#173 protection group callback is giving null info when component moves from quiesced to no redundancy

[Nagendra Kumar]

Migrated from http://devel.opensaf.org/ticket/2034

Brought up 2 SU's in 2N model.

Protection group tracking is started with SA_TRACK_CHANGES.
When standby SU lock followed by active SU lock, three protection group callbacks are expected,

1 ) For standby SU lock,

numberOfmembers -> 1
notificatioBuffer->numberOfItems->2
standbyComponent's info filled with SA_AMF_PROTECTION_GROUP_REMOVED change and with haState as zero

2) for active SU lock, active to quiesced

numberOfmembers -> 1
notificatioBuffer->numberOfItems->1
quiesced component's info filled with SA_AMF_PROTECTION_GROUP_STATE_CHANGE and with haState as QUIESCED

3) For quiesced to no redundancy change,

numberOfmembers -> 0
notificatioBuffer->numberOfItems->1
old quiesced's info filled with SA_AMF_PROTECTION_GROUP_REMOVED change and with haState as zero

In the current implementation, the callback info in the third step is not filled with old quiesced's info. numberOfItems is given as zero.

Can you please explain step 3, I don't really understand quiesced => no redundancy. Are you doing an "amf-adm lock" on SI?

Not able to reproduce this. Please let me know what I am missing/not understand. Running demo app, 2N, SA_TRACK_CHANGES. Startup:

ha state = quiesced(3) during SA_AMF_PROTECTION_GROUP_STATE_CHANGE then when change is SA_AMF_PROTECTION_GROUP_REMOVED numberOfItems=0.

when standby is left from the group, following info is generated in the callback :

members=1, items=2

---

amf_demo[436]: item=0, change=1, comp=safComp=AmfDemo?,safSu=SU1,safSg=AmfDemo?,safApp=AmfDemo?1, haState=1, rank=1
amf_demo[436]: item=1, change=3, comp=safComp=AmfDemo?,safSu=SU2,safSg=AmfDemo?,safApp=AmfDemo?1, haState=0, rank=2

---

change about standby SU is set to SA_AMF_PROTECTION_GROUP_REMOVED and haState is set to zero.

But when quisced is left from the group, following info should be generated in the callback

members=0, items=1

---

amf_demo[436]: item=0, change=3, comp=safComp=AmfDemo?,safSu=SU1,safSg=AmfDemo?,safApp=AmfDemo?1, haState=0, rank=1

---

Also when change=3 ( SA_AMF_PROTECTION_GROUP_REMOVED), members will be zero, but not the numberOfItems. AMF need to send that info abt the member removal.

The agent who tracks the group doesn't have the information that the quiseced has left the group.
It will still have the info that active have gone to quisced state.
