How can I check my systems to find out if they are clustered. I need to remane my two FAS 2020's. So if they are if fact clustered what is the process to rename them? Will I have to uncluster the system first? Will http://community.netapp.com/t5/Data-ONTAP-Discussions/FAS-2020-Cluster/td-p/51299 I also have to bring the systems down to remane? And how do I in fact remane the systems? Thanks much. Me too Reply 0 Kudos Options Bookmark Highlight Print Email to a Friend Report Inappropriate Content sinhaa Re: FAS 2020 Cluster 2011-05-30 09:22 PM Hello j2sysadmin, FAS2020 with ONTAP 7.2.6.1 can be in active/active cluster pair. To see if they are clustered, on CLI type command "cf status". It will tell you about the partner.f2050-yyyyy > cf statusCluster enabled, f2050-xxxxx is up. In this e.g. f2050-xxxxx is the partner of f2050-yyyyyBy rename I assume you want to change the hostname of the 2 storage systems. This will need you to run command "setup" on the storage systems and follow the steps. But this is a long task and will need you to set up everything.A quick way is:In the file /etc/hosts of the filer. Change the line that says localhost. Do the following on the storage system CLI.1. rdfile /etc/hosts2. Copy the contents to some notepad.3. edit the line.127.0.0.1 localhost
an expectation that you should, or even that you're going to be, reading or modifying files from the storage array's CLI. Files are meant to be accessed using a (surprise, surprise) file access protocol, such as NFS or SMB/CIFS, directly from a client. Having said https://erailine.com/2014/11/10/cli-file-editing-with-netapp-data-ontap-7-mode/ that, it can be useful to use the CLI to modify system files such as /etc/rc or /etc/hosts, particularly during initial setup or maintenance activities, and I've done it myself hundreds if not thousands of times. The biggest hurdle to overcome in CLI file editing is that there isn't a real editor included in the shell. Nope - no vi or Vim, no emacs, nano, or any other editor you may expect or like. There isn't even read error ed! Instead, file access and editing is done using rdfile to "read" or display the contents of a file, and wrfile to "write" the contents of a file. Rdfile is pretty straightforward - it's essentially just a cat equivalent that takes a file and sends it to standard output (your screen).

127.0.20.1 localhost-20 read error reading localhost-sk

And no, before you ask: there is no included equivalent of more or less (for paging of output), nor anything like tail or head. More's the pity. Wrfile, on the other hand, is a little different and less friendly. It does the exact opposite of rdfile - it takes standard input (the keystrokes/characters you type into the console/shell) and sends (writes) it to a file. This makes it very easy to create a file - as long as you don't make any typos! There is no interactive line editing with wrfile - if you make a mistake you're essentially starting over. Your best course of action is to create your text locally on your workstation with your tool (Vim, notepad++, etc.) of choice, and then paste it into your terminal window. After you've finished entering the desired content, make sure to hit Enter to be on a new line and then simply use Ctrl+c to end the input and terminate wrfile. If you aren't on a new line, any text already entered on that line will not be saved. Don't mind the "error reading standard input" - that's normal.
