I had 2 organization in Hyperledger Fabric blockchain network initially. Recently I added one more organization on a different host using swarm. When I try to invoke chaincode from 1st or 2nd organization then it's working fine and I can see the updated transaction from org3. But when I invoke a transaction from org3, I am getting the following error.

"[2019-02-06 06:44:21.895] [ERROR] invoke - The transaction was invalid, code = ENDORSEMENT_POLICY_FAILURE"

Initially, chaincode was initiated using the following policy. -P "OR ('Org1MSP.peer','Org2MSP.peer')"

So I think I will have to update existing endorsement policy to include org3.

Could anyone help to modify existing endorsement policy or to resolve the issue?

The way to upgrade the chaincode is as followed:

  • Increment the version of ccRequest containing ccPackage

  • Re-Install the ccRequest on all orgs in the channel.

    Ex: peer chaincode install -n mycc -v 2.0 -p github.com/chaincode/chaincode_example02/go/

  • Create new ccPolicy with correct rules containing required orgs as endorsers.

  • Upgrade the chaincode by running upgradeCC command

    Ex: peer chaincode upgrade -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 2.0 -c '{"Args":["init","a","90","b","210"]}' -P "OR ('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')"

    • Test with a query on chaincode with peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'

Yes, you can do that using peer chaincode upgrade command.

peer chaincode upgrade -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n mycc -v 1.2 -c '{"Args":["init","a","100","b","200","c","300"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')"
