Forklaring
Det cyc_fs filsystem bruges til at gemme supportmateriale, diagnostiske filer, og den plads, der forbruges af disse, administreres normalt automatisk. I nogle få sjældne tilfælde blev for mange støttematerialer bevaret, hvilket forårsagede, at ledig plads i cyc_fs var lav.

Brug brugergrænsefladen i PowerStore Manager eller Service Shell-scriptet svc_dc til at fjerne ældre dataindsamlinger for at frigøre plads i cyc_fs.
