ServeRAID H1110 : How to tell which hard drive has a PFA from the SAS controller log - Lenovo x86 servers
Symptom
A Predictive Failure Analysis (PFA) originates in the hard disk logic and indicates a hard disk requires immediate replacement to avoid an outage. When a hard disk drive PFA asserts, the operating system's device driver passes that assertion message on to be recorded in the operating system's hardware event logs, the AMM logging, the IMM logging, the CMM logging, and MegaRAID Storage Manager logging.
With the ServeRAID H1110 SAS/SATA Controller, the message "hard disk predictive failure" will be posted in the logs. The message will not contain any content on the PFAing hard drive identification or slot identification information so the user will not be able to determine where the asserting PFA disk is located.
