Symptoms

This KM is for multiple disk failures of  "SMART health-monitoring firmware reported that a disk failure is imminent." that are not related to the 'Hitachi 600/900GB Drive' issue outlined in Doc ID 2073735.1.

Reported against HGST-H7280A520SUN8.0T  and   HGST-H101812SFSUN1.2T  in ORACLE-DE2-24C and ORACLE-DE2-24P JBODS

The drives are reported as "faulted" in the hardware configuration.

FMA reports:

Fault class : fault.io.disk.predictive-failure

Description : SMART health-monitoring firmware reported that a disk failure is imminent.

 

BUT the disks are marked as "DEGRADED" in zpool status output (if you see "UNAVAILABLE"  then this is a "real" failure) and the drives are reported as :

c0t5000CCA2604AEEA0d0 DEGRADED too many errors
status: FMA has degraded this device.
action: Run 'fmadm faulty' for more information. Clear the errors using 'fmadm repaired'.

 

Then this document may apply to your case.
