Logo 1 Vishal Soni Senior Software Engineer Emerson Network Power – Embedded Computing. OpenSAF MDS, VDS and Build Environment Maintainer. 16/OCT/2008 OpenSAF Startup Procedures

Logo 2 OpenSAF Installation Directories /etc/opt/opensaf – OpenSAF configuration files. (LSB compliance) /opt/opensaf/controller – Main OpenSAF installation directory –scripts – Start/Stop scripts –bin - Binaries –lib/lib64 – Libraries /var/opt/opensaf – For Log files –nidlog – Logging done by NID –Stdouts – Logging done by services started by scap (only stdout) –log – Log generated by DTSv service for individual services. –mdslog – MDS logging

Logo 3 OpenSAF Configuration Files /etc/opt/opensaf/slot_id /etc/opt/opensaf/chassis_id /etc/opt/opensaf/rde.conf export CONTROLLER1= export CONTROLLER2= export RDE_PORT_NUMBER=5003 /etc/opt/opensaf/NCSSystemBOM.xml /var/opt/opensaf/pssv_spcn_list AVM XML AVD XML

Logo 4 OpenSAF Configuration Files (Contd.) /etc/opt/opensaf/nodeinit.conf Format of entries: App-File:AppName:AppType:[CLeanup File]:Time-Out:[Priority]:[n-rspawn]:[n-reset]:[App params]:[Cleanup Parms] Eg. /opt/opensaf/controller/scripts/nid_tipc.sh:TIPC:S:/opt/opensaf/controller/scripts/nid_tipc.s h:4000::2:1:start eth0 1234:stop /etc/opt/opensaf/reboot (soft-link, point it to a script which intimates user with an echo)

Logo 5 OpenSAF Startup Flow How to start OpenSAF node? What is NID? How does NID starts services? Sequence of Service startup TIPC (Installing TIPC + node_id construction) RDE (Negotiating Role) DRBD (optional) SNMP (optional) DTS (Log service) MAS PSS (Reformating PSS store) EDS SNMP-SUBAGT SCAP (Parsing + AMF)

Logo 6 TIPC and NCS node ids TIPC NODE ID format Eg of ncs node-id 0x F  2 chassis_id (fixed at present in MDS)  1 slot_id  F sub_slot_id (not used at present) Corresponding TIPC id will be 0x F in notation

Logo 7 What went wrong ??? Did TIPC Fail to start properly? Check syslog and /var/opt/opensaf/nidlog/NID_TIPC.log Did any other process other than SCAP failed to start? Check /var/opt/opensaf/nidlog/NID_.log Did SCAP failed to start? Check /var/opt/opensaf/nidlog/NID_SCAP.log Do you see some of component started by SCAP failed to start? Check Stdout Logs for that services /var/opt/opensaf/stdouts * Both controllers coming up as Active? Check your RDE configuration, TIPC net-id and TIPC link establishment in syslog. Seeing TIPC link up/down in syslog? Probably you are running your cluster on corporate LAN.

Logo 8 How to Integrate a New Service in OpenSAF framework Type of service Services spawned by NID (pre AMF or pre SCAP) and don’t interact with AMF. Eg. TIPC. –Add startup script. Either same script with start/stop as argument or different scripts. –Start script should write status to NID pipe. –Modify nodeinit.conf. –modify include/nid_api.h & include/nid_err.h to include new service as well as new error code for your service.

Logo 9 How to Integrate a New Service in OpenSAF framework Services spawned by SCAP and interact with AMF. Eg. Any SAF service like CPSv, MQSv etc. –Modify NCSSystemBOM.xml file to add description of your service. –Add Startup and Cleanup script in controller/payload, depending on where your service will be started. –Your service should register with AMF and honour its callbacks like saAmfHealthcheckCallback saAmfCSISetCallback saAmfCSIRemoveCallback saAmfComponentTerminateCallback –To know more, you can take reference of any OpenSAF service.

Logo 10 How to Integrate a New Service in OpenSAF framework Hybrid. Service spawned by NID and at later point of time when AMF is available registers with it. Eg. RDE, DTSv –Add NID startup scripts. Either same script with start/stop as argument or different scripts. –Start script should write status to NID pipe. –Modify nodeinit.conf. –modify include/nid_api.h & include/nid_err.h to include new service as well as new error code for your service. –Modify NCSSystemBOM.xml file to add description of your service. –Add one more set of startup and cleanup script, which will be called by SCAP. –Your service should do AMF registration only after SCAP comes up, so you need a mechanism in your service to wait for SCAP to come up. Generally in Signal and Pipe is used used to do so. –In your code you should wait on a Signal/Pipe for doing AMF registration. –Your Startup script should write on that pipe/send signal, after checking that process is already running.
