868.0. "Does VMS V7.1 inform of one bad power supply in an AS1000A and AS1000 ?" by PRSSOS::FONDI () Wed Apr 02 1997 03:41

	Hi 

 Questions:
 a)Could someone tell me if he has tested that, under VMS V7.1, on an AS1000A
   with dual redundant power, if a power dies, we have an entry in errlog.
 b)Same question for an AS1000

 I don't have these machines with VMS V7.1 to verify this.

 Actually i have one customer with AS1000A with fw from CD 3.8, VMS V6.2-1H3. 
 When one power dies there is no entry in errlog, and at the next power up self
 test the console tells you one power is bad and it shutdowns the other !

     ** PWR S 2 failed  **
     ** Interrupt mask disabled **
     ** Shutting power down **  


 From VMS engineering all is there in V7.1 to report this failure
 (below is the answer from VMS engineering note 405.1 in VAXAXP::VMSNOTES)


	Thank you
        Henri

   Please see the MIKASA notes I referenced over in VAXAXP::AlphaNotes
   69.1, where I first saw this question.  I expect you will have to code
   this yourself -- I thought that much was clear from the notes you likely
   already found.

	--

   If you want this sort of platform-specific diagnostic support added
   to OpenVMS, please contact the revelent platform engineering team with
   the request, and be prepared to make a case for making this change. 
   (OpenVMS does not normally handle these sorts of events without the
   input and the assistance of the processor engineering team...)

	--

   Based on a check of the V7.1 OpenVMS listings, the MCK$K_PS1FAIL and
   MCK$K_PS2FAIL signals, as well as MCK$K_TEMPWARN and various other
   signals, can be accepted by OpenVMS from the PALcode.  And OpenVMS
   does have code to call the make_errorlog routine present in module
   [CPU1B02]ERROR_ROUTINES_1B02.C, in routine exe$system_corrected_error,
   when the mck$l_pal_errcode value received from the PALcode indicates
   this is required.

   If it's not clear from the above, this support is entirely based on
   information received from the PALcode, and the Mikasa team is
   responsible for the PALcode...  (If you are running OpenVMS Alpha
   V7.1 and are not seeing these messages on power supply failure, then
   you'll want to check with the Mikasa engineering team to start to
   figure out why...)

	--

   (And if you're asking these questions, I'd acquire a copy of the source
   listings for OpenVMS -- ordering information is present in note 8.*
   or 9.* in VAXAXP::VMSNOTES.  The internal price of the source listing
   CD-ROM is cheap, and is well worth the subscription charge.)

Subj:	RE: How VMS informs of one bad power supply in an AS1000A

	Hello, Henri.

	Starting with V7.2, VMS will make an entry in the error log and
	print a message at the console for the following environmental
	fault conditions in Noritake and Noritake derivatives.

	Fan Failures
	Power Supply Failures
	Overtemperature Faults

	I have attached a code snippet below to give you an idea of the
	error messages sent to the console for each of these conditions.

	Regards,
		Tony




note: PinTake stands for AS1000A variations (Pinnacle/Noritake)

and to be complete on this subject
With AS1000A firmware from CD 3.9, no more ** Shutting power down **,
system stays alive with only one power after next power up.
