HCP448E HCP454I
HCP448E System name not quiesced{.
Outstanding I/O on device rdev.| due to
an outstanding external interrupt.}
Explanation: You did not quiesce the indicated system
in order to allow the save to continue.
System Action: CP halts processing of the SAVESEG
or SAVESYS command and does not save the NSS or
saved segment skeleton file.
Programmer Response: Ensure that the NSS or
saved segment does not have any outstanding I/O or
external interrupts. Then issue the command again.
HCP449E Your userid is not authorized to IPL
system name.
Explanation: You issued an IPL specifying restricted
NSS name without the necessary authorization in the
CP directory. If an external security manager (ESM) is
installed on your system, you may receive this message
if you are not authorized to IPL the specified system.
System Action: The command is not executed;
system operation continues.
Programmer Response: Obtain the authorization to
access the restricted NSS from your system
administrator.
HCP450W CP entered; disabled wait PSW psw
Explanation: The virtual machine loaded a disabled
wait PSW, identified by psw.
System Action: System operation continues. The
virtual machine enters console function mode. If the
virtual machine was running disconnected, it is logged
off the system.
User Response: This message may have been
preceded by an explanatory message from the
operating system running in your virtual machine. If it is
not, examine the PSW portion of the message. To
interpret the wait state code in the PSW, refer to the
section on wait states of the corresponding manual for
the system you were running in your virtual machine.
Take the specified corrective action, then re-IPL the
virtual system again.
The following paragraph is an explanation of a possible
wait state situation for the CMS environment. It is not
the only wait state that can be sent to a user. It is just
an example of what the wait state might look like.
If you were running CMS, and you received this
message with the PSW ‘00060000 00000070’, then
CMS received a virtual machine check. Re-IPL CMS
and try again.
Programmer Response: Examine the PSW portion of
the message. Ensure that the program running in the
virtual machine has a valid load PSW (LPSW). If not,

determine why the PSW loaded was not masked for
interrupts.
HCP452I CP entered; external interrupt loop
Explanation: While handling an external interrupt, the
user’s virtual machine external new PSW is enabled for
an external interrupt condition that will not be cleared
upon acceptance (for example, the timer is not expected
to contain a negative value). It is possible to receive an
interrupt condition from the CPU timer and the
time-of-day (TOD) clock comparator that produces this
loop.
System Action: System operation continues. The
virtual machine enters CP command mode.
User Response: To continue, IPL the virtual system
again.
Programmer Response: Determine why the external
interrupt new PSW is enabled for an interrupt condition
that will not be cleared upon acceptance (that is, the
timer is not expected to contain a negative value).
HCP453W CP entered; program interrupt loop
Explanation: A program interrupt occurred at the
address specified in the virtual program new PSW.
System Action: System operation continues. If no
virtual CPU remains operational, the program interrupt
is reflected to the virtual machine, the virtual CPU is
placed in hard stop, and the user enters console
function mode. If the virtual machine was running
disconnected, it is logged off the system.
User Response: After correcting the error, reissue the
IPL command.
Programmer Response: To determine the reason for
the loop, examine the program-check information in
page zero of your virtual storage. If this error occurred
immediately after the IPL command, the problem may
be that you are trying to run a 370 guest in XA mode.
z/VM no longer supports 370 mode; try using the 370
Accommodation Facility.
HCP454I Line rdev disabled
Explanation: The communication line is disabled as a
result of I/O errors. See message HCP455I for reason
of error.
System Action: None.
Operator Response: Check the line for any possible
problems, and then try to enable the line.
