[smartmontools-support] SMARTCTL NOT OK

[dinesh rajapaksha]

Hi ,

I'm using below HDD.
But it cause sudden restarts to server blade.

smartctl -a /dev/sda result is given below here. It shows SMART Health
Status: OK
But there are lots of uncorrected errors and delays.


Could you please let me know on what basis SMART Health Status become NOT
OK ?

This is as expected. A device does not return a failed health status if
(only) Read/Write error occured. It usually will return a failed status
if the number of spare blocks for reallocation is below some threshold.

Smartctl will report a non OK health status if the device firmware
indicates failure in ASC/ASCQ from SCSI IE log page (if supported) or in
result of REQUEST SENSE command (see -H on smartctl man page).

Thanks,
Christian
