Logical Partition Hangs or Loops (No SRC)
This procedure is for the case where the hanging or looping partition does not
display an SRC in the Primary partition’s
Work with Partition Status screen.
You are here because:
v
Logical partition operation is hung (very low processor activity indicated on the
control panel with workstation(s) input inhibited).
v
Logical partition operation is in a loop (very high processor activity indicated on
the control panel with workstation(s) input inhibited).
A logical partition hang or loop is the result of either:
v
A software failure.
v
Software improperly handling a hardware failure.
This procedure assumes that the logical partition completed an IPL and that at
least one user had successfully signed on before the condition occurred.
The purpose of this procedure is to:
1. Help you report the problem with enough error data to permit an APAR
investigation to resolve the software problem.
2.
Provide you with direction to identify any possible hardware failure.
Perform the following:
1. Is the logical partition operational from any workstation?
No Yes

Work with the system operator to complete the appropriate problem
handling procedures. See:
