The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'.

You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_managed cassandra_datacenter_update'.The syntax is: az managed-cassandra datacenter update --cluster-name

                                       [--node-count]. The 1th example of the child command would be to use it to 'scale the number of nodes in a datacenter  this is a scale up operation assuming that the create datacenter was done with 3 nodes  each datacenter should atleast have 3 nodes', the syntax is: az managed-cassandra datacenter update --resource-group MyResourceGroup --cluster-name MyCluster --data-center-name MyDataCenter --node-count 6. The 2th example of the child command would be to use it to 'scale the number of nodes in a datacenter  this is a scale down operation assuming that the create datacenter was done with 3 nodes  followed by a scale up to 6 nodes  each datacenter should atleast have 3 nodes', the syntax is: az managed-cassandra datacenter update --resource-group MyResourceGroup --cluster-name MyCluster --data-center-name MyDataCenter --node-count 4. The parameter '--cluster-name -c' is required. It is used to cluster name.. The parameter '--data-center-name -d' is required. It is used to datacenter name.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--backup-storage-customer-key-uri -p' is optional. indicates the key uri of the customer key to use for encryption of the backup storage account.. The parameter '--base64-encoded-cassandra-yaml-fragment -b' is optional. this is a base64 encoded yaml file that is a subset of cassandra.yaml.  supported fields will be honored and others will be ignored.. The parameter '--ldap-search-base-dn' is optional. distinguished name of the object to start the recursive search of users from.. The parameter '--ldap-search-filter' is optional. template to use for searching. defaults to (cn=%s) where %s will be replaced by the username used to login. while using this parameter from windows powershell (not windows commandprompt or linux) there is a known issue with escaping special characters, so pass as """(cn=%s)""" instead.. The parameter '--ldap-server-certs' is optional. ldap server certificate. it should have subject alternative name(san) dns name entry matching the hostname of the ldap server.. The parameter '--ldap-server-hostname' is optional. hostname of the ldap server.. The parameter '--ldap-server-port' is optional. port of the ldap server. defaults to 636.. The parameter '--ldap-service-user-dn' is optional. distinguished name of the look up user account, who can look up user details on authentication.. The parameter '--ldap-svc-user-pwd' is optional. password of the look up user.. The parameter '--managed-disk-customer-key-uri -k' is optional. key uri to use for encryption of managed disks. ensure the system assigned identity of the cluster has been assigned appropriate permissions(key get/wrap/unwrap permissions) on the key.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--node-count -n' is optional. the number of cassandra virtual machines in this data center. the minimum value is 3..
