30 ZSCP-EVT-CPU-SWITCH
Cause. The SCP process issues this noncritical event message when there is a problem
with tracing (initiated with a TRACE command). The error code indicates the cause.
Effect. The SCP process issues this event message, turns tracing off, and continues
processing.
Recovery. Determine a recovery action based on the SPI error code.
30 ZSCP-EVT-CPU-SWITCH
The SCP process issues this noncritical event message when something causes its
backup process to take over and become the primary process.
ZCOM-TKN-OLD-CPU
specifies the CPU number, from 0 through 15, for the old primary CPU.
ZCOM-TKN-NEW-CPU
specifies the CPU number, from 0 through 15, for the new primary CPU.
ZCOM-TKN-CPU-SWITCH-CAUSE
specifies the reason for the switch. The possible values are:
Cause. The SCP process issues this noncritical event message when its backup process
takes over from the primary process.
Effect. The new primary SCP process starts a backup process and continues message
processing.
Recovery. Informational message only; no corrective action is needed.
Tokens in Event Message

Message Text
CPU changed from (<1>) to (<2>) because <3>
ZSCP-VAL-HW-FAILURE A primary CPU hardware failure occurred.
ZSCP-VAL-INTL-ERROR A primary CPU software failure occurred.
ZSCP-VAL-MEM-OFF-BALANCE A memory problem occurred, and memory was
not properly deallocated in the primary CPU.
ZSCP-VAL-PRIM-STOP The primary SCP process was stopped, and the
backup SCP process has taken over.
ZSCP-VAL-SWITCH-REQ The switch was requested, probably by an
operator.
