2. Delete the container pair set by issuing a command similar to this:

   mmcloudgateway containerpairset delete --cloud-nodeclass cloud1 --container-pair-set-name vm206

   For more information, see Binding your file system or fileset to the Cloud service by creating a container pair set.
3. Delete the cloud services by issuing a command similar to this:

   mmcloudgateway cloudservice delete --cloud-nodeclass cloud --cloud-service-name newServ

   For more information, see Creating cloud services.
4. Delete the CSAP by issuing a command similar to this:

   mmcloudgateway cloudStorageAccessPoint delete --cloud-nodeclass cloud --cloud-storage-access-point-name  csap1

   For more information, see Defining cloud storage access points (CSAP).
5. Delete the cloud storage account by issuing a command similar to this:

   mmcloudgateway account delete --cloud-nodeclass cloud --account-name new

   For more information, see Managing a cloud storage account.
6. Stop the cloud services on all nodes by issuing a command similar to this:

   mmcloudgateway service stop -N cloud1

   For more information, see Stopping cloud services software.
7. Disable cloud services nodes on the node group by issuing a command similar to this:

   mmchnode --cloud-gateway-disable -N vm1,vm2 --cloud-gateway-nodeclass cloud1

   For more information, see Designating the cloud services nodes.
8. Delete the node class if required. For more information, see the mmdelnodeclass command command.
9. Uninstall the cloud services RPMs (both server and client) from all the nodes by issuing the following command:

   • rpm -e gpfs.tct.server-x-x.x.x86_64

   • rpm -e gpfs.tct.client-x.x.x.x86_64.rpm
