Cause

Vid migrering av en komprimerad volym är det möjligt att mål-SDS tar emot migreringsdata som har trimmats helt eller skrivits med nollor. Om detta inträffar kan det hända att SDS inte behandlar data korrekt, vilket kan leda till att SDS startas om eller får panik. Det här är ett problem som kan uppstå under volymmigrering.

Resolution

Uppgradera PowerFlex till v3.6.1 eller v4.x och senare.
