ping from ssh not recognized

MIKOFLYZONE — Wed, 25 Jun 2014 15:47:54 GMT

Hello,

I have a problem that I think was already discussed but I'm unable to find it in older posts.

The ping command works just if I'm direclty connected to netapp, it I executed by passing the command to ssh is not working.

Did you know how to solve this problem? I would like to check the connection on the Disaster Recovery site directly on netapp,

without the need to check the snapmirror status...

Thanks.

See below the example:

BASH-myuser@myserver.rpc.intra /home/myuser# ssh root@fas2

fas2> ping fas4

fas4 is alive

fas2> exit

logout

Connection to fas2 closed.

BASH-myuser@myserver.rpc.intra /home/myuser#

BASH-myuser@myserver.rpc.intra /home/myuser# ssh root@fas2 ping fas4

ping not found. Type '?' for a list of commands

BASH-myuser@myserver.rpc.intra /home/myuser# ssh root@fas2 help

? file nfs snap

acpadmin flexcache nfsstat snaplock

aggr fpolicy nis snapmirror

autosupport fsecurity options snapvault

backup ftp partner snmp

bmc halt passwd software

cdpd help ping6 source

cf hostname pktt sp

BASH-myuser@myserver.rpc.intra /home/myuser# ssh root@fas2 priv

admin

BASH-myuser@myserver.rpc.intra /home/myuser# ssh root@fas2 sysconfig

NetApp storage ping fails

senthilj — Mon, 02 Nov 2015 11:21:18 GMT

Hi Guys,

We have a NetApp filer whicch is running pretty old ontap version 7.1. I have not been able to ping the storage and cannot login via ssh or telnet. All the shares both cifs nad nfs have lost access to the data. I someohow was able to login to the filer via Serial COM port and did basic test and found the network cards e0a and e0b are up and fine. We have configured vif with both of these interfaces.

Any help to fix the issue is much appreciated.

Thanks

Faisal

Hi, Did you get a chance to look at the ouput I have provided as requested by you?

Re: NetApp storage ping fails

RPHELANIN — Wed, 11 Nov 2015 09:07:21 GMT

yes and it looks fine, do you have any vlans on your network?

Re: NetApp storage ping fails

senthilj — Wed, 11 Nov 2015 10:31:47 GMT

Yes, we do have VLANs in our network

Re: NetApp storage ping fails

RPHELANIN — Wed, 11 Nov 2015 10:54:11 GMT

if those vlans are used by hosts accessing the data then you need to add them to the rc file

Okay, I shall do that. First thing I should be able to ping the filer and able to access the filer via putty ssh or telnet which I am unable to. Currently I am able to access only via serial comm port.

It's certainly weird behaviour, but it does work if you run "priv set diag" first e.g. ssh myfiler "priv set diag; ping myhost"
