Checking the Cloud services version

This topic describes how to check the Cloud services versions of each node in a node class.

CLI commands do not work on a cluster if all nodes in a node class are not running the same version of the Cloud services. For example, you have three nodes (node1, node2, node3) in a node class (TCTNodeClass1). Assume that the Cloud services version of node1 is 1.1.1, of node2 is 1.1.1, and of node3 is 1.1.2. In this case, the CLI commands specific to 1.1.2 do not work in the TCTNodeClass1 node class.

To check the service version of all Transparent cloud tiering nodes in a cluster, issue the following command:
mmcloudgateway service version -N alltct
To check for service versions associated with Cloud services nodes, issue a command according to this syntax:
mmcloudgateway service version  [-N {Node[,Node...] | NodeFile | NodeClass}]
For example, to display the Cloud services version of the nodes, node1 and node2, issue the following command:
mmcloudgateway service version -N node1,node2
The system displays output similar to this:

 Node  Cloud node name                  TCT Type               TCT Version
---------------------------------------------------------------------------------
    8  node1                            Client                  1.1.5              
    9  node2                            Server                  1.1.5
To display the Cloud services version of each node in a node class, TCT, issue the following command: 
mmcloudgateway service version -N TCT
The system displays output similar to this:
Cluster minReleaseLevel:   5.0.1.0

 Node  Daemon node name                    TCT Type          TCT Version     Equivalent Product Version
------------------------------------------------------------------------------------------------
 1     jupiter-vm1192.pok.stglabs.ibm.com  Server            1.1.5           5.0.1.0
To display the client version of each node, issue the following command on the client node: 
mmcloudgateway service version
The system displays output similar to this:
Cluster minReleaseLevel: 5.0.1.0

Node Daemon node name TCT Type TCT Version Equivalent Product Version
------------------------------------------------------------------------------------------------
4 jupiter-vm649.pok.stglabs.ibm.com Client 1.1.5 5.0.1.0
To verify the client version of a particular node, issue the following command: 
mmcloudgateway service version -N jupiter-vm717
The system displays output similar to this:
Cluster minReleaseLevel: 5.0.1.0

Node Daemon node name TCT Type TCT Version Equivalent Product Version
------------------------------------------------------------------------------------------------
3 jupiter-vm717.pok.stglabs.ibm.com Client 1.1.5 5.0.1.0
To check for all nodes in a node class, issue the following command: 
mmcloudgateway service version -N tct
The system displays output similar to this:
Cluster minReleaseLevel: 5.0.1.0

Node Daemon node name TCT Type TCT Version Equivalent Product Version
------------------------------------------------------------------------------------------------
2 jupiter-vm482.pok.stglabs.ibm.com Server 1.1.5 5.0.1.0
1 jupiter-vm597.pok.stglabs.ibm.com Server 1.1.5 5.0.1.0
