Hi,

I've attached a patch that allows smartctl to access SATA drives on LSI 3ware 9750 controllers.

I've been using this version on multiple systems (with 3ware 9650, 9750, and on-board SATA and SAS only) for almost a month without any problems.

Please let me know if I need to make changes and re-submit it again, or if there's a different procedure for submitting this patch.

Regards,

Victor

For scheduled selective self-tests, smartd reads the last test span from the selective self-test log of the drive. At least some WDC drives reportedly do not preserve the self-test log accross power cycles, see ​smartmontools-support list.

To support such drives, smartd should store the last test span in its state file instead.

Smartctl and smartd assume that the old SMART error log (log address 0x01) is supported if an error-logging capability bit in IDENTIFY or SMART data is set. Same applies to old SMART self-test log (log address 0x06). These logs were introduced in ATA-5 and are now outdated because 48-bit LBA addresses are not supported. Recent devices may only support the newer 48-bit capable logs (extended comprehensive error-log, extended self-test log) introduced in ATA-6.

smartctl -a ... prints misleading messages then:

Error SMART Error Log Read failed: Input/output error
Smartctl: SMART Error Log Read Failed
Error SMART Error Self-Test Log Read failed: Input/output error
Smartctl: SMART Self Test Log Read Failed

Misleading kernel messages may appear during smartd startup:

... kernel: hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
... kernel: hda: drive_cmd: error=0x04 { DriveStatusError }
... kernel: ide: failed opcode was: 0xb0
... smartd[...]: Device: /dev/hda, Read SMART Self Test Log Failed
... smartd[...]: Device: /dev/hda, no SMART Self-Test log; remove -l selftest Directive from smartd.conf

(smartctl -x ... is not affected)

Smartctl and smartd should read the log directory (log address 0x00) to check whether the old logs are still supported and print an "unsupported" message if not.
