smartctl test "Aborted by host"

[danzg]

I'm trying to run 'smartctl -t long' on all my disks.

Some of them then show 'Self-test routine in progress' when I do smartctl -a, but some of them show 'Aborted by host', even if I try to run the test again.

What does this mean?

Code:

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Aborted by host               90%        24         -
# 2  Extended offline    Aborted by host               90%        23         -
