[smartmontools-support] LOGICAL UNIT FAILURE PREDICTION THRESHOLD EXCEEDED

[Jean-Noel B. <jea...@im...>]

Hello all,

I get the following logs on a SCSI disk :

--------------------------
System logs :

sd 1:0:1:0: SCSI error: return code = 0x8000002
sdb: Current: sense key: Medium Error
     Additional sense: Unrecovered read error
Info fld=0x251af98
end_request: I/O error, dev sdb, sector 38907776
--------------------------

which is not "very" frightening ...

but

--------------------------
Smartctl logs :

SMART Health Status: LOGICAL UNIT FAILURE PREDICTION THRESHOLD EXCEEDED 
[asc=5d, ascq=2]
--------------------------

Would you please help me to get what "LOGICAL UNIT FAILURE PREDICTION 
THRESHOLD EXCEEDED" means.

Thanks.
