What does Cache Status LED on/blinking mean if HP MSA 2050 controller failed?
- R
  Renee GarnerSep 9, 2025
  If the HP Storage controller has failed or doesn't start and the Cache Status LED is on or blinking, it could mean the controller module isn't powered on. If you believe there's valid data in Flash, see Transporting cache; otherwise, replace the controller module. Alternatively, the system may have flushed data to disks. If the problem persists, replace the controller module.
