Re: [SLE] smartmon and opcodes..

I have a machine here that prints "kernel: ide: failed opcode was:

my SCSi disks, and I can't find any real reference to it either..

The IDE opcodes/commands can be found in the ATA specs - I don't have a
URL handy. You wouldn't see this for any SCSI drive, as they wouldn't
be using the IDE interface - but as the smartmontools were originally
only for IDE drives, perhaps it is some left over.

According to some code I saw at smrtmontools.sf.net, the 0xB0 command is
for "SMART ENABLE/DISABLE ATTRIBUTE AUTOSAVE ":

[Note: the second of these commands is listed as "Obsolete" in the ATA
specifications. It was originally defined in SFF-8035i. Most vendors
(IBM/Hitachi, Maxtor, Samsung, WD, among others) still implement it for
backwards compatibility.]

Maybe you can get rid of it by only running smartd on your SCSI drives.
