opcragt (cleanstart question)

[Bearwhale]

Hey folks. Not sure if this is the right sub-forum, but I've been wondering whether there's a way to run the "cleanstart" command on multiple nodes in one command. Is there a way to create a list of nodes and run the "cleanstart" (or even "status") commands on that list?

Instead of typing something like:

opcragt -cleanstart node_name1

*Wait for command to finish*

opcragt -cleanstart node_name2

*Wait for command to finish*

opcragt -cleanstart node_name2

And so on...

is there a way to type a command like:

opcragt -cleanstart node_name1,node_name2,node_name3

To run cleanstarts on multiple nodes at once? Or even to run through a list of nodes and attempt to cleanstart them one by one?

If this is a silly question, I apologize. I'm a little new at this. I suppose I could try creating a batch file to do this but I'm not sure where I'd go with that either.

Thanks!!!

Hi Bearwhale,

Have you tried creating a tool to run the command?  This way you could run it on many nodes at one time.

Hey Brandy!

No, I haven't tried creating a tool. I guess that's my next step.

Do you know where I could find information about where to start with that?

Here's a quick JScript one that I've whipped up, haven't tested it though.

Chuck the below code into a file, name it something.js

then run it like this

cscript something.js node1 node2

Edited the code slightly

/*
Begin
*/
var wsh = new ActiveXObject("wscript.shell")

if(WScript.Arguments.length > 0) {
    intArgLength = WScript.Arguments.length
    for(args = 0; args < intArgLength; args++) {
        wsh.run("opcragt -cleanstart "+WScript.Arguments.Item(args))
    }
}
/*
End
*/

A really simple way to run commands to a batch of nodes is creating a text file with the list of nodes you want to process (one node name per line) and then running a one-liner using the "for" command on your Operating System command line:

For Windows:

FOR /F %variable in (FILE) DO command

example>

for /f %i in (node_list.txt) do opcragt -cleanstart %i

For Unix:

(as you type each line you'll get a secondary prompt allowing you type the next line in the script):

for i in `cat node_list.txt`

do

opcragt -cleanstart $i

done

Notice the backquotes on the `cat ....`

Hope this helps.

Thanks, everyone!!!

This gives me something to work with. I think I'll be able to make other batch commands off what you've given me.

Kudos all around!

Hi Bearwhale,

I created the tool and tested it and it works correctly.

This is from the system.txt after the tool was executed
