There is a command group 'az_scvmm_vm_disk'. This group of commands could 'managing the disks of arc for scvmm virtual machine'. 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_scvmm_vm_disk_add'.The syntax is: az scvmm vm disk add --bus
                     --disk-size
                     --name
                     --resource-group
                     --vm-name
                     [--bus-type {ide, scsi}]
                     [--lun]
                     [--no-wait]
                     [--qos-id]
                     [--qos-name]
                     [--vhd-type {dynamic, static}]. The 1th example of the child command would be to use it to 'create a virtual disk with size 100 gb to a virtual machine and attach it to bus 1 lun 10 scsi controller', the syntax is: az scvmm vm disk add --subscription contoso-sub --resource-group contoso-rg --vm-name contoso-vm --name disk_2 --bus 1 --lun 10 --bus-type SCSI --disk-size 100. The parameter '--bus' is required. It is used to bus number for the disk.. The parameter '--disk-size' is required. It is used to size of the disk in gb.. The parameter '--name -n' is required. It is used to name of the 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 '--vm-name' is required. It is used to name of the virtual machine.. The parameter '--bus-type' is optional. bus type of the disk.. The parameter '--lun' is optional. lun number for the disk.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--qos-id' is optional. uuid of the storage qos policy to be applied on the disk.. The parameter '--qos-name' is optional. name of the storage qos policy to be applied on the disk.. The parameter '--vhd-type' is optional. vhd type of the disk..
