For
disabled summary dumps, records are dumped
in the following order:
- If a suspend summary dump was requested but could not be taken,
the system attempts to obtain a disabled summary dump. If this occurs,
an error record is written to that effect. If the system is unable
to obtain a suspend summary dump and a disabled summary dump, then
no summary data is available for the dump.
- The XMEM ASID record is written that gives the ASID that is home,
primary, secondary, and CML (if the CML lock is held).
- The SUMLIST/SUMLSTA/SUMLSTL/SUMLIST64 address ranges
and the PSWREGS data are dumped.
- The PSA, PCCA, LCCA, and LCCX for each processor are dumped.
- The current PCLINK stack (pointed to by PSASEL) is dumped (if
it exists).
- If this is a SLIP request for a dump (ACTION=SVCD), then the SLIP
reg/PSW area (pointed to by the SUMDUMP parameter list SDURGPSA) is
dumped.
The following address ranges are added to the address range
table:
- 4K before and after the PSW address at the time of the SLIP trap.
- 4K before and after each address in the registers at the time
of the SLIP trap.
Duplicate storage is eliminated from this address range
table to reduce the amount of data written to the dump data set.
Note
that if the primary and secondary ASIDs are different, the above address
ranges are added to the table for both ASIDs.
- The IHSA is dumped along with its associated XSB and PCLINK stack.
The PSW and register addresses from the IHSA are added to the range
table. This causes 4K of storage to be dumped around each address.
- The caller's SDWA is dumped, if one exists. The PSW and register
addresses from the SDWA are added to the range table. This causes
4K of storage to be dumped around each address.
- The addresses in the address range table are dumped.
- The super FRR stacks are dumped.
- The global, local, and CPU work save area (WSA) vector tables
are dumped. The save areas pointed to by each of these WSA vector
tables are also dumped.
- 4K of storage on either side of the address portion of the I/O
old PSW, the program check old PSW, the external old PSW, and the
restart old PSW saved in the PSA for all processors, are dumped.
