I tried building this src on 5L and got the same results. EFAULT error 14 (Bad Address) I built and tested on the same 5L system. Is STIOCMD supported on 5L????? As I mentioned below this src works fine on 4.3.

((fd = openx(argv[1], O_RDWR | O_NDELAY, NULL, SC_DIAGNOSTIC)) < 0)

struct sc_iocmd scmd;

(void) memset((char *)&scmd, 0, sizeof(scmd));

scmd.scsi_cdb[0] = 0x12;
scmd.scsi_cdb[1] = 0x0;
scmd.scsi_cdb[2] = 0x0;
scmd.scsi_cdb[3] = 0x0;
scmd.scsi_cdb[4] = 0x38;
scmd.scsi_cdb[5] = 0x0;

scmd.command_length = 0x06;
scmd.buffer = inq_data;
scmd.data_length = sizeof (inq_data);
scmd.flags = B_READ;
scmd.timeout_value = 60

if ( ioctl(fd, STIOCMD, &scmd) < 0 ) {
printf( "ioctl error on inquiry\n");
printf( "Errno: %d\n", errno);

It is not at all clear what you are trying to do or why.
AIX 4.3 is very very old and which AIX 5 are you using?

What is the device you are opening with openx() and do you know the device itself supports this operation or not.

STIOCMD is defined in /usr/include/sys/tape.h
Assuming you are doing some tape Diagnostics !!

Your code does not define inq_data
EFAULT sounds like this address is bad.

I am trying to send a Inquiry to a tape drive. This is just a snippet of the src. I need to port our (Sony) Tape diagnostics to AIX. The 5L build and test was done 5.1.

A Sony AIT tape drive. I am not getting error when opening the device.

The STIOCMD documentation doesn't show anything different for 5L vs. 4.3. I am not clear why my src works on 4.3 and not 5L.

The error occurs when the STIOCMD ioctl is sent.

After further testing this only happens when attached via FC. I have no problem with direct attached SCSI. Is there problems with the STIOCMD ioctl with FC?

On my test system (AIX 5.2) I am using a Emulex L9002L FC HBA with Brocade Silkworm switch and Sony SDZ-130 FC tape drive. I am getting errno 22 (invalid argument) I also had a customer try on 5.1 with a IBM 2 Gigabit Fibre Channel PCI-X Adapter Type 5740 and Cisco switch(errno 14 bad address) and Spectralogic FQIP FC bridge. According to all documentation I can locate online the STIOCMD should work on FC.

Also how can I a find the version of generic AIX tape driver? Is there a difference between it and the Atape driver? Can the Atape driver be used with non IBM tape drives?
