Privilege Class: B
Use QUERY DUMP to display the following:
v The device type and unit or units assigned to receive CP abnormal termination
dumps
v The current settings of the DUMP options.
1. For DASD only, if you have identified more than one device to receive CP
dumps or CP has obtained DASD dump space from more than one device
during system initialization and operation, CP responds with the device type
DASD, the real device numbers, and the pages allocated from each.
2. If the system was unable to find sufficient DASD storage, it responds with
PRINTER. PRINTER indicates that, at the time z/VM is ready to create the
dump, it assigns the dump to the first printer available in the order in which the
printers were defined at initialization. If no printers are available when z/VM is
ready to create the dump, the dump is not created.
Response 1:
{type rdev} dump unit {CP } {IPL } [pages nnnn] [NOPRINT]
{Printer } {ALL} {NOIPL}
type rdev
indicates the device type and the real device number of the dump device. type
can be DASD, TAPE, or PRINTER.
PRINTER
indicates that no dump device has been assigned and that CP was unable to
find enough contiguous DASD space at initialization to assign a DASD dump
receiver. By default, when z/VM is ready to create the dump, it assigns the
dump to the first printer available in the order in which the printers were defined
at initialization. If no printer is available when CP is ready to create the dump,
no dump is created.
CP
ALL
indicates whether CP-owned pages and free storage are included in your dump,
or all pages in real storage are included in your dump.
IPL
NOIPL
indicates whether the system automatically restarts when the dump is
completed. NOIPL indicates that the system enters a wait state upon
completion of the dump.
