Since I got myself involved, I may as well try to see it out.
What you appear to need - as is mentioned in the redbook to which George
referred: http://www.redbooks.ibm.com/abstracts/sg242070.html - are the
*maintenance* manuals. In principle, these manuals are used only by the folk
responsible for *maintaining* your hardware but - the last time I was in a
machine room - you should be able to find the manual in those wire tracks
used as a bookcase for maintenance manuals.
Thus if you have an IBM 9037 Sysplex Timer, I would expect one of the
following manuals to be present in those wire racks. If they are not, I
believe you should be entitled to ask IBM that they are available there.
- Sysplex Timer 9037 Maintenance, SY27-2605 (9037-001)
- Maintenance Information for the 9037 Model 2 Sysplex Timer, SY27-2641
The section of the redbook which contained these references starts with the
following:
<quote>
Appendix B. 9037 Log - Reason Codes
All messages appearing in the event log or displayed at the 9037 console are
accompanied by a number referred to as the reason code (RC). The reason
codes are primarily used by the IBM Service Representative to determine
corrective actions to be taken.
</quote>
Appendix B then goes on to list all the reason codes with a little
description for each. This may be the same information that you will find in
those Y manuals and may be all you need.
Incidentally, I found those Y manuals very helpful when I used to work with
machines like the 3745 so there's actually something behind the word
"primarily" as used in that redbook text.

Subject: Re: Sysplex timer
Yeah, we are planning STP, but now we need to synchronize our clocks. I
know
we can't automatically update time if it's deviation is higher than 5
seconds, but I SUPPOSE you can connect to the ETS. Nevertheless, now we
are
doing manual synchronization. My problem is we couldn't find a manual
describing the different states and errors we can find on Sysplex Timer.
Shane proposed two of them; but I couldn't find the first one, and the
second one does not describe such errors.
By the way, we are synchronizing now, so the manuals are not urgent. I'm
only asking for those books, just in case we have any kind of problem in
the
future.
Thank you very much!

Being at home at present, I'm presuming this is the manual about the
size of a (large) novel.
Paper only, from IBM only IIRC.
There are *very* specific protocol requirements which I presume you know
about. NTP won't do the job, and from memory you need to be within 5
seconds of the time source, or the synch is dropped.
I'll have a look when I get into the office tomorrow.
Of course IBM are now encouraging us to consider (real) sysplex timers
as just outdated junk what with STP being the new kid in town.
Looking after the current users as always...
