smartd continues to write identical disk data for a failed drive

[Ulrich]

We had a SCSI drive failure in a HP Smart Array (cciss) during a long self test. The start of the test was logged, a temperature change was logged, too, but from then on each S.M.A.R.T request failed (because the disk died during self-test).
Amazingly smart continues to write identical smart values to the CSV file, and there's no indication that the drive is actually dead.
The version of smartmontools being used is 6.6 of SLES 12 SP4.

[Christian Franke]

Please provide the related (around time of failure) syslog and CSV outputs of smartd. If the drive is still accessible, please provide also a smartd -r ioctl,2 -q onecheck output.

or the easier part,I'm afraid this is not the information you are after:

"smartd -r ioctl,2 -q onecheck" seems to output an endless number of zeros:
