MegaRAID Feature: Maintain PD Fail History
This KB article explains the 'Maintain PD (Physical Disk) Failed History feature that is in the LSI MegaRAID LSISAS2108 and LSISAS2208 based products.
Overview:
If enabled (the default), if a disk drive drops from a volume, it can not be used again in the volume with manual intervention in the event the drive comes back. Warning: See KB16511 regarding having this feature enabled with single drive RAID 0 volumes.

If disabled, if a disk drive drops from a volume (e.g. the cable gets disconnected) if the drive is redetected by the controller (e.g. the cable is reconnected), then the volume will automatically rebuild with the drive without any manual intervention required.
