DASD<br />

Privilege Class: B<br />

Use SET DUMP to assign the unit or units to receive a system abend dump.<br />

DASD<br />

specifies that the system dump is written to one or more disks. The DASD<br />

dump space is released when the dump setting is changed. Clusters are<br />

allocated from spooling space on <strong>CP</strong>-owned DASD devices sufficient to hold<br />

the size dump specified.<br />

rdev...<br />

is the real device number of a real printer, a fully supported tape device, or a<br />

<strong>CP</strong>-owned DASD. If rdev is a <strong>CP</strong>-owned DASD, it can also be a list of real<br />

device numbers. The order in which you specify the DASD is the order in which<br />

they are searched for spooling space to be assigned as system abend dump<br />

space.<br />

<strong>CP</strong><br />

ALL<br />

indicates which pages of storage are to be dumped. Specify <strong>CP</strong> if only storage<br />

locations occupied by the control program are to be dumped. Specify ALL if you<br />

want all real storage dumped. At system initialization, the value is <strong>CP</strong>.<br />

IPL<br />

NOIPL<br />

NOPRINT<br />

indicates that the user wishes to use the Improved Data Recording Capability<br />

(IDRC) hardware compaction capability of the 3480 tape specified in rdev. The<br />

default is no hardware compaction.<br />

IPL<br />

NOIPL<br />

indicates whether the system is to be automatically restarted after a failure. At<br />

system initialization, the value is IPL; if you do not want your system<br />

automatically restarted, you must explicitly change the setting to NOIPL.<br />

NOPRINT<br />

indicates that in the event of a dump device error that causes the dump device<br />

to be set to a printer, the dump is not printed.<br />

OFF<br />

indicates that in the event a dump is attempted, either by a <strong>CP</strong> abend or a<br />

System Restart, no dump will be created.<br />
