Hi,
1) is a easy option to do but there is a catch. The SNMP index can't be
longer than 128 bytes, now if we increase the SU name the component name
will become very big. This will cause the entries in the saAmfSCompCsiTable
table to be not accessible as they will be larger than 128. So we
had to keep the names to the smallest possible. We still can maybe have a
unique marker for openSAF SUs which is small, that should
solve the problem.

Hi,
even if there is no major issue it is still confusing. There is not
better to maintain lists of possible application SUs per node in a cluster. If
OpenSAF components does not behave as "normal" components (from the operator
view) it should be indicated which type of component each component is.
To my opinion there are two solutions:
1) Give the OpenSAF SUs names which could easily be identified e.g..
safSu=SuT_OpenSaf_CPND. In such case the operator/script/program can easily see
that there is no application SI left.
2) Remove OpenSAF SUs from the saAmfSUSITableEntry when the node is
locked i.e let the OpenSAF components behave as normal application components
to the operator.

Ingvar

Hi,
The operator can easily write a script for identifying the
applications SUs on a node. I said SUs not SIs. The operator script need not
track SIs, it
needs to track only application SUs. He can easily search the SUSI
table as you had done with this SU list to see that none have SI assignment.
I don't see any major issue from scripting perspective, yes if he has
to do manually then it is work.

Hi,
I suspected it was designed that way. I think it would be
confusing for the operator to keep lists over SIs which are not excpected to
move. It will be different lists for the two node types and possibly for
different OpenSAF releases. Or (even worse) to keep lists over the applications
SIs. This will also make it difficult to write scripts/programs helping the
operator to perform different tasks in the cluster since the SI lists must be
known to the script/program.

Hi,
It is by design that openSAF components are treated
differently from application. All the AMF commands are applicable to
application components
and not to openSAF components(SG,SU). This is required, if
openSAF goes OOS the node will become un manageable from openSAF perspective.
The operator can get the list of all the application SUs on the
node and verify that they all lost SI assignments to identify if the node lock
is
successful.

LOCK
Hi,
the saAmfSUSITableEntry will newer become empty after a
LOCK operation. The "normal" SI's are moved away but the OpenSAF SI's are not
(see the payload node example below).
This will cause problems for e.g. the operator to
decide when the node is locked since the saAmfSUSITableEntry is assumed to
become emty.
SC_2_1# snmpset -c public -v 2c localhost
saAmfNodeAdminState.\"safNode=PL_2_3\" i 1
SC_2_1# snmpwalk -Os -c public -v 2c localhost
saAmfSUSITableEntry.saAmfSUSISGName | grep safNode=PL_2_3
saAmfSUSISGName."safSu=SuT_CPND,safNode=PL_2_3"."safSi=Si_CPND5" = STRING:
safSg=SG_CPND
saAmfSUSISGName."safSu=SuT_IFND,safNode=PL_2_3"."safSi=Si_IFND5" = STRING:
safSg=SG_IFND
saAmfSUSISGName."safSu=SuT_NCS_PLD,safNode=PL_2_3"."safSi=Si_PLD6" = STRING:
safSg=SG_NCS_ND_PLD
