How can i automate to get the capacity values for centera cluster.

java -cp "C:\Program Files (x86)\EMC\Centera\4_3\SystemOperator\lib\CenteraViewer.jar" com.filepool.remote.cli.CLI -u admin -p centera -ip', " $centera_ip", ':3682 -script showcapacity.cli

where showcapacity.cli file looks like this:

show capacity availability

yes

yes

yes

yes

yes

quit

Do i have to create a file showcapacity.cli?

can you help me understand the syntax of the above command?

where will the output be saved?

thanks.

you have to install Centera Viewer tools on the system where you are going to run this script. CenteraViewer.jar is part of that install.

Yes, you have to create file sowcapacity.cli in notepad.  This file is basically issuie commands to Centera Viewer once connection is established.  Actually you don't need those multiple "yes" commands, but you do need the quit command. The output is send to standard out, i parse it on the fly in my perl script but you can also redirect it to a file and process it how you like.

java -cp "C:\Program Files (x86)\EMC\Centera\4_3\SystemOperator\lib\CenteraViewer.jar" com.filepool.remote.cli.CLI -u admin -p centera -ip', " $centera_ip", ':3682 -script showcapacity.cli  > centera.output
