Have you ever seen something like this "*06.11.30 SRPMVS *CNZ0010A VARY COMMAND DELAYED DUE TO RESOURCE
* CONTENTION ON SYSIEFSD.Q4 " ?
Today I was trying to vary a volume offline and the system throwed me this error.. I couldn't find any contention for the volume that I tried to bring online. But however the volume went offline in sometime.
what is this resource SYSIEFSD.Q4 ? why is it being needed to bring a volume offline?
I suppose when you vary a device online that various system control blocks are updated. And because of mulitasking and multiple CPU's the system makes sure that the control blocks are updated in an orderly manner.
