Yes, I have this code in scsi_id (scsi_serial.c), AFAIR the same as we
once had in the kernel. The return 1 means we won't use this id:
/*
* ASSOCIATION must be with the device (value 0)
*/
if ((page_83[1] & 0x30) != 0)
return 1;
The source code is included with the udev release (under the extras
directory), or at:
http://www-124.ibm.com/storageio/scsi_id/scsi_id-0.3.tar.gz
