Symptoms

  The blinking Disk LED alternates between green and amber.
  The Data Domain Operating System (DDOS) does not post an alert for a related hard drive failure.
  Disk state is in normal status in DDOS.

DDOS does not post an alert for a related hard drive failure.

The disk has been identified for proactive replacement by underlying system infrastructures (for example iDRAC)

Resolution

Replacement steps for predictive fail hard drive:

  1. Verify the hard drive blinking LED alternates between green and amber.
  2. Collect the TSR logs to confirm the Predictive Failure.
    * Pred Fail (Predictive Failure) occurs in slot 3 similar to the example below.

  3. Verify that there are no disk reconstructions in progress before proceeding.
  4. Remove the predictive fail hard drive, Wait a few minutes for the system to recognize the disk has been removed.
  5. Insert a new hard drive.
  6. Verify that the disk becomes active and RAID reconstruction automatically starts on the newly inserted hard drive.


    Replacement steps for predictive fail on rear SSD:
  1. Verify the SSD health - blinking LED alternates between green and amber.

Physical Disks section in UI 

  1. Shut down the DD3300 appliance (Power Off)
  2. Remove the predictive fail SSD.
  3. Insert a new SSD.
  4. Power on and boot the DD3300.
  5. Verify that the disk LED status is GOOD.
    NOTE: There is no rebuild operation required as the SSD hosts the nvram emulation and DDVE data cache.
     The boot time may be a bit longer because the system takes time to use the new SSD.
