Förklaring
Det cyc_fs filsystemet används för att lagra diagnostikfiler för stödmaterial och det utrymme som förbrukas av dessa hanteras normalt automatiskt. I några sällsynta fall behölls för mycket supportmaterial, vilket gjorde att ledigt utrymme i cyc_fs blev lågt.

 

Resolution

Använd PowerStore Manager-gränssnittet eller Service Shell-skriptet svc_dc för att ta bort äldre datasamlingar för att frigöra utrymme i cyc_fs.
