If I switch two disks around and do a scan, nothing changes. I need to delete the disks and then scan to have the change noted. Is this expected behavior? Does this mean I must delete a disk with a command when it it removed? This is problematic in that I do not know which disk may have been removed! The old /proc/scsi interface would allow you to update the idea of which things are attached without knowing which they were and (key point) without messing up a device that is unchanged and mounted. Is this possible with libata? I know you want logs. But I really feel that if the intended use is unclear, I can waste lots of time here sending in logs when trying to do things that the driver does not intend I do. Step 1 must surely be to tell the driver's expectations/limits first. If I remove or insert a disk, there is nothing at all added to the kernel log. There only seems to be activity when I echo something to a file in /sys. If I remove disks (but run no commands on the computer) and then do a scan, I get this in the log: Aug 3 08:16:43 aies1 kernel: ata1.00: qc timeout (cmd 0xec) Aug 3 08:16:43 aies1 kernel: ata1.00: failed to IDENTIFY (I/O error, err_mask=0 x4) Aug 3 08:16:43 aies1 kernel: ata1.00: revalidation failed (errno=-5) Aug 3 08:16:43 aies1 kernel: ata1: failed to recover some devices, retrying in 5 secs Aug 3 08:16:45 aies1 kernel: ata2.00: qc timeout (cmd 0xec) Aug 3 08:16:45 aies1 kernel: ata2.00: failed to IDENTIFY (I/O error, err_mask=0 x4) Aug 3 08:16:45 aies1 kernel: ata2.00: revalidation failed (errno=-5) Aug 3 08:16:45 aies1 kernel: ata2: failed to recover some devices, retrying in 5 secs Aug 3 08:16:55 aies1 kernel: ata1: port is slow to respond, please be patient Aug 3 08:16:57 aies1 kernel: ata2: port is slow to respond, please be patient Aug 3 08:17:18 aies1 kernel: ata1: port failed to respond (30 secs) Aug 3 08:17:18 aies1 kernel: ata1: soft resetting port Aug 3 08:17:20 aies1 kernel: ata2: port failed to respond (30 secs) Aug 3 08:17:20 aies1 kernel: ata2: soft resetting port Aug 3 08:17:25 aies1 kernel: ata1: port is slow to respond, please be patient Aug 3 08:17:27 aies1 kernel: ata2: port is slow to respond, please be patient Aug 3 08:17:48 aies1 kernel: ata1: port failed to respond (30 secs) Aug 3 08:17:48 aies1 kernel: ATA: abnormal status 0xD0 on port 0x30EF Aug 3 08:17:48 aies1 kernel: ATA: abnormal status 0xD0 on port 0x30EF Aug 3 08:17:48 aies1 kernel: ATA: abnormal status 0xD0 on port 0x30EF Aug 3 08:17:48 aies1 kernel: ATA: abnormal status 0xD0 on port 0x30EF -- Roger Oberholtzer OPQ Systems AB Ramböll Sverige AB Kapellgränd 7 P.O.
