Note: The main difference between tape drive support in Irix
5.x and 6.x is the introduction for Data Compression
switching via software in Irix version 6.2. When
running Irix 5.x, the drive will always operate in the
compression setting determined by switch 6 on the
bottom of the drive (off=compression enabled
(default), on=compression disabled).
Irix V5.x
To configure Irix 5.x to use the Scorpion 40, you must modify
the file /var/sysgen/master.d/scsi as described below:
1.
Edit the file /var/sysgen/master.d/scsi and add the
following entry:
{DATTAPE,TPDAT,7,12,"SEAGATE","DAT 05573"/*DAT*/,0,0,{0,0,0,0},
MTCAN_BSF|MTCAN_BSR|MTCAN_APPEND|MTCAN_SETMK|MTCAN_PART|MTCAN_PREV|
MTCAN_SYNC|MTCAN_SPEOD|MTCAN_CHKRDY|MTCAN_VAR|MTCAN_SETSZ|
MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY,
/* minimum delay on i/o is 12 minutes, to allow the Drives
* full error recovery sequence to be performed. */
40, 12*60, 12*60, 12*60, 512, 512*512 },
Note: The string above contains four spaces between the
word
DAT
and the value
05573
.
2.
Rebuild the kernel using the autoconfig command (see
the autoconfig man page for details ). After the kernel is
rebuilt you will need to reboot the system again to bring
the changes into effect.
