Thank you everyone for all the tips.
I need to remember to account for the extra time if doing a system save after an IPL.

I enabled ASYNCBRING back in 2012 when on V6R1.
I wasn't sure if it remained enabled through an OS upgrade.

What do you mean by "an unattended system save" -- did you use GO BACKUP,
or GO SAVE option 21, or BRMS, or what?

Also, you did not mention what version / release of OS/400 or IBM i
(i5/OS) this is happening on?

If you are on V6R1 or above, take a look at this document:

This new feature is intended to help speed up the time to save IFS objects

Do a google search for "ASYNCBRING(*YES)" (without quotes) and you will
find a number of good articles, etc.

Hope that helps,

I did an unattended system save on our Pencor06 R&D partition Monday
evening, the save ended abnormally because it didn’t complete within the
360 minutes.
I will be increasing the system max restricted time from 360 to 420,
just in case this occurs again.
System was at 39% of 12,565 or 4900.
System was in restricted state.
Save was using 2 of 4 LTO5 drives. Normally my overall rate is 900 gb
I expected the save to be done in about 5 hours.
Actual was 6+ hours, if it would have finished.
It was saving the IFS when it ended because of the time limit.
Any thoughts of where to look for issues.

Thank You
