A smartd warning email only mentions the /dev/ice name. It should also include device ID, S/N and WWN.

File scsiata.cpp contains comments claiming that it supports fixed format response to SCSI request sense command (response code 0x70 and 0x71). Indeed, the implementation of sat_device::ata_pass_through() parses such responses correctly and returns true. However, it does not fill the descriptor buffer (adrp). Function smartcommandhandler() in atacmds.cpp calls sat_device::ata_pass_through() and fails if descriptor values are absent, specifically lba_high and lba_mid. It is not clear to me how this should be fixed:

1. Use a different logic when fixed format is returned (instead of checking lba_high and lba_mid),
2. Or, issue SCSI request sense command with the DESC bit set, which would force the descriptor format. As that may cause problems with older devices, perhaps a parameter should be introduced, settable in drivedb.h.

User-visible symptoms of this bug are:

1. smartd refuses to monitor the affected drive, producing an error such as: "Device: /dev/sdd [SAT], not capable of SMART Health Status check"
2. smartctl shows SMART info correctly, but with a complaint: "SMART STATUS RETURN: incomplete response, ATA output registers missing"

This problem was noticed with external USB drive: WD MyPassport 2TB (WDBY8L0020BBL), USB: 1058:0748

Querying the info for a physical device using:

$ smartctl --info /dev/bus/0 -d megaraid,7
# OR
$ smartctl --info /dev/bus/0 -d megaraid,7 --json

yields different results - specifically, the JSON output lacks the following object:

  "smart_support": {
    "available": true,
    "enabled": true
  }

even though the human-readable output reports the support is available:

$ smartctl --info /dev/bus/0 -d megaraid,7

Might be due to the following error produced by using --log=error flag:

"local_time": {
    "time_t": 1734663658,

Additionally, there is an inconsistency the other way around:
