FastTrak66/100 v1.02.0.19 Ioctl Interface [03.19.2001] [SYNOPSIS] #include <sys/ioctl.h> int ioctl(int d, int command, *args) The "first" argument d must be an open file descriptor , such as "/dev/sda" , "/dev/sdb" , ... ( which FastTrak driver mapped ) [IOCTL COMMANDS LIST] (1) [ARGUMENT] command: 0x3801 args : ft_info_t *args [DESCRIPTION] get all Adapters/Arrays status (2) [ARGUMENT] command: 0x3802 args : unsigned char args[512] [DESCRIPTION] Identify Drive x args[0] = '1' -> identify Primary/Master drive args[0] = '3' -> identify Secondary/Master drive (3) [ARGUMENT] command: 0x3803 args : ft_swapbox_t *args[FT_Max_Dev] [DESCRIPTION] get all Swap Boxes information (4) [ARGUMENT] command: 0x3804 args : unsigned char args[512] [DESCRIPTION] set Disable Mirroring Synchronous flag : FastTrak driver allows user to disable starting mirroring , when system is critical and be going to rebuild array , untill the flag has been disabled. args[0] = '1' -> disable mirroring synchronous args[0] = '0' -> enable mirroring synchronous (5) [ARGUMENT] command: 0x3806 args : snmp_log_t args[50]; [DESCRIPTION] dump event log such as Disk Offline , Disk Plugged in , Disk Rebuild Started , Disk Rebuild Completed , ....... [RETURN VALUE] On success, zero is returned. On error, -1 is returned. If argument "args" is NULL pointer , 0x10 will be returned.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
