However, looking at the Disk Model from your error description, there is a firmware 'NA02' available for this disk model. Hence, I would suggest to upgrade the disk firmware for this disk model X423_HCOBE900A10 --> go to NA02 and also get your data ontap up to the latest version (minimum recommended).
The NA02 drive firmware release for the HCOBE*A10 disk drive product contains the
following updates and improvements:
- Improvements in predictive failure algorithms to identify impending failures more accurately.
- Improvements in initial system setup to detect problematic disks.
- Improvements in Post SMART Trip to enhance write reliability.
Also, upgrade the Data ontap to - 8.2.5P5 (Which contains NA02 firmware)
