The admin command shutdown node (or nodegroup) will hang if component calls
saAmfFinalize during component failover. Trace is attached.
Scenario:
. Issue admin shutdown node
. component rejects quiescing assignment
saAmfCSIQuiescingComplete(SA_AIS_ERR_FAILED_OPERATION)
. component calls saAmfFinalize, finalizing handle
. Due to failure of quiescing assignment, component failover recovery is
started. As result of it, clc cleanup is called.
. The event finalize handle comes before clc cleanup returns ok.
. avnd_comp_clc_terming_cleansucc_hdler() is handling cleanup success case. The
quiescing sequence can't be continued because
avnd_comp_cmplete_all_assignment() currently seems to handle normal case, which
is callback list exist. But the fact component is unregistered, all handles are
deleted by saAmfFinalize. No su_si_oper_done is sent to amfd at the end, thus
the command hang until timeout
Another similiar test is done on amf_demo, which calls saAmfFinalize when
component receives sigterm. The assignment is quiesced then removed
successfully, since amfnd is "aware of " unregistered component during quiesced
assignment sequence.
The quiescing assignment sequence should be aware of unregistered component
this case, in order to avoid hanging shutdown node. Or saAmfFinalize should
return TRY_AGAIN, to be analyzing ...
