Dynamic HA Evaluation Guide

Objective

This sample application demonstrates dynamic HA (High Availability) functionality. The application has two components : dhaDemo and dummyComp

• dhaDemo creates/deletes the AMF entities (SG, SI, CSI, SU, Component, etc) dynamically.
• dummyComp is a sample SAF component whose binary(executable) will be used while launching the dynamically created component.

What you will learn

• How to create a 2N model dynamically by creating/deleting various AMF entities using Clovis AMF management APIs related to Dynamic HA.

Building the dynamic HA model (dynamicHaDemo) and deploying runtime images

The Clovis dynamic HA Application is located in : <install_dir>/sdk-5.0/src/examples/dynamicHaDemo

You need to build the model and deploy the runtime images for following nodes : SysCtrlI0, WorkerI0, WorkerI1

It can be done in very similar manner to evaluation system model (eval). For more information about building and deploying a model, please refer to the following section of evalguide:
Building the Evaluation System and Deploying Runtime Images

Code

The application code can be found within the following directory

<project-area_dir>/dynamicHaDemo/src/app/dhaDemo

This sample component is implemented in a single C module (clCompAppMain.c). It uses the AMF dynamic HA apis to create a 2N SG on the fly using the clAmsMgmtCCB apis.

There is an alternate version of this C file: clCompAppMain_batch.c which uses a faster version of these apis using clAmsMgmtCCBBatch apis.

The batch version of the dynamic HA apis are faster as the AMF entity CRUD operatons are batched/cached on the client side before they are committed with clAmsMgmtCCBBatchCommit api.

Both the clAmsMgmtCCB and clAmsMgmtCCBBatch version of the APIs are declared in clAmsMgmtClientApi.h which needs to be included for usage.

Start/Stop the application

The clCompAppAMFCSISet() function is called to set the component's HA state, and the following block of code assigns this requested state to the component, while verbosely detailing this process:

    switch ( haState )
    {
        case SA_AMF_HA_ACTIVE:
        {
            /*
             * AMF has requested application to take the active HA state 
             * for the CSI.
             */

            /*
             * ---BEGIN_APPLICATION_CODE---
             */
            clprintf(CL_LOG_SEV_NOTICE, "Starting dynamic HA demo.");
            clprintf(CL_LOG_SEV_NOTICE, "It will create 2N SG : %sSG", BASE_NAME);
            rc = clDhaDemoStart();
            if(rc != CL_OK)
            {
                clprintf(CL_LOG_SEV_CRITICAL, "Failed to start dynamic HA demo.");
            }

            /*
             * ---End_APPLICATION_CODE---
             */

            saAmfResponse(amfHandle, invocation, SA_AIS_OK);
            break;
        }

  

• clDhaDemoStart() will start the workload in a separate thread to create the AMF entities (SG, SI, CSI, SU, Components, etc) when the HA state of dhaDemo becomes ACTIVE. In this case dhaDemo will be assigned active state when you unlock the SG 'dhaDemoSG'

        case SA_AMF_HA_QUIESCED:
        {
            /*
             * AMF has requested application to quiesce the CSI currently
             * assigned the active or quiescing HA state. The application 
             * must stop work associated with the CSI immediately.
             */

            /*
             * ---BEGIN_APPLICATION_CODE---
             */

            rc = clDhaDemoStop();
            if(rc != CL_OK)
            {
                clprintf(CL_LOG_SEV_CRITICAL, "Failed to stop dynamic HA demo.");
            }

            /*
             * ---END_APPLICATION_CODE---
             */

            saAmfResponse(amfHandle, invocation, SA_AIS_OK);
            break;
        }

  

• clDhaDemoStop() will start the workload in a separate thread to delete the AMF entities (SG, SI, CSI, SU, Components, etc) only if they are already created, when the HA state of dhaDemo becomes QUIESCED or QUIESCING. In this case dhaDemo will be get QUIESCED state when you lock the unlocked SG 'dhaDemoSG'

Usage of AMF management APIs for Dynamic HA

The detailed documentation of AMF management APIs can be found in "OpenClovis API Reference Guide". Please refer "Availability Management Service" section under the High Availability.

How to Run dhaDemo application and What to Observe

We will use the SAFplus Platform Console to manipulate the administrative state of the dhaDemoSG service group.

1. Start the SAFplus Platform on all deployed nodes

    # cd /root/asp/
    # ./etc/init.d/asp start

2. Start the SAFplus Platform Console

    # cd /root/asp/bin
    # ./asp_console

3. Then put the dhaDemoSG service group into lock assignment state using the following commands.

    # cli[Test]-> setc master
    # cli[Test:SysCtrlI0]-> setc cpm
    # cli[Test:SysCtrlI0:CPM]->  amsLockAssignment sg dhaDemoSG
   

   The logs for dhaDemo application will be logged into file /root/asp/var/log/app.0 on node WorkerI0. Viewing these application logs using the tail -f, you should see the following :

   /root/asp/var/log/app.0
   Wed Sep 3 16:03:02 2008 (WorkerI0.21785 : dhaDemo_EO.---.---.00031 : INFO) Component [dhaDemo] : PID [21785]. Initializing Wed Sep 3 16:03:02 2008 (WorkerI0.21785 : dhaDemo_EO.---.---.00032 : INFO) IOC Address  : 0x3 Wed Sep 3 16:03:02 2008 (WorkerI0.21785 : dhaDemo_EO.---.---.00033 : INFO) IOC Port  : 0x80

   
   

4. To create the AMF entities dynamically, unlock the dhaDemoSG service group using the following SAFplus Platform Console command.

    # cli[Test:SysCtrlI0:CPM]->  amsUnlock sg dhaDemoSG
   

   and in the /root/asp/var/log/app.0 file (on node WorkerI0) , we should see:

   /root/asp/var/log/app.0

   Note : The dynamically created component might come up as ACTIVE on WorkerI1 and STANDBY on WorkerI0 or vice versa (depending on the order in which they are launched).

   
   

5. To delete the AMF entities dynamically, lock the dhaDemoSG service group using the following SAFplus Platform Console command.

    # cli[Test:SysCtrlI0:CPM]->  amsLockAssignment sg dhaDemoSG

   These can be watched in a separate terminal window using tail -f <file_name>

6. You can continue to observe this create/delete of AMF entities dynamically by unlocking/locking the SG dhaDemoSG.
   • To unlock the dhaDemoSG using the SAFplus Platform Console (this will create the AMF entities dynamically):

   # cli[Test:SysCtrlI0:CPM]-> amsUnlock sg dhaDemoSG
   

   • To lock the dhaDemoSG using the SAFplus Platform Console (this will delete the AMF entities dynamically):

   # cli[Test:SysCtrlI0:CPM]-> amsLockAssignment sg dhaDemoSG
   

   • To stop the demo and exit, following CLI commands may be used:

   # cli[Test:SysCtrlI0:CPM]-> amsLockAssignment sg dhaDemoSG
   # cli[Test:SysCtrlI0:CPM]-> amsLockInstantiation sg dhaDemoSG
   # cli[Test:SysCtrlI0:CPM]-> bye
   

Summary

This Sample Application has covered basic dynamic HA functionality, with creation/deletion of AMF entities (SG, SI, CSI, SU, Component, etc) using Clovis AMF management APIs.
