs1 ~]$ server_snmpd server_2 -service -status
server_2 :
SNMP Running
[nasadmin@lasvnx01cs1 ~]$ server_snmpd server_2 -modify -community public
[nasadmin@lasvnx01cs1 ~]$ server_snmpd server_2 -info
server_2 :
enabled = Yes
location = system location is not set.
contact = system contact is not set
community = public

[root@lx0034nbumast ~]# snmpwalk -v 2c -c public controlstation_IP
Timeout: No Response from controlstation_IP

haha  you're right.....I was aware of that just now...please look my replies above anyway thanks!

As a consequence of its linux roots, the control station can also be polled.  Simply via the standard /etc/snmp/snmpd.conf configuration file and corresponding snmpd (/etc/init.d/rc.d/) service which is stop 'd by default.

thanks for the reminder Christopher !

Rainer_EMC · Answer

The control station snmpd will only have the control station info though – just its own network interfaces and CPU/memory It doesn’t cover anything on the data movers or storage processors

ivyyang1 · Answer

Thank you Rainer!&#xa0; I tried to modify the /etc/snmp/snmpd.conf and define the OID myself and then I can get whatever I want!&#xa0;

Rainer_EMC · Answer

Yes – but within reason please

Don’t try to fork of lots of commands that bring down the CPU / memory.

Some of the performance stats for example start a Java process every time – if you combine that with a SNMP monitoring app that polls hundreds of these every few minutes you won’t be happy

Ah I was not aware of that it will bring down CPU/mem and may have performance issue, thank you for the reminder!

but I tried to get the output of the following commands via SNMP since we need get report for storage, for example to get the filesystem utilization, pool utilization, hardware status(batterry,data mover, shelf...........) ........

I don;t run performance stats.....

will these commands start a Java process ?

nas_environment
nas_fs

nas_inventory

nas_pool

server_checkup cifs

server_checkup nfs

server_uptime

Rainer_EMC · Answer

Normally not – you need to check

Avoid server_stats – it definitely does

Obviously avoid starting skripts that can block or never end

Also read the scripting guidelines – they should be in the appendix of the VNX file reference manual for some other tips

Like for example – if you can use –query facitity it is less load on the CS

ivyyang1 · Answer

thank you  very much! Rainer....I don;t need to run any *stats commands...........
