I'd like to know if anyone else with a Promise SATA300 TX2/TX4 using
sata_promise is seeing problems with sending ATA cmds to
enable/disable smart auto-offline mode and/or attribute auto-saving.
(smartctl -o on -S on ...)
According to smartctl, my drives support both of these features, but
when the corresponding smart cmds are sent via the driver, the card
returns an error indicating illegal commands:
smartctl -a -d ata /dev/sda
...
Offline data collection
capabilities: (0x5b) SMART execute Offline immediate.
Auto Offline data collection
on/off support.
...
SMART capabilities: (0x0003) Saves SMART data before entering
power-saving mode.
Supports SMART auto save timer.
...
When smartd actually sends these ata cmds to the driver (with my
patched kernel to output smart error codes):
auto-offline cmd (which is obsolete in atapi-7)
ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
ata4.00: tag 0 cmd 0xb0 Emask 0x2 stat 0x50 err 0x0 (HSM violation)
ata4.00: smart cmd 0xdb (obsolete or reserved feature)
auto-save cmd
ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
ata4.00: tag 0 cmd 0xb0 Emask 0x2 stat 0x50 err 0x0 (HSM violation)
ata4.00: smart cmd 0xd2 (enable/disable attribute autosave)
Are these cards failing to pass through these specific cmds? These two
are the only ones which seem to show up in dmesg while using
smartctl/smartd.
Thanks -Andrew
