We can make a deal: you make the change und I will check it out in our test environment.
May be the evaluation of the value can be protected by a flag set via the parameters key in the registry.
In
http://src.opensolaris.org/source/xref/nwam/nwam1/usr/src/uts/common/io/comstar/port/srpt/srp.h
I find
...
38 /*
39 * The following defines and structures are based on revision 16A of
40 * the T10 Project 1415-D SRP Protocol specification.
41 */
42
43 /* Protocol revsion information */
44 enum {
45 SRP_PROTOCOL = 0x0108,
46 SRP_PROTOCOL_VERSION = 0x0001,
47 SRP_REV_16A_IO_CLASS = 0x0100,
48 SRP_REV_10_IO_CLASS = 0xFF00, /* Old targets */
49 SRP_IO_SUBCLASS = 0x690E
50 };
51
...
On page 69 the value for "I/O Subclass" must read 609Eh and not 690Eh.
Of course the error should be corrected on OpenSolaris.
Maybe this will be done but in the current state of OpenSolaris/Solaris 11 this change will not be available for until end of year if at all.
If not changed in the initiator code users of the published binaries of OpenSolaris can't use srp targets in windows.
Thanks
Andreas

Betreff: RE: SRP target from OpenSolaris not recognized
>From the log file, this the error:
00000149 6.61263466 __srp_validate_ioc() !ERROR!:
00000150 6.61264229 Not an SRP CLASS(0x100)/SUBCLASS(0x690e).
00000151 6.61266088 srp_hba_create() !ERROR!:
00000152 6.61266470 Session Connection Failure.
00000153 6.61267614 srp_find_adapter() !ERROR!:
00000154 6.61267853 srp_hba_create returned 43
According to the log files, this is the lines that cause the problem:
if ( ( p_ioc_rec->info.profile.io_class != SRP_IO_CLASS &&
p_ioc_rec->info.profile.io_class != SRP_IO_CLASS_R10 ) ||
p_ioc_rec->info.profile.io_subclass != SRP_IO_SUBCLASS )
{
SRP_PRINT_EXIT( TRACE_LEVEL_ERROR, SRP_DBG_ERROR,
("Not an SRP CLASS(0x%x)/SUBCLASS(0x%x).\n",
cl_ntoh16( p_ioc_rec->info.profile.io_class ),
cl_ntoh16( p_ioc_rec->info.profile.io_subclass )) );
return FALSE;
}
The constants that are being used are:
#define SRP_IO_CLASS CL_HTON16(0x0100) /* T10 changed */
#define SRP_IO_CLASS_R10 CL_HTON16(0xff00) /* FF + high 8 bits of NCITS OUI */
#define SRP_IO_SUBCLASS CL_HTON16(0x609e) /* Low 16 bits of NCITS OUI */
So the problem is the io_subclass that 0x609e != 690e
Does anybody knows what the different subclass mean? I can easily change the code to allow this subclass as well, but I don't know what will happen next.
Thanks
