Hi,
It does appear I’m not successfull to get a serial number for disks in a
JBOD (Just a Bunch of Disks), which is connected throu FC adapter(ql2300).
I’m using spti and the code works for direct-attached disks. The funny
thing is that I’m not getting an error but the returned ‘unit serial number
page’/buffer is not properly filled up.
code: (as from DDK spti exmaple)
…
ZeroMemory(&sptwb,sizeof(SCSI_PASS_THROUGH_WITH_BUFFERS));
ZeroMemory(buffer,2048);
sptwb.spt.Length = sizeof(SCSI_PASS_THROUGH);
sptwb.spt.PathId = 0;
sptwb.spt.TargetId = 0;
sptwb.spt.Lun = 0;
sptwb.spt.CdbLength = CDB6GENERIC_LENGTH;
sptwb.spt.SenseInfoLength = 24;
sptwb.spt.DataIn = SCSI_IOCTL_DATA_IN;
sptwb.spt.DataTransferLength = 192;
sptwb.spt.TimeOutValue = 2;
sptwb.spt.DataBufferOffset =
offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS,ucDataBuf);
sptwb.spt.SenseInfoOffset =
offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS,ucSenseBuf);
sptwb.spt.Cdb[0] = SCSIOP_INQUIRY;
sptwb.spt.Cdb[1] = 0x01;
sptwb.spt.Cdb[2] = 0x80;
sptwb.spt.Cdb[4] = 192;
length = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS,ucDataBuf) +
sptwb.spt.DataTransferLength;
status = DeviceIoControl(fileHandle,
IOCTL_SCSI_PASS_THROUGH,
&sptwb,
sizeof(SCSI_PASS_THROUGH),
&sptwb,
length,
&returned,
FALSE);
PrintStatusResults(status,returned,&sptwb,length);
…
this code works OK (same machine) with a direct-attached (local) disk
(output as from DDK sample):
Read 74h bytes of inquiry data Information.

and the output for the JBOD disk (btw. IOCTL_SCSI_GET_INQUIRY_DATA works
fine)
Read 40h bytes of inquiry data Information.

fot those not familir with spti sample number:
unit serial page number starts in line beggining with ‘050’ :
byte 00: peripheral ‘qualifier && dev. type’
byte 01: page code ( 80h )
byte 02: reserved
byte 03: page length
byte 04-: serial number in ascii (should have only alphanumeric values
but it is not the case with JBOD disk
first four bytes are OK but the rest from 04- seems bad!( null char.?)
PS. the JBOD disk does have a serial number because I can see it with
JBOD’s vendor app.
any help would be appreciated,
Davor
