Subject: SATA passthrough fails to differentiate between SCSI devices
Date: Mon, 16 Jan 2006 07:19:36 +0000 [thread overview]
Message-ID: <43CB4908.90502@mit.edu> (raw)
[-- Attachment #1: Type: text/plain, Size: 12458 bytes --]
So, if I do `for dev in /dev/sd?; do smartctl -d ata -i $dev; done`, I get identical output for all 8 SCSI disk devices available (excluding timestamps). Additionally, if I do `for dev in /dev/sd?1; ...`, I get the identical output for all of the devices with a filesystem probed, but this set of output is for a _different drive_ than the /dev/sd? output. Output is listed below, after some info about my drives. lspci and dmesg excerpts follow.
All SCSI disk access (including usb-storage) seems to work properly. Fetching smart data from my ATA drives seems to work fine as well (that is, hda works, and hdc and hdd are reported as not having any SMART data, which is correct also). As far as I can tell, this problem only arises when the libata passthrough is used.
My disk setup is as follows:
onboard VIA VT82C[56]86 PATA controller
hda: WD Caviar (WD1200JB-00EVA0)
PCI Promise TX4 SATA controller
sda: Maxtor MaXLine Plus III (7L250S0)
sdb: Seagate Barracuda 7200.8 (ST3250823AS)
onboard VIA VT6420 SATA RAID controller (used in non-RAID mode)
sdc: Samsung SP1614C
sdd: Samsung SP1614C
usb-ehci
sd[efgh]: 4-slot USB cardreader; 1GB CF card was in during bootup
unused and disabled onboard Promise SX4 SATA RAID controller
sysfs has the correct information:
