Hi,
I am running RH7.2 with a RAID mirror controlled by an onboard PDC20265/ FastTrack 100 Lite. I am using the drivers supplied by Promise. -How do I check whether a drive is failing directly from sw without a reboot? Promise has supplied a header file (included below) together with the driver but I can't figure out how to make it work, I am not that good in C programming.

FastTrak66/100 v1.2.0.9 Ioctl Interface [02.11.2001]
[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.
