Control Station constantly pinging "echo" command (VNX and VNX2)

Also, my bad this replication is from VNX5700 to another VNX5700.

@Ernes

- by doing "unalias echo", would that impact any existing setting (Replication) on either VNX?

- and, more importantly (read: curiously), why is this 'suddenly' happening?

i definitely don't see this on my two VNX5700. Is it in root's history or nasadmin ?

Ignore the unalias command since i misunderstood your question. You don't have an alias created for echo

@Ernes - no worries thank you for checking and clarifying.

@Dynamox - this is output when i log in, so i assume this is under the "root" directory. I do login as 'nasadmin'. Not sure if that answers your question (?)

Output of ALIAS below:

[nasadmin@xxxxxxx ~]$ alias

alias groupadd='echo Please use EMC Unisphere for User/Group management.'

alias groupdel='echo Please use EMC Unisphere for User/Group management.'

alias groupmod='echo Please use EMC Unisphere for User/Group management.'

alias l.='ls -d .* --color=tty'

alias ll='ls -l --color=tty'

alias ls='ls --color=tty'

alias useradd='echo Please use EMC Unisphere for User/Group management.'

alias userdel='echo Please use EMC Unisphere for User/Group management.'

alias usermod='echo Please use EMC Unisphere for User/Group management.'

alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'

Run the following command on the control station and paste the output: alias

It's nasadmin based on the output he provided. I checked on my VNX as well and don't see it as well. Try a control station reboot and see if that solves it.

[nasadmin@CONTROLSTATIONNAME~]$ history

One more thing. If you see the echo command when you run the above command then you can simply unalias the echo command. Just run: unalias echo

hi Dynamox,

Don't want to keep it lengthy, but here's a snippet from the Control Station. Its a VNX5700

I just saw your reply to dynamox and I misunderstood what you were asking. I thought that you said whenever you run an echo command a ping is being issues.

I haven't sen this one before. Rebooting the control station is the only thing I can think of. Won't impact anything and the other control station will become primary.

can you post a screenshot of what you are talking about ?

hmmm. not sure.

We do have a Monitoring team that use tools like NetCool / Nagios for monitoring (incorporated with TACACS). But that should not necessarily generate a echo every few seconds / minutes (at least this obviously from the CS - correct?)

understood, do let us know what kind of gremlins you find in your CS

OK. I will see if that can be done within EOD today, if not, will do it and come here and provide and update.
