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_stack hci vm_disk_create'.The syntax is: az stack-hci-vm disk create --custom-location
                            --name
                            --resource-group
                            [--block-size-bytes]
                            [--disk-file-format]
                            [--dynamic {false, true}]
                            [--location]
                            [--logical-sector-bytes]
                            [--physical-sector-bytes]
                            [--polling-interval]
                            [--size-gb]
                            [--storage-path-id]
                            [--tags]. The 1th example of the child command would be to use it to 'putvirtualharddisk', the syntax is: az stack-hci-vm disk create --resource-group "test-rg" --custom-location "/subscriptions/a95612cb-f1fa-4daa-a4fd-272844fa512c/resourceGroups/dogfoodarc/providers/Microsoft.ExtendedLocation/customLocations/dogfood-location" --location "West US2" --size-gb 2 --name "test-vhd" --storage-path-id "/subscriptions/a95612cb-f1fa-4daa-a4fd-272844fa512c/resourceGroups/dogfoodarc/providers/Microsoft.AzureStackHCI/storagecontainers/test-storagepath". The parameter '--custom-location' is required. It is used to the id of the extended location.. The parameter '--name' is required. It is used to name of the virtual hard disk.. 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 '--block-size-bytes' is optional. block size.. The parameter '--disk-file-format' is optional. disk file format of the virtual hard disk - vhd or vhdx.. The parameter '--dynamic' is optional. boolean for enabling dynamic sizing on the virtual hard disk.. The parameter '--location -l' is optional. if location is not specified, the location of the resource group is used.. The parameter '--logical-sector-bytes' is optional. logical sector..
