cd into the /usr directory and then do a 'du -ks * | sort -n' to look for the largest directory in /usr. Once you find it cd into that directory and do the du command again until you find something that can be cleaned up. It could be a large file in a directory or a bunch of smaller files that add up to a large amount.

Hi,

Welcome to the HP Community forums.

From your Facebook post in HP-UX, we see that /usr is 50% filled with the SAP installation.

Do you know if SAP is creating logs in /usr/SAP?

If true, what is the path to these logs?

Can you post the output from: vgdisplay vg00?

This will show if there is any unused space that you add to /usr.

If you deleted logs that were still open (modified recently), these files won't be freed until the program is finished.

You can use lsof to find files with "zero" links.
