Hi all,
I am experiencing some difficulty using the generic device
driver (sg) for Linux SCSI.
I am running kernel 2.2.12 and sg3_30013.
The device with which I am trying to communicate is a SCSI-1
device, characterized as a Direct-Access device with a 1-byte
block size. The device is actually a modem.
The sg3_utilities/sg_readcap utility returns:
Read Capacity results:
Last block address = 10412 (0x28ac), Number of blocks = 10413
Block size = 1 bytes
The device has three LUNs (0, 1, and 2). 0 may be used for reads
and writes, but it is preferred to use LUN 1 for reads, and
LUN 2 for writes.
All reads and writes are to/from a region starting at Logical Block
Address 0. The device supports bus disconnect.
I am using an Adaptec 2930 Host Adapter.
I am using the write-followed-by-read method, instead of the
SG_IO ioctl, method.
The device file is opened read-write, non-blocking.
The timeouts specified in the sg_io_hdr_t structures for both
read and write are 5000 milliseconds;
The goal is to be able to monitor the device continuously for,
and read incoming data, and to be able to write (send) data
as required.
The problem I am having is evidenced in the attached syslog file
which covers the time from the most recent reboot until the
problem occurs.
The dump of the /proc/scsi files is also attached.
It seems that there is contention for the SCSI bus, and that when
a write is attempted while a read is being attempted (and possibly
times out), the write cannot proceed. This would not be so bad
in, and of itself, but when the command times out, the computer
is non-responsive (evidenced, e.g., by an ongoing ping from
another computer) for about two seconds.
This, is of course unacceptable.
It appears that if I could somehow avoid attempting to read unless
there is data (i.e., thereby avoiding the read timeout) things would
be OK. To this end, I attempted to use the SG_GET_NUM_WAITING
ioctl, but it appears that this does not return correct data unless
the read command has been written to the device -- but, of course,
by then it's too late to avoid the timeout if there is no data available to
be read. I have considered using the poll() system call, instead,
but a look at the sg code seems to indicate that this would be equivalent
to the use of the ioctl.
The transferred data is correct in all respects, both ways.
Some of the data in the syslog and the /proc files is mystifying,
as well. For example, despite the fact that I am writing to LUN 2,
and reading from LUN 1, these files show only LUN 0. Note
that the syslog plainly shows the LUNs 1 and 2 to be in the
read(10) and write(10) commands.
I have considered several possibilities to explain this behavior, viz.:
1. The SG driver does not work correctly with SCSI-1 devices.
For example, the format of the INQUIRY data is different, and
both the sg3_utilities and the Adaptec 2930 SCSI_Select
utility in the Host Adapter EPROM display it as though it
were SCSI-2 data, (despite the fact that ANSI version 1 is
returned in the data).
2. There is something wrong with the Host Adapter
3. I have misunderstood the operation of the SG_GET_NUM_WAITING
ioctl, or some other aspect of the sg driver.
4. I need to specify some options to the driver.
Any other suggestions are welcome.
Thanking anyone in advance who can shed some light on the solution
to this problem.
