Re: System save / Tape performance issue



fixed

Paul:

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,

Mark S. Waterbury

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 hr.
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
