z/VM: System Messages and Codes Š CP - z/VM - IBM

System Action: System operation continues.
Operator Response: Attempt to “clean-up” the
status-pending condition by physically powering off or
varying offline the malfunctioning control unit or isolating
the failing channel path. The VARY PATH command
may be used to isolate the channel path.
Programmer Response: Examine the MDR
(miscellaneous data record) within LOGREC for specific
hardware error conditions. If the problem persists,
contact your IBM Support Center personnel to diagnose
and correct the hardware problem.
HCP2263I Path yy to device rdev is available and
online.
Explanation: A path, to the device, that was
previously unavailable is now available. CP has brought
the path online for use.
System Action: The channel path is logically varied
online.
Operator Response: None.
HCP2264I Device rdev is available and online.
Explanation: A device that was previously unavailable
is now available. CP has brought the device online for
use.
System Action: The device is varied online.
Operator Response: Any pending actions to use the
device may now be performed, for example, attaching
the device to a VM guest.
HCP2266E SET RESERVED was not processed.
Total reserved would exceed the
current pageable DPA by nnnnnnnn
pages.
Explanation: CP maintains a count of the total
number of pages specified on all SET RESERVED
commands. When a SET RESERVED command is
issued and the command is increasing the reserved limit
for the user, the new total is compared against the
current pageable DPA (dynamic paging area). If the new
total exceeds the current pageable DPA, CP issues this
message and the user’s reserved pages value is not
changed.
If this command were to complete successfully, the total
reserved pages value would exceed the pageable DPA
by nnnnnnnn pages.
System Action: The reserved pages value for the
user is not changed. The system continues with the
settings that were in place prior to the command.
User Response: Compare the number of pages given
in the message (nnnnnnnn) with the amount you are
increasing the user’s reserved value. You can issue
QUERY RESERVED to identify the current reserved
HCP2263I HCP2270I
setting. If you are increasing the user’s reserved value
by more than the value given in the message, either
reissue the command with a smaller value or reduce the
reserved amount for other users before retrying the
command. Note that adjusting the value specified by the
value given in this message may still not work as the
amount of pageable DPA changes.
If you are increasing a user’s reserved value by less
than the value given in the message, then there were
already too many pages allowed to be reserved before
the command was issued. This can occur because the
current pageable DPA is constantly changing. It is now
smaller than it was when the previous SET RESERVED
command or commands were issued. Reduce the
reserved pages value for one or more other users
before retrying the command.
Note: In general it is not a good idea to have the total
reserved pages near or greater than the number
of frames in the pageable DPA.
HCP2267E SET RESERVED completed
successfully. Total reserved exceeds
the current pageable DPA by nnnnnnnn
pages.
Explanation: CP maintains a count of the total
number of pages specified on all SET RESERVED
commands. When you issue a SET RESERVED
command that decreases the reserved limit for the user,
the new total is compared against the current pageable
DPA (dynamic paging area). If the new total exceeds
the current pageable DPA, CP issues this message.
The user’s reserved pages value is changed. The
command has improved the situation although it has not
fully alleviated the problem. The total reserved pages
value still exceeds the pageable DPA by the number of
pages given in the message (nnnnnnnn).
System Action: The reserved pages value is
changed.
User Response: Issue QUERY RESERVED to identify
the current reserved settings for all users. Reduce the
total reserved amount for users by the value given in
the message (nnnnnnnn). Because the pageable DPA is
constantly changing, it is sufficient to reduce the
reserved amount until this message no longer appears
as the result of the SET RESERVED command.
However, performance can be adversely affected if the
number of reserved pages nears or exceeds the
pageable DPA.
HCP2270I rdev DASD fast write function is active.
Explanation: The device has reported the following
state change:
DASD fast write entered the ACTIVE state
The rdev variable identifies the device reporting the
state change.
