SUN MANAGERS -- THANKS A BUNCH !!!!!! --- WONDERFUL FORUM FOR SOLUTIONS

What follows is a summary of the information that I requested the first part of this week regarding attachment of an HP DAT 'compatible' tape drive to a SUN IPC running 4.1.3.

The solution involved the modification of two files, stdef.h and st_conf.c, rebuilding the kernal, and setting the correct scsi unit number, 4 for my configuration.

Details follow:

/usr/kvm/sys/scsi/targets/stdef.h:
...
#define ST_TYPE_EXABYTE 0x28 /* Exabyte */
/* #define ST_TYPE_EXB8500 0x29 /* Exabyte */
#define ST_TYPE_HPDAT 0x29 /* HP DAT */
...

/usr/kvm/sys/scsi/targets/st_conf.c:
...
},
/* Exabyte 8mm 5GB cartridge */
/*
{
        "Exabyte EXB-8500 8mm Helical Scan", 16, "EXABYTE EXB-8500",
        ST_TYPE_EXB8500, 1024,
        (ST_VARIABLE | ST_BSF | ST_BSR | ST_LONG_ERASE),
        5000, 5000,
        { 0x14, 0x00, 0x8C, 0x8C },
        { 0, 0, 0, 0 }
},
*/
/* Exabyte 8mm 2GB cartridge */
{
        "Exabyte EXB-8200 8mm Helical Scan", 16, "EXABYTE EXB-8200",
        ST_TYPE_EXABYTE, 1024,
        (ST_VARIABLE | ST_BSF | ST_BSR | ST_LONG_ERASE | ST_AUTODEN_OVERRIDE),
        5000, 5000,
        { 0x00, 0x00, 0x00, 0x00 },
        { 0, 0, 0, 0 }
},

/* HP-354X0A 3.81mm DAT Helical scan */
{
        "HP-354X0A 3.81mm DAT", 2, "HP",
        ST_TYPE_HPDAT, 10240,
        (ST_VARIABLE | ST_BSF | ST_BSR | ST_LONG_ERASE | ST_AUTODEN_OVERRIDE),
        6000, 6000,
        { 0x00, 0x00, 0x00, 0x00 },
        { 0, 0, 0, 0 }
},
