smartctl --offlineauto=on /dev/sda [-d TYPE] will not enable Auto Offline Data Collection
as reported by
smartctl -c /dev/sda
which shows
Auto Offline data collection on/off support
Auto Offline Data Collection: Disabled
no matter how I try to turn it on:
smartctl --offlineauto=on /dev/sda
SMART Enable Automatic Offline failed: scsi error badly formed scsi parameters
smartctl --offlineauto=on /dev/sda -d ata
Error SMART Status command failed: Input/output error

smartctl --offlineauto=on /dev/sda -d sat,16

SCSI device successfully opened
The drive is an SSD with Vendor "ATA ".
It is in smartctl's db.
It is in an mdraid.
Asking smartctl how it wants to talk to the device:
smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
smartctl --scan-open
/dev/sda -d sat # /dev/sda [SAT], ATA device
smartctl /dev/sda -d test
/dev/sda: Device of type 'scsi' [SCSI] detected
/dev/sda [SAT]: Device open changed type from 'scsi' to 'sat'
/dev/sda [SAT]: Device of type 'sat' [ATA] opened
smartctl -d TYPE /dev/sda
where TYPE is one of [ ata | scsi | sat | sat,12 | sat,16 ]
returns
TYPE device successfully opened

Edit: I found bug report for a similar issue on a similar drive:
"SMART status, attributes and thresholds cannot be read due to scsi error badly formed scsi parameters"
