I guess I'll run it by you guys because we're at our wits end. I'm also g=
etting ready to peruse the Veritas support page (you can see I'm desperat=
e).
Environment:
NBU 4.5 Master on Sun E450 (Solaris 2.8), L700 robotic library attached.
NBU 4.5 Media on Sun E450 (Solaris 2.8), L700e robotic library attached.
Patch level on both I believe is 2, but I can verify if you need it.
Problem:
A couple of months ago we upgraded from NBU 3.4 to NBU 4.5 which was very=
uneventful. Everything continued to function normally. Last week, we dec=
ided to switch from Frequency based scheduling to Calendar based scheduli=
ng (one of the main reasons we went to 4.5 in the first place). We are be=
ginning to regret the decision because nothing, scheduling wise, has work=
ed since. The way we look at calendar based scheduling is if we schedule =
a policy (or policies) to start at 2000 each night and give it a window u=
ntil 0700 the next morning, one would think those policies would start at=
2000. What we're seeing is some of them may start but many others do not=
=2E So we manually start them. All looks OK but sometime after midnight, =
a bunch of policies get queued up. Unfor
tunately, those policies were already running. So why the duplicates?
I tell you, I have used calendar based scheduling before in lesser produc=
ts and didn't have problems like these. Naturally the Veritas documentati=
on is less than stellar when it comes to this. In fact, we've yet to find=
anywhere in the documentation what the "Retries After Runday" flag is fo=
r. Even doing a search on the exact text in the electronic manual finds l=
ittle useful information. We used that flag on several policies and when =
they didn't behave like we planned, we de-selected that option.
I guess now to my question: Does anybody understand calendar based schedu=
ling as it applies to Veritas NBU and are you willing to share what you k=
now? In the interest of time, perhaps we should keep it to 20 pages! In m=
y mind it shouldn't be this complicated, however, if there were considera=
tions that needed to be made and planned for, it might have been a good i=
dea to outline that somewhere. I think as a user community we may have be=
en a little selfish and short-sighted asking for new and improved feature=
s in each version of NBU. Perhaps we should be clamoring for better docum=
entation to help us use what we have.
Epilog:
After much manual babysitting last night and this morning, including a lo=
t of cancellations of duplicate jobs, it looks as though everything finis=
hed last night (finally). Hopefully everything is in synch now ... but th=
at's what we thought yesterday and the day before.
Thanks for the opportunity to vent ... I get tired of running in circles =
after a while.

Dennis
