1. Make sure that a real tape drive is attached to your
virtual machine. If not, reissue the rewind after the
tape drive has been made available to your virtual
machine.
2. If a real tape drive is present, contact your system
operator to ensure that the real tape drive is in a
ready state. Then, reissue the command.
HCP902W System recovery failure; fatal I/O error
Explanation: During system initialization, an
unrecoverable input/output error occurred on the volume
containing checkpoint data.
On a second-level system, this could occur if the
checkpoint or warm start volume is a minidisk, and you
have defined the SYSCKP or SYSWRM area on
cylinders or pages that do not exist on the minidisk.
System Action: The system enters a disabled wait
state (wait state code = 902).
Operator Response: Re-IPL the system. If the error
recurs, move the failing volume, if possible, to another
drive and retry the IPL.
The volume containing the checkpoint data is defined
on the SYSCKP parameter of the SYSRES macro in
HCPSYS.
The volume containing the warmstart data is defined on
the SYSWRM parameter of the SYSRES macro.
If this is a second-level system, enter QUERY VIRTUAL
vdev for the checkpoint and warm start devices. Verify
that the SYSWRM and SYSCKP cylinders or pages
exist on the device, and change them if necessary.
If the problem persists, take a stand-alone dump and
contact your IBM Support Center personnel for
assistance.
HCP904E System recovery failure; incorrect
warm start data
Explanation: During a system warm start procedure,
the warm start module encountered incorrect or missing
data. This error will also occur for one of these reasons:
v A new nucleus was IPLed with the specification of a
warm start.
v There was an error in the checkpoint data saved. You
may need to format the volume containing the
checkpoint cylinders.
System Action: Message HCP9205A is displayed
asking the operator whether a force start is desired.
Operator Response: The operator should enter
FORCE if a force start is desired. Otherwise, the
operator should enter STOP to stop processing.
HCP902W HCP909W
HCP904W System recovery failed; incorrect warm
start data
Explanation: During a system warm start procedure,
the warm start module encountered incorrect or missing
data. This error occurs if you IPLed a new nucleus and
specified a warm start. It also occurs if there was an
error in the checkpoint data saved.
You may need to format the volume containing the
checkpoint cylinders.
System Action: The system enters a disabled wait
state (wait state code = 904).
Operator Response: This message indicates the
checkpoint information needed for warm start
processing is incorrect or missing. IPL the system and
specify a FORCE start. If CP cannot perform a FORCE
start, IPL the system and specify a COLD start. If the
problem persists, do the following:
v Take a stand-alone dump of the system.
v Using the DDR utility with the PRINT option, print the
contents of the checkpoint cylinders.
Save this output and give it to the IBM Support Center
personnel to analyze.
After IPLing the system, use ICKDSF or the CPFMTXA
command to check the format of the volume containing
the checkpoint cylinders. Refer to z/VM: System
Operation for additional information.
HCP908I SYSTEM FAILURE ON CPU nnnn,
CODE - code
Explanation: The system has encountered a severe
software failure that caused a system dump. CPU nnnn
indicates the failing processor. code is a CP abend
code.
System Action: A system abend dump to the dump
device immediately follows this message, and then
automatic or normal restart procedures are initiated.
Operator Response: Save the CPU number printed at
the console, including the documentation of activity prior
to the problems with system operation, and contact your
IBM Support Center personnel for software support.
HCP909W SYSTEM DUMP DEVICE NOT READY
Explanation: It is not possible to write on the system
dump device because it is not in a ready state.
System Action: The system enters a wait state (wait
state code = 909).
Operator Response: Make the system dump device
ready; the dump operation continues.
