Release Notes:

Version: 2.22
Date:	 03/13/98

The HP NetRAID NT monitor service tracks the status changes of the 
NetRAID adapter(s) and all the logical drives and physical drives. It
also performs consistency checks for all optimal redundant logical
drives as scheduled. All status changes are logged in the NT Event 
Viewer Application Log.

1. To control the service:
   There are two ways to control the NetRAID service. One is through
   Control Panel Services and the other is through a DOS utility.
   To pause, resume, stop or delete the NetRAID service use the 
   command line arguments: megactrl [-start], [-stop], [-pause], 
   [-resume], or [-del].
   
   To display the options, use: megactrl ?.  

2. To specify the consistency check schedule:

   At the DOS shell of NT, type:

   megactrl -cons -w# -d# -h# -datemm/dd/yyyy

	-cons:  Consistency check 

	-w#:	Weekly, valid options are: 0 = daily, 1 = every week
                2 = biweekly, 4 = every month, 12 = every 3 months,
                and 24 = every six months. When the -w0 option is 
                specified, then the -d# is ignored. The consistency
                check will start daily at the hour specified in the 
                -h# option.

	-d#:	Day of the week, Sunday=0, Monday=1, ... Saturday=6.

	-h#:	Hour in 24-hour format, 0=12:00AM, 23=11:00PM

	-date:	Start date in mm/dd/yyyy format. The consistency 
		schedule will start from this date on. Valid years are
	        1900 to 2038. If -date is not specified, the 
	        current system date is used.

        -enChkCon:
                Do consistency check at the next scheduled time 
                (default).

        -disChkCon:
                Do not consistency check at the next scheduled time.
    
   Example #1: megactrl -cons -w2 -d0 -h1 -date05/01/1998

   The consistency check will start on every other Sunday at 1:00 AM
   starting after 05/01/1998.

   Example #2: megactrl -cons -w4 -d6 -h0 -date04/01/2001

   The consistency check will start on Saturday every month at 
   midnight starting from 04/01/2001. 

   Example #3: megactrl -cons -w0 -d3 -h1 

   The consistency check will start every day at 1:00 AM. 

   The default is set for every Sunday at midnight starting from the
   current time. The schedule can be changed at any time by using the 
   megactrl -cons.

3. To stop or disable the consistency check:

   Use: megactrl -cons -abort. 

   This will stop all the consistency checks in progress.

   When NT 4.0 is shutdown, all the outstanding consistency check 
   process(es) will be stopped completely before NT indicates that it
   is safe to power off.

   When the NetRAID service is stopped, either by megactrl -stop or by
   the Control Panel service utility, all consistency checking in 
   progress is stopped.

   Use: megactrl -disChkCon to disable the consistency check.
   
   Use: megactrl -enChkCon to enable the consistency check.

   The default is set to enable the consistency check.
   
   
Known Limitations:

1. While a consistency check started by a NetRAID service scheduling 
   function is in progress, starting a second consistency check via
   the NetRAID Assistant utility will generate a warning message
   "Consistency Check cannot proceed." 

2. If consistency check is re-scheduled immediately after it is 
   started then it may be logged as "initial schedule"
	
3. If consistency check is aborted either thru "megactrl -cons -abort"
   or "megactrl -stop" option then it aborts consistency check running
   on all drives on all adapters even though the consistency check 
   processes were not started by the service program.

Changes from Version 2.21:

1. Fix for year 2000 support is implemented. Years supported are from
   1900 to 2038.

2. Infrequent high CPU utilization is eliminated.
