CP examines the queues and chains of user spool files and locates
where they reside on the spool DASD volumes. If ,"/370 detects a
spooling error, a console message alerts the system operator. CP checks accounting data for irregularities. If any are found, CP displays a message on the system console.
During V"/370 system generation, the installation designates a
console or terminal as the primary operator's system console. CP now
attempts to autoaatically log on the primary systea operator on that
console or terminal. Multiple alternate consoles can be specified in
the RIOGEN macro instruction during system generation. If the
designated V8/370 system console is turned off or not operational, CP automatically atteapts to log on the operator on the first designated
alternate console. If operational, this console is used as the V8/370 primary system console. If not operational and multiple alternate
consoles were specified during system generation, the next alternate
console is accessed. The primary and alternate consoles must be among
the following devices: I A real primary or alternate system console I A locally attached 3270 In addition, the alternate console can be any '8/370 supported remote terminal on a leased line connected to a 270x transmission control unit. Any terainals on switched lines, and leased line terminals connected to 3704/3705s are not supported as primary or alternate '8/370 consoles.
If the alternate devices do not exist, or are not ready, automatic logon
ceases and the VM/370 system enters the disabled wait state. If the
primary or alternate consoles are operational, but some processing error
occurs, manual operator intervention is necessary to bring up the V8/370 system. CP considers the first user to log on VM/370 with privilege
class A as the primary system operator. No other users are accepted on
the system until the primary system operator has successfully logged on.
The system operator's userid, password, and co.mand privilege class or
classes are usually stored on the CP system residence voluae during system installation.
If the system could not perform a warm start because of I/O errors or
invalid data in the warm start area, you can request a checkpoint (CKPT) start. This option attempts to initialize the system using the information that has been dynaaically checkpointed during system operation and stored in the checkpoint area. Spool file chains are
reconstructed; however, the original order of the files is lost.
Accounting and systea message data, recovered under a warm start, is
lost under a checkpoint Ilso, because each spocl buffer aust be
read to reconstruct the record allocation blocks, a checkpoint start
takes longer than a warm start.
If the system cannot perform a checkpoint start because of I/O errors or
invalid data in the checkpoint area, you can request a force (PORCE) start. This option operates like the CKPT start except that any spool
file that contains unreadable or invalid data is dropped from the system. 14 '8/370 Operator's Guide
When the FORCE option is used, you should not allow any users to log
on to the system. The system should be devoted to reclaiming and
putting out as many spool files as possible. When this has been accomplished, the system should be re-initialized using the cold (COLD) start option.
CP automatically logs on the primary system operator as soon as CP polls
the designated system console and finds it ready. Upon successful completion of the IPL and system operator logon, the following message appears: hh:mm:ss LOG!SG- hh:m.:ss EST FRIDAY mm/dd/yy
It indicates the date and the time of the last LOG!SG setting. The
following message then appears and provides a general map of storage
