DUMP Host Storage
Usage Notes
Responses
of the storage size specified at system generation and the real storage size).
The address hexloc2 may be from one to sixteen hexadecimal digits; leading
zeros are optional.
Specify END if you want to dump the remaining contents of storage. END is the
default.
A colon (:) means the same as a dash (-) when specifying a range of
addresses.
END
. bytecount
is a hexadecimal integer designating the number of bytes of storage (starting
with the byte at hexloc1) to be dumped to your virtual printer. The sum of
hexloc1 and bytecount must be an address that does not exceed the bounds of
addressable storage (the lesser of the storage size specified at system
generation and the real storage size). The specified byte count must have a
value of at least one and may be from one to sixteen hexadecimal digits.
Leading zeros are optional.
Specify END if you want to dump the remaining contents of storage. END is the
default.
*dumpid
is an asterisk followed by a 1-character to 97-character identifier (truncated to
80 characters for a z/Architecture guest), that is to be assigned to the dump. If
specified, dumpid must be the last operand you enter on the command line.
1. While dumping host storage, the running of a virtual machine or someone using
the STORE HOST command could cause data to be changed. This could create
an inconsistency in the data that is viewed.
2. In a multiprocessor environment, each processor has a prefix register that it
uses to relocate addresses between 0 and X'1FFF' to another page frame in
storage. The prefix register enables each processor to use a different page
frame to avoid conflict with other processors for such activity as interrupt code
recording. Thus, the range 0 through X'1FFF' refers to different areas of
storage, depending on which processor generates the address. All references to
first-level storage are handled as if they were made on the IPL processor.

Response 1:
Hhexloc word1 word2 ... word8 [key ] [*TRANSLATION*]
is the response you receive with the T or N option. The translation is dumped only if
you have also entered the T option and is in either EBCDIC or (if the TX option is
specified) ASCII. The storage key is dumped on the first line, and at every page
boundary.
Response 2:
386 z/VM: CP Commands and Utilities Reference
Xhexlochi_ Storage Key - [Key]
hexloclo word1 word2 word3 word4 [*TRANSLATION*] [Lhexloc]
is the response you receive with the M option. The translation is displayed in either
EBCDIC or (if the MX option is specified) ASCII. The storage key is displayed on
the first line, and at every page boundary.
