DUMP PSW
Responses
When the DUMP PSW command is issued from a z/Architecture virtual machine
(with a previous SET PSWTRANS ALL/DISPLAY issued), the 128-bit
z/Architecture format PSW must be converted to a 64-bit ESA/390 format PSW.
This conversion is done as follows:
v bits 0-31 are set to bits 0-31 of the z/Architecture PSW with bit 12 set to 1
and bit 31 set to 0.
v bits 33-63 of the PSW are set to bits 97-127 of the z/Architecture PSW. If bits
64-95 of the z/Architecture PSW are not 0, the PSW is flagged as
non-translatable.
v bit 32 is set as follows:
– if bits 31 and 32 of z/Architecture PSW are both 1, the PSW is flagged as
non-translatable
– if bits 31 and 32 of z/Architecture PSW are both 0, bit 32 of the ESA/390
PSW is set to 0
– if bit 31 of the z/Architecture PSW is 0 and bit 32 is 1, bit 32 of the
ESA/390 PSW is set to 1.
The response to all DUMP options is ″Command complete″. What follows is a
description of the dump information in the generated print file.
Response 1:
The command DUMP PSW with no other options formats the current PSW for a
print file. This is the response you receive on ESA/XC and ESA/390 virtual
machines:
PSW = 03E40000 8003010C
Response 2:
The command DUMP PSW with no other options formats the current PSW for a
print file. This is the response you receive on z/Architecture virtual machines:
PSW = 03EC0000 8003010C PSWG = 03E40000 80000000 00000000 0003010C
Response 3:
The command DUMP PSW with no other options formats the current PSW for a
print file. If the current PSW for a guest machine cannot be converted to a 64-bit
PSW, then this is the response you receive on z/Architecture virtual machines:
PSW = NON TRANSLATABLE PSWG = 03E40000 80000000 00000000 0003010C

The command DUMP PSW ALL formats the old and new PSWs and expands the
interruption code into four hexadecimal digits in front of the old PSWs. nnnn
represents the EC-mode interruption code. The numbers 18, 20, 28... are storage
locations. Each xxxxxxxx xxxxxxxx represents the content of a PSW. This is the
response you receive on ESA/XC and ESA/390 virtual machines:
PSW = xxxxxxxx xxxxxxxx
EXT nnnn 18 OLD xxxxxxxx xxxxxxxx 58 NEW xxxxxxxx xxxxxxxx
SVC nnnn 20 OLD xxxxxxxx xxxxxxxx 60 NEW xxxxxxxx xxxxxxxx
PRG nnnn 28 OLD xxxxxxxx xxxxxxxx 68 NEW xxxxxxxx xxxxxxxx
MCH nnnn 30 OLD xxxxxxxx xxxxxxxx 70 NEW xxxxxxxx xxxxxxxx
I/O nnnn 38 OLD xxxxxxxx xxxxxxxx 78 NEW xxxxxxxx xxxxxxxx
