I've completed this process for about 30 libraries.
All is working, will have perf numbers to share in a few days.
I have several remaining libraries, all in QSYSLIBL.
I think the only way to move these is to
1) Remove lib from QSYSLIBL
2) IPL
3) Delete/rename lib
4) RSTLIBBRM lib to ASP2.
Repeat process for other libraries
5) Add lib back to QSYSLIBL
6) IPL

After further reading on STRASPBAL, this can only be used to move data
within an ASP, not from ASP1 to ASP2.
Scratch plan B, STRASPBAL.

Chuck,
If I can't move a library from ASP 1 to ASP 2, because of restrictions, I
came up with plan B.
1) Save all my user data.
2) Delete all my user data.
R&D LPAR will only have LIC, OS, and LPP and this point.
3) STRASPBAL TYPE(*ENDALC) UNIT (all the 10k spiny)
4) STRASPBAL TYPE(*MOVDTA) TIMLMT(*NOMAX) PRIORITY(*MEDIUM)
5) Restore all user data to desired ASP.
PLAN C may be another possibility, but I think I need to be on V7R2 for
this.
Backup, Recovery, and Media Services (BRMS) modernizes its storage tiering
support to now include IFS, IASP, and tiering within an ASP. The migration
was originally required to be between ASPs, but now policies can be set up
to enable migration of database files between faster and slower disks in
the same ASP. Unlike typical Easy Tier(r) functions that move small pieces
of data to and from faster storage based on patterns of usage, the BRMS
storage tiering function operates at a file or library level to help
optimize the value of using SSDs. A system administrator can choose to keep
on SSD a file or library that may currently have a lot of low latency
pieces of data, because of knowledge that the whole file or library will be
needed in the future. This aspect can be useful for month-end or
quarter-end processing. The BRMS migration function integrates well with
existing BRMS policies that allow low-use files and libraries on slower
disk to eventually be automatically archived
to tape.

immediately comes to mind.
I'd also like to move some system libraries, SYS, QSYS, QSYS2, QUSRSYS
and QGPL. But I know I can't restore these.
Not sure what library SYS is; perhaps meaning to imply, all of the
quasi-system libraries with naming SYS*, e.g. SYSIBM?
AFaIK the system still has a restriction [though not explicitly
enforced] requiring that those [non-LPP] system libraries [and most|all
quasi-system libraries] must reside on the primary\*SYSBAS; i.e. must
reside on Basic User ASP(1), both to ensure proper function and to be
considered a /supported/ environment. Note: Each Independent ASP (iASP)
[i.e. not the Basic User ASPs of *SYSBAS] already will have their own copy
of [some of those] libraries with naming that reflects the iASP number,
e.g. QSYS200033 for iASP=33, and *SYSBAS minimally needs those /system/
libraries to reside in *SYSBAS [even if possibly or if even plausibly, in a
Basic User ASP other than ASP(1)].
MOVOBJ allows you to move most object types from one ASP to another
ASP. *LIB however is excluded.
While the Move Object (MOVOBJ) and the equivalent API (QLIRNMO) offer
ASP-related parameters for designating where to search for the named
libraries [From ASP device (ASPDEV) and To ASP device (TOASPDEV)], I do not
expect the capability exists for that feature to "move most object types
from one ASP to another", at least from what I recall for Basic User ASPs
1-32. I am not aware that a request to _move_ an object can\will effect
reassignment of the storage of the object to that of the target Basic User
ASP; i.e. AFaIK the _move_ capability remains essentially, just an address
reassignment, merely giving addressability to the object via a different
library name in the same ASP, and is incapable of reassigning the actual
storage of that object because no LIC [storage management] method exists to
be invoked against an object to make a change of the storage from one ASP
to another. The following quote, from the following link, seems to agree:
"You cannot directly move objec
ts between ASPs because the Move Object (MOVOBJ) command and the Move
Document (MOVDOC) command move only the pointer to the object.
They do not physically copy data from one location to another."

Recovering your system -> Working with auxiliary storage pools ->
Transferring objects between ASPs [

]
_Transferring objects between auxiliary storage pools_ "You can move
entire libraries or folders from one auxiliary storage pools (ASPs) to
another. Special procedures are used to move a library that contains
journals because a journal and the journaled objects must be in the same
basic user ASP or the same independent ASP group.
The Working with nonlibrary user auxiliary storage pools topic discusses
the procedures for working with nonlibrary user ASPs.
You cannot directly move objects between ASPs because the Move Object
(MOVOBJ) command and the Move Document (MOVDOC) command move only the
pointer to the object. They do not physically copy data from one location
to another. In general, follow these steps to move an object to a different
ASP:
* Sign as QSECOFR.
* Save the object and its private authorities by specifying the
PVTAUT(*YES) parameter.
* Delete the object from the system. If you are transferring the
object from one independent ASP to another independent ASP, this step is
not required.
* Restore the object to the target ASP by using the RSTASP parameter
on the RSTxxx command. If you are restoring objects to an independent ASP,
use the RSTASPDEV parameter. If you need to restore the private authorities
of the object, use the PVTAUT(*YES) parameter.
..."

]
Transferring journals and objects to a different auxiliary storage pool
"If you use a library user auxiliary storage pool (ASP), both the objects
you are journaling and the journal must be in the same ASP. ..."
Yet, I find that the MOVOBJ command help does show an example seeming
to imply the ability to move an object from one iASP to another iASP,
despite failing to explicitly note they are both Independent ASPs; i.e.
the following, which I had no knowledge was supported, nor how that is
possible with just the Modify Address (MODADR) MI instruction:
Example 3: Moving an Object from a Library in an Independent
Auxiliary Storage Pool (ASP) to a Library in a different ASP.
MOVOBJ OBJ(INVENTORY/MONTHLY) OBJTYPE(*PGM)
TOLIB(WINVENTORY) ASPDEV(SALES) TOASPDEV(WSALES)
Hmmm, OK; perhaps a _move_ is not always a literal /move/, and instead
is a /copy/, effected by save\restore. In contradiction to the implication
in the above doc, the Move Object (MOVOBJ) command [though the API docs for
that effect seem more sparse] apparently actually effects a SAVOBJ\RSTOBJ
to /mimic/ a move, so as to enable spanning ASPs by making a /copy/ of the
storage into another ASP. But done so, with some stated caveats [much the
same as those for the Move Library to ASP
(QHSMMOVL) API], whereby the effects for spanning an ASP [and seems not to
be limited to iASPs only] contradicts an expectation of the typical _move_
request, because the actual implementation is via the save\restore [and
just like the Move Library to ASP (QHSMMOVL) API, operating without the
QDTA(*DTAQ), but with PVTAUT(*YES)]. Still, that does not magically
resolve the restrictions such as journaled objects no longer being
journaled and database file dependencies that can not span ASPs [per msg
CPF327C].
