In the routine init_hr_disk(), look for the line
device_descr[HRDEV_DISK] = describe_disk;
and add another
device_status[HRDEV_DISK] = disk_status;
Then define the routine
int disk_status( int idx ) {
if ( /* disk 'idx' is running OK */ ) {
return 2; /* running */
}
if ( /* disk 'idx' is down */ ) {
return 5; /* down */
}
}
(for whichever status values you wish to return).
You can probably assume that all the information
set up in 'Save_HR_Disk_Specific' and 'Save_HR_Disk_General'
will be available and refer to the disk in question.
You can also do something similar for hrDeviceErrors
by registering
device_errors[HRDEV_DISK] = disk_errors;
and defining 'disk_errors' appropriately.
(It follows the same framework, but returns the number
of errors for that particular disk)
See 'host/hr_network' for an example.
