   For details about cluster status during creation, see the description of the status parameters in Table 1.

   It takes some time to create a cluster. The initial status of the cluster is Starting. The cluster status will change to Running if the cluster is successfully created.

   On the MRS management console, a maximum of 10 clusters can be created concurrently, and a maximum of 100 clusters can be managed.
