SCSI descriptor sense changes, testing needed
Kenneth D. Merry

Thu Sep 22 20:08:06 UTC 2011
I have attached a set of patches against head that implement SCSI
descriptor sense support for CAM.
Descriptor sense is a new sense (SCSI error) format introduced in the SPC-3
spec in 2006. FreeBSD doesn't currently support it.
Seagate's new 3TB SAS drives come with descriptor sense enabled by default,
and it's possible that other newer drives do as well. Because all the
sense key, additional sense code, and additional sense code qualifier
fields are in different places, the CAM error recovery code will not do the
right thing when it gets descriptor sense.
These patches do bump up the size of struct scsi_sense_data, and so I have
incremented CAM_VERSION as well. I have discussed this with re@, and it
looks like we'll be putting the changes in before 9.0, so it ships with
support for newer SCSI devices.
A number of things have changed in these patches, but in particular, it
would be good to test the following:
- The sa(4) (SCSI tape) driver. The residual handling code, which looks
at the sense data, has changed.
- The Playstation 3 CDROM driver.
- Firewire target mode.
- umass devices with the NO_INQUIRY_EVPD quirk.
Also, please let me know if you see any anomalies with the sense printing
code. In the common cases the output should look identical to the old
code, but in some cases it will be a little different. e.g.:
# camcontrol inquiry da40 -v
pass47: <SEAGATE ST33000650SS 0002> Fixed Direct Access SCSI-6 device
pass47: Serial Number 9XK0GAJ70000S125XDNU
pass47: 300.000MB/s transfers, Command Queueing Enabled
(Seagate 3TB drive)
# camcontrol modepage da40 -m 10 |grep D_SENSE
D_SENSE: 1
(Descriptor sense is enabled)
# camcontrol modepage da40 -m 15 -v
(pass47:mps1:0:47:0): MODE SENSE(6). CDB: 1a 0 4f 0 ff 0
(pass47:mps1:0:47:0): CAM status: SCSI Status Error
(pass47:mps1:0:47:0): SCSI status: Check Condition
(pass47:mps1:0:47:0): SCSI sense: ILLEGAL REQUEST asc:24,0 (Invalid field in CDB)
(pass47:mps1:0:47:0): Field Replaceable Unit: 1
(pass47:mps1:0:47:0): Command byte 2 bit 5 is invalid
(pass47:mps1:0:47:0): Descriptor 0x80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00
camcontrol: error sending mode sense command
(The FRU and Sense Key Specific entries are on separate lines, and a
vendor-specific sense descriptor is printed out in hex format.)
Anyway, I'd appreciate any testing and feedback on these changes. As I
said, they will probably be in 9.0, so if there are any issues it would be
better to find them now. :)
Thanks,
Ken
