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.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string.

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_elastic san_volume group_create'.The syntax is: az elastic-san volume-group create --elastic-san
                                   --name
                                   --resource-group
                                   [--encryption {encryptionatrestwithcustomermanagedkey, encryptionatrestwithplatformkey}]
                                   [--encryption-properties]
                                   [--identity]
                                   [--network-acls]
                                   [--no-wait {0, 1, f, false, n, no, t, true, y, yes}]
                                   [--protocol-type {iscsi, none}]. The 1th example of the child command would be to use it to 'create a volume group with plaformmanagedkey and systemassignedidentity', the syntax is: az elastic-san volume-group create -e "san_name" -n "vg_name" -g "rg" --tags '{key1910:bbbb}' --encryption EncryptionAtRestWithPlatformKey --protocol-type Iscsi --network-acls '{virtual-network-rules:[{id:"subnet_id",action:Allow}]}' --identity '{type:SystemAssigned}'. The 2th example of the child command would be to use it to 'create a volume group with customermanagedkey and userassignedidentity', the syntax is: az elastic-san volume-group create -e "san_name" -n "vg_name" -g "rg" --encryption EncryptionAtRestWithCustomerManagedKey --protocol-type Iscsi --identity '{type:UserAssigned,user-assigned-identity:"uai_id"}' --encryption-properties '{key-vault-properties:{key-name:"key_name",key-vault-uri:"vault_uri"},identity:{user-assigned-identity:"uai_id"}}'.

It is used to the name of the volumegroup.. 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 '--encryption' is optional. type of encryption.. The parameter '--encryption-properties' is optional. encryption properties describing key vault and identity information  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--identity' is optional. the identity of the resource.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--network-acls' is optional. a collection of rules governing the accessibility from specific network locations.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--protocol-type' is optional. type of storage target..
