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.
