0000 0 Structure RLOBK Live Guest Relocation control block
General Info about relocation
0000 0 Address 8 RLONEXT SOURCE: Pointer to next RLOBK in
the system RLOBK list
(SYSRLOBKS). The end of the list
is denoted by a 0000 value DEST:
Same as source.
0008 8 Character 8 * RESERVED FOR IBM USE
0010 16 Address 4 RLOVMDBK SOURCE: Origin VMDBK address for
the guest being relocated. DEST:
Same as source. Only valid after
the 'build skeleton' phase of
relocation and no longer valid
after RLOWORKCT goes to 0. This
pointer is guaranteed to be valid
by incrementing the VMDBK's work
count (VMDDFRWK) in 'build
skeleton' and decrementing it
when RLOWORKCT goes to 0.
0014 20 Address 4 RLOUSRBK SOURCE: not used DEST: holds
pointer to former stand alone
USRBK during final resumption of
guest if one was found by
HCPUSRRI. If a stand alone USRBK
was not found by HCPUSRRI, this
field remains 0. This pointer is
valid over losses of control
because the USRBK is not in the
USRBK chain or userid hash table.
This is the only pointer to this
"inactive" USRBK which has
USRCHAIN=0.
0018 24 Character 8 RLOUSER SOURCE: USERID of the guest being
moved, canceled, modified or
status-ed. This is filled in
during syntax parsing. DEST: Same
as source.
0020 32 Character 8 RLOSRCSYS SOURCE: System ID of the system
where the guest is relocating
from. This is filled in during
syntax parsing. DEST: Same as
source. Filled in when
destination is notified of
incoming relocation (HCPRLORR).
0028 40 Character 8 RLODSTSYS SOURCE: SystemID of the system
where the guest is being
relocated to. This is filled in
during syntax parsing. DEST: Same
as source. Filled in when
destination is notified of
incoming relocation (HCPRLORR).
0030 48 Character 8 RLOISSUER SOURCE: UserID of user who
initiated the relocation by
issuing the VMRELOC move command.
Filled in during syntax parsing.
DEST: Same as source. Filled in
when destination is notified of
incoming relocation (HCPRLORR).
0038 56 Dbl-Word 8 RLOWORKCT Work counter. This should be
incremented by any task that is
doing a job related to this
relocation and will need to
access this RLOBK in the future.
We do this to ensure that the
RLOBK will not be destroyed while
it is still being referenced.
Code that destroys the RLOBK will
first check to make sure that
this counter is 0. For example,
it is set to 1 when we start the
relocation because the main
relocation task will need this
RLOBK for many things over the
course of the relocation. If, at
some point during the relocation,
a user issues a VMRELOCATE STATUS
command, that command will
increment this counter, then
output the status information
found in this RLOBK, and then
finally decrement this counter.
This field is serialized via SYSRLOLCK
and CS. SYSRLOLCK must be held either
shared or exclusive to modify this
field. This field should always be
modified using compare and swap logic.
SOURCE: On the source side, this
counter will be incremented once when
we create the RLOBK, once when we
start the HCPRLUCC thread, and once
for each execution of the following:
VMRELO STATUS, VMRELO MODIFY, VMRELO
CANCEL command. When the commands
finish up they will decrement the
work counter. We do not need to have
the three threads (I/O config reloc-
ation, Penult. Mem copy, and CPU
config relocation) increment the work
counter because they all come back to
HCPRLOMV and HCPRLOMV does not
continue until all three are done.
Since HCPRLOMV is the only place that
the relocation is actually terminated we
can be sure that none of the three
threads will be active when we try to
terminate the relocation and kill the
RLOBK.
DEST: On the destination
the work counter is 1 when we start a
new relocation. From there, we want to
increment it for each outstanding
thread that does some work using the
RLOBK. A "thread" in this case is
created when we create a socket
connecting the source and destination.
Since the destination simply completes
tasks that the source requests, a
request will come in, the destination
will do some stuff, and return a reply.
At some point the socket being used for
the thread will close which effectively
ends that thread. So we increment the
counter for each socket created on the
destination and we decrement it when
we close a socket. The final main
socket (the one used to start the MOVE)
will be closed during cleanup.
0040 64 Dbl-Word 8 RLOSAVPTR SOURCE: Just before the
trifurcation phase of relocation,
HCPRLOMV's save area address is
stored here. Since the three
threads started (HCPRLOT1,
HCPRLOT2 and HCPRLOT3) are
entered via GOTO they do not have
a save area. To avoid a situation
where one of the threads modifies
the save area of HCPRLOMV we use
this field to remember the save
area address, zero it out before
calling the threads, then restore
it after the threads complete.
DEST: Not used.
0048 72 Dbl-Word 8 RLOS2SVG Pointer to the savearea used for
getting CFM for the skeleton
VMDBK on the destination system
0050 80 Character 8 RLOSECU SOURCE: Not used DEST: USERID of
the relocating guest's secondary
user
0058 88 Character 8 RLOGNMxx SOURCE: Not used DEST: Holds the
generated LOGNMxxx userid once
the receptor guest's VMDBK has
been created.
0060 96 Signed 2 RLOSSLOT SOURCE: Holds the SSI member slot
number of the relocating guest's
destination system. DEST: Holds
the SSI member slot number of the
relocating guest's source system
0062 98 Signed 2 * Reserved for IBM use
0064 100 Address 4 RLOATVMD SOURCE: VMDBK address of the
VMRELOCATE command issuer when
issued via the AT command. This
is used to route command
responses in synchronous command
code paths. DEST: Not used.
0068 104 Dbl-Word 8 RLOCCTRQ SOURCE: TRQBK for HCPRLUCC,
cleanup check. HCPRLUCC is called
in HCPRLOMV. It checks to see if
the user issued CPHX or we
exceeded the max quiesce or max
total time. If so then it flips
the terminate (and maybe cancel)
bit to cause the relocation to
terminate. This TRQBK is used to
schedule HCPRLUCC to run once a
second to perform these checks.
DEST: Not used.
RLOFLGWRD Section
This section defines 4 bytes of flags that are serialized
via compare and swap. Not all of these bits need to be
modified via compare and swap. See the comments for
specific bits for details.
0070 112 Signed 4 RLOFLGWRD (0) Beginning of 4 bytes of flags. We
use this field so we can do
compare and swaps on the needed
bits in RLOTRMFL. We need a
fullword because the CS
instruction works with a fullword
sized value.
0070 112 Bitstring 1 RLOGFLGS General flags associated with
this relocation.
1... .... RLOSRCMOV X'80' RLOSRCMOV SOURCE: This bit
is on. Indicates that this is the
source system for this
relocation. DEST: This bit is
off. Indicates that this is the
destination system for this
relocation. NOTES : Because this
bit is only set during command
parsing (before anything else is
using the RLOBK) we do not use CS
to turn this bit on.
.1.. .... RLODONEIO X'40' RLODONEIO SOURCE: Bit is
turned on to indicate that the
asynchronous thread responsible
for completing I/O relocation has
completed. DEST: Not used.
..1. .... RLODONEMC X'20' RLODONEMC SOURCE: Bit is
turned on to indicate th the
asynchronous thread responsible
for completing the penultimate
memory copy has completed. DEST:
Not used.
...1 .... RLODONEST X'10' RLODONEST SOURCE: Bit is
turned on to indicate th the
asynchronous thread responsible
for completing the state
relocation and final VSIM
eligibility checks has completed.
DEST: Not used.
.... 1... RLOBUSRS X'08' RLOBUSRS SOURCE: Not used.
DEST: Bumped SYSUSRS - Bit is
turned on to indicate that the
VSIM Eligibility tests have
bumped the maximum users count
(SYSUSRS) on the destination
system. Incrementing this field
reserves a slot on the
destination side for the userid
being relocated. This needs to be
remembered so that later
relocation functions do not
increment SYSUSRS again and
cancel/ terminate knows when to
decrement SYSUSRS. NOTES : This
bit is set/cleared on the
destination in places where no
other thread related to this
relocation will be running.
Therefore CS logic is not needed.
Those places are as follows:
HCPRLEVD - Set. HCPRLURD - Set.
Cleared if RLURD fails
.... .1.. RLOCALLCD X'04' RLOCALLCD SOURCE: This bit
exists because we need to call
HCPRLICD during trifurcation but
only after both threads RLOT1 and
RLOT2 have completed their work.
Each of those threads will, upon
completion of all their other
work, check this bit. The first
of the threads to check it will
see that this bit is OFF and will
turn it on using CS. The 2nd of
the threads to check it will see
that it is ON and it will call
HCPRLICD. DEST: Not used.
0071 113 Bitstring 1 RLOTRMFL Flags governing the canceling and
termination of a VMRELO MOVE
command.
1... .... RLOCANCEL X'80' RLOCANCEL SOURCE: Cancel
bit. Turned on when a user
decides to cancel the relocation
via the VMRELOCATE CANCEL command
or via CPHX. When setting the
cancel bit the terminate bit must
also be set. DEST: The cancel bit
is set on the destination but
since all of the work done on the
destination is kicked off by
requests (there is no main thread
that checks the cancel/terminate
bits and notices them on) this
bit is set for informational
purposes only. The destination
system kicks off cleanup
processing when the main socket
is closed.
.1.. .... RLOTERM X'40' RLOTERM SOURCE: Terminate
bit. Turned on when an error
occurs. Turning this bit on will
cause the relocation to be
canceled. Relocation code checks
this bit often and bails out if
it's on. Sub-functions of
relocation called by HCPRLOMV do
not need to turn this bit on if
they have an error. HCPRLOMV will
handle setting the terminate bit
if a subfunction fails (returns
non-zero) After the terminate bit
is set, the RLOFINCD field *must*
be set to a valid code explaining
why the relocation has been
stopped. DEST: The terminate bit
is set on the destination
however, like the cancel bit, we
do not rely on it being set to
kick off cleanup/error
processing. We kick off cleanup
processing when the main socket
is closed. Termination of a
relocation must be done in
coordination with the source
system. Anyone who is writing a
routine on the destination that
encounters an unrecoverable error
should send a failure indicator
back to the source system who is
presumably awaiting some kind of
response from the routine running
on the destination. In the event
that the source is not waiting
for a reply from the destination
then entry point HCPRLOAT can be
used (instead of setting the
RLOTERM bit) to ask the source
system to terminate.
..1. .... RLOPNORET X'20' RLOPNORET SOURCE: Bit is
turned on to indicate th this
relocation has reached the point
of no return. This means the
relocation can't be stopped
because we've performed
irreversible actions on this
guest. Canceling at this point
would be fatal for the guest
being relocated. A point of no
return is currently needed
because of I/O virtual
reserve/release actions that are
not reversible. These actions are
held off until the last possible
second to minimize any adverse
impact to the guest. This bit
gets set just before the 'resume
guest' stage in HCPRLURS. DEST:
Same as source. Set in HCPRLURD.
0072 114 Bitstring 1 RLOFINCD SOURCE: Reason code for command
end. This field should be set
wherever the terminate bit is
turned on. This field is
initialized to xFF early on in
relocation because x00 is a valid
value (RLOFCMP). HCPRLO sets this
field when it detects an
error/cancellation or when the
relocation has completed.
relocation error/cleanup code
relies on this this field.
Serialization NOTE: You are only
allowed to set RLOFINCD after
you've set the terminate bit for
this relocation. The terminate
bit serializes writes to FINCD
such that if several failures
happen at once then only the
thread who actually flips the
terminate bit may set RLOFINCD.
DEST: Set in HCPRLODR when the
destination is told to terminate
by the source system.
00000000 RLOFCMP 0 RLOFCMP Relocation completed

00000001 RLOFCAN 1 RLOFCAN Relocation ended by
user command (VMRELOCATE CANCEL)
00000002 RLOFCPHX 2 RLOFCPHX Relocation ended by
user cmd (CPHX)
00000003 RLOFCOM 3 RLOFCOM Relocation ended due to
communications failure (ISFC
socket lost)
00000004 RLOFMXT 4 RLOFMXT Relocation ended due to
MAXTOTAL time limit exceeded
00000005 RLOFMXQ 5 RLOFMXQ Relocation ended due to
MAXQUIESCE time limit exceeded
00000006 RLOFELG 6 RLOFELG Relocation ended due to
eligibility check failure
00000007 RLOFVMA 7 RLOFVMA Relocation ended due to
incompatible virtual machine

00000009 RLOFEXT 9 RLOFEXT CP Exit (custom elig
check) failed.
0000000A RLOFTST 10 RLOFTST VMRELOC TEST operation
has completed w/out error. If the
test operation DID have an error
then RLOFINCD would get set to
RLOFELG.
0000000B RLOFEXRC 11 RLOFEXRC CP Exit returned bad
RC.
0000000C RLOFDEST 12 RLOFDEST Relocation ended
because the destination could not
continue. Termination messages
describe the error condition.
0073 115 Bitstring 1 * RESERVED (part of RLOFLGWRD)
0074 116 Bitstring 1 RLOGFLG2 General relocation flags NOTES :
The bits in this byte are
serialized by ONLY modifying them
in code paths that run serially
within the relocation, meaning
that two pieces of code that
update a bit in this byte cannot
be allowed to run concurrently.
1... .... RLOCFMST X'80' RLOCFMST SOURCE: This bit
indicates that there is an
outstanding request for CFM
serialization for this
relocation. It is used in
HCPRLHIP to determine when it can
return to its caller. See
HCPRLHIP's prologue for details.
To ensure proper serialization,
only access this bit in code
paths where no other code path
can be accessing it at the same
time as we do not currently
protect it in any other way.
DEST: This bit indicates that
there is an outstanding request
for CFM serialization for this
relocation.
.1.. .... RLOTBOMB X'40' RLOTBOMB SOURCE: This bit
indicates that the relocating
user's timebomb was dequeued and
now contains a residue in
TRQBVAL. DEST: Not used.
..1. .... RLOSLEEP X'20' RLOSLEEP SOURCE: This bit
indicates that the relocating
user's sleep timer needs to be
reactivated if relocation fails.
DEST: Not used.
...1 .... RLOGSCOM X'10' RLOGSCOM SOURCE: Not used.
DEST: This bit is set in HCPRLOST
to indicate a communications
error was encountered while
trying to update RLOBK status via
HCPRLOGS. This bit is used in the
status output loop of HCPRLOGS to
detect and report this
communication error.
.... 1... RLOCCRUN X'08' RLOCCRUN SOURCE: This bit
is set when the HCPRLUCC thread
is running and is checking for
CPHX and expired timeouts and
such. It is turned off when this
thread is finished and will never
again reference this relocation's
RLOBK. As per LGR design, the
VSIM cleanup routine will not
return until this bit is off,
thereby signalling that the
HCPRLUCC thread was never needed
or has completed. DEST: Not used.
.... .1.. RLOMSTRD X'04' RLOMSTRD SOURCE: This bit
is turned on as the last step in
the build skeleton phase. It
signifies that the setup work
(things like getting connected
and doing eligibility checks) is
complete and the relocation has
actually started. We check this
to determine whether or not to
put out the *VMEVENT/Monitor
records that signify that the
relocation has ended. We only
want to put these ending records
out if we put out the
corresponding starting records.
We put out the starting records
when we set this bit. DEST: Not
used.
.... ..1. RLOISASN X'02' RLOISASN SOURCE: This
relocation has gone asynchronous.
We set this just before returning
to the command issuer for an
asynchronous relocation. This bit
being on will affect how messages
are handled. If the bit is ON
then that means no user is
actively executing a command that
is waiting for responses from
this relocation, and in that case
we will NOT dispatch on the
command issuer's VMDBK for
message output. The side effect
is that the messages will not
enter the DIAG 8 buffer but will
go directly to the screen. If
this bit is off then we will
always dispatch on the command
issuer's VMDBK for message output
meaning any output will go into
the command issuer's DIAG 8
output buffer which means it will
be captured for things like the
PIPE CP stage. If we did not use
this bit and we dispatched on the
command issuer in the
asynchronous case we might
accidentally insert some output
in the DIAG 8 output buffer for
some other ongoing command. DEST:
Not used.
.... ...1 RLOATCMD X'01' RLOATCMD SOURCE: This
relocation was initiated with the
AT command. This is used to help
determine if and how command
responses are presented to the
VMRELOCATE command issuer when it
is issued via the AT command.
DEST: Not used.
0075 117 Bitstring 1 RLOEXRC SOURCE: CP Exit call status. We
use CP Exit 1230 to allow user to
specify custom eligiblity checks.
This field stores the exit's
return code. Since we call the
exit twice during a normal
relocation the first value gets
overwritten when the second call
is made. DEST: Not used.
00000000 RLOEXOK 0 RLOEXOK Custom elig checks
passed.
00000004 RLOEXELG 4 RLOEXELG Custom elig checks
failed. Exit after CP's elig
checks.
00000008 RLOEXIMED 8 RLOEXIMED Custom elig checks
failed. Exit immediately.
0076 118 Bitstring 1 RLOEXCNT SOURCE: Number of times we've
called custom elig checks CP exit
for this relocation. Valid values
are 0, 1, 2. DEST: Not used.
0077 119 Bitstring 1 RLOGFLG3 General relocation flags NOTES :
The bits in this byte are
serialized by ONLY modifying them
in code paths that run serially
within the relocation, meaning
that two pieces of code that
update a bit in this byte cannot
be allowed to run concurrently.
1... .... RLOARDMG X'80' RLOARDMG SOURCE:
ARD-must-go bit indicates that
the architecture eligibility
checks have been done and the
guest may be relocated but the
guest's current ARD must be moved
along with the guest to the
destination system. DEST: Not
used.
.1.. .... RLOCAPCH X'40' RLOCAPCH SOURCE: Not used
DEST: Indicates whether a
capability change indication
should be given to the guest base
VMDBK on destination system after
the relocation completes.
0078 120 Character 8 RLOCNCLR SOURCE: USERID of guest who
canceled this relocation either
via CPHX or VMRELOCATE CANCEL.
This is used during output of
cancel message 7174R. DEST: Same
as source. This gets set by the
cancel command if the cancel
originates from the destination.
If the cancel originates from the
source then this field does NOT
get set because a message is not
delivered stating that the
relocation was canceled.
0080 128 Character 8 RLOCNSYS SOURCE: System ID where the
canceler of this relocation was
logged on when he issued the
cancel request. This field is
used during output of cancel
message 7174R. DEST: Same as
source. This gets set by the
cancel command if the cancel
originates from the destination.
If the cancel originates from the
source then this field does NOT
get set because a message is not
delivered stating that the
relocation was canceled.
Work counter tracking fields
0088 136 Signed 4 RLOWILST (20) SOURCE: List of places that
called HCPRLHFR and thereby
caused this RLOBK's work counter
to be incremented. Each item on
the list is a 4 byte address of
the caller of HCPRLHFR. If we
attempt to add an item beyond the

we'll pass to ISFC's receive
function that will force the
receive to return to us every n
seconds so we can check to see if
someone has canceled the

end up waiting for a long running

fact we do end up in that
situation then any cancel request
will be ignored until that long

Return codes used to return status information to HCPRLOMV
and HCPRLOTS. All subfunctions called from HCPRLOMV should
return one of these codes in R15 to inform RLOMV of any
errors that might have occurred during that subfunction's
processing. In the event that two types of errors occurred
(for example you had an eligibility check failure and a
communication failure) then you should return the highest
applicable return code (16 i.e: RLORCCOM in our example).
NOTES : Since HCPRLOMV runs only on the source system these
codes are only valid on the source system.

obtained globally during the time
the relocation was occurring. It
is verified during the second set
of eligibility checks and again
after the VAAXLK lock is obtained
locally on the destination system
during guest state relocation.

The following fields are used to hold time stamps to assist
in debugging. They are copied into relevant trace entries
cut when the associated event completes. This allows the
debugger to determine the duration of such an event.
This approach was taken to reduce the number of trace
entries given the size of the functional trace table is
limited. The RLOBK is used to hold these time stamps
(rather than SVGWRKs local to the using entry point)
because the RLOBK is preserved for a while after the
relocation completes and can easily be located on a live
system without requiring a dump.

Processing error codes are used to uniquely identify where
an unexpected error was detected. There should be one and
only one reference to any error code.
Code assignments by subsystem:
2- 99 - Storage Management
100-169 - VSIM
170-255 - I/O
Processing errors that originate within RDP handling
routines will contain an additional suffix with the
format "-n", where n is one of the RDP types assigned to
RLOSTYPE. Since all RDP types use common code for data
transfer, the suffix serves to identify which RDP type
encountered the error.
