Disk Space Health

This is one of the things you might look at while trouble shooting Degradation, but in fact you ought to check it periodically, to avoid a problem developing and not being spotted. Doubtless someone may update this article to reflect improvements in IBM eServers in later models, but here is a rule of thumb used by folks on the older 400 models:

• The 400 needs a chunk of "unused disk space" for work, and if it runs out of work space, it can't do any more work.
• If you get to 90% disk space used, it is time to shut down your 400 until IBM delivers more hardware ... it is time for an emergency upgrade.
• If you get to 80% disk space used, consider this the red line ... either you fix what is eating up the disk space, or you order more hardware from IBM.
• If you get to 70% disk space used, consider this a WARNING ... you need to be taking steps to try to conserve disk space, or plan on buying more from IBM.
