shadow too old: (old date/ today: new date)
STAP TYP 00:00:00 NAME
shadow too old: (old date/ today: new
->MSGDEV (M.SHOF)
date)
A shadow's age is tested once per day. In this case the last shadow is too old (older
than one day), which can endanger the functional capabilities of the DC Server. This
can occur because the system has attempted to transfer bad disk blocks from the
shadow (even when shadow mode is switched off), in order to keep the system running
as long as possible with a bad disk situation.
For DC Servers having two disk units, switch on shadow operation
(in $S set parameter SHAD=EIN).
For DC Servers having only one disk, set cyclic shadow structuring ($SY,SHAD=ZEA).
