Comments (indicate scope for each "y" above):
---------------------------------------------
I didn't want to handle the deletion in this bug.  There is already code in
ccb_completed_modify_hdlr that looks at DELETION and just continues the loop
without doing anything.  So, no deletion is being handled there at all.  Are
there other attributes we want to treat this way?  Handling the deletion of
saAmfSGNumPrefActiveSUs in ccb_completed_modify_hdlr cleanly will require some
reorg of ccb_completed_modify_hdlr which I think is outside the scope of this
bug.

        amfd: allow increase of saAmfSGNumPrefActiveSUs for N+M SG while 
UNLOCKED
        [#871]

        ccb_completed_modify_hdlr: Attribute 'saAmfSGNumPrefActiveSUs' cannot be
        modified when SG is unlocked

        OpenSAF disallows changing saAmfSGNumPrefActiveSUs while the SG is 
UNLOCKED.
        This prevents in-service capacity upgrade for N+M models, which is not
        desirable.

        This change allows saAmfSGNumPrefActiveSUs to be increased for N+M 
models,
        as long as there are instantiated spare SUs equal to the amount of the
        increase. These instantiated spare SUs will then be assigned ACTIVE, and
        their corresponding CSIs will be assigned to the STANDBY.


Complete diffstat:

 osaf/services/saf/amf/amfd/sg.cc |  42 ++++++++++++++++++++++++++++++++++++++++
 1 files changed, 42 insertions(+), 0 deletions(-)


Testing Commands:
-----------------
1) create an N+M SG, with at least 3 SUs, and have saAmfSGNumPrefActiveSUs be 1
2) make sure the SG is UNLOCKED
3) immcfg -a saAmfSGNumPrefActiveSUs=2 safSg=XXX,...

Testing, Expected Results:
--------------------------
The change should be allowed, and the instantiated spare SU is now active.

Reviewer Checklist:
-------------------
[Submitters: make sure that your review doesn't trigger any checkmarks!]


Your checkin has not passed review because (see checked entries):

___ Your RR template is generally incomplete; it has too many blank entries
    that need proper data filled in.

___ You have failed to nominate the proper persons for review and push.

___ Your patches do not have proper short+long header

___ You have grammar/spelling in your header that is unacceptable.

___ You have exceeded a sensible line length in your headers/comments/text.

___ You have failed to put in a proper Trac Ticket # into your commits.

___ You have incorrectly put/left internal data in your comments/files
    (i.e. internal bug tracking tool IDs, product names etc)

___ You have not given any evidence of testing beyond basic build tests.
    Demonstrate some level of runtime or other sanity testing.

___ You have ^M present in some of your files. These have to be removed.

___ You have needlessly changed whitespace or added whitespace crimes
    like trailing spaces, or spaces before tabs.

___ You have mixed real technical changes with whitespace and other
    cosmetic code cleanup changes. These have to be separate commits.

___ You need to refactor your submission into logical chunks; there is
    too much content into a single commit.

___ You have extraneous garbage in your review (merge commits etc)

___ You have giant attachments which should never have been sent;
    Instead you should place your content in a public tree to be pulled.

___ You have too many commits attached to an e-mail; resend as threaded
    commits, or place in a public tree for a pull.

___ You have resent this content multiple times without a clear indication
    of what has changed between each re-send.

___ You have failed to adequately and individually address all of the
    comments and change requests that were proposed in the initial review.

___ You have a misconfigured ~/.hgrc file (i.e. username, email etc)

___ Your computer have a badly configured date and time; confusing the
    the threaded patch review.

___ Your changes affect IPC mechanism, and you don't present any results
    for in-service upgradability test.

___ Your changes affect user manual and documentation, your patch series
    do not contain the patch that updates the Doxygen manual.
