There is a command group 'az_hpc cache_nfs storage target'. This group of commands could 'commands to create hpc cache nfs storage target'. 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. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. 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_hpc cache_nfs storage target_add'.The syntax is: az hpc-cache nfs-storage-target add --cache-name
                                    --junction
                                    --name
                                    --nfs3-target
                                    --nfs3-usage-model
                                    --resource-group. The 1th example of the child command would be to use it to 'storagetargets_createorupdate', the syntax is: az hpc-cache nfs-storage-target add --resource-group "scgroup" --cache-name "sc1" --name "st1" --nfs3-target 10.7.0.24 --nfs3-usage-model WRITE_AROUND --junction namespace-path="/nt2" nfs-export="/export/a" target-path="/1" --junction namespace-path="/nt3" nfs-export="/export/b". The parameter '--cache-name' is required. It is used to name of cache.. The parameter '--junction' is required. It is used to list of cache namespace junctions to target for namespace associations.the sub parameters contains: (1) --namespace-path: namespace path on a cache for a storage target (2) --nfs-export: nfs export where targetpath exists (3) --target-path(optional): path in storage target to which namespacepath points.. The parameter '--name' is required. It is used to name of the storage target.. The parameter '--nfs3-target' is required. It is used to ip address or host name of an nfsv3 host (e.g., 10.0.44.44).. The parameter '--nfs3-usage-model' is required. It is used to identify the primary usage model to be used for this storage target. you can use command `az hpc-cache usage-model list` to see the names of usage models. for more details about usage models, please refer to https://docs.microsoft.com/azure/hpc-cache/hpc-cache-add-storage?tabs=azure-cli#choose-a-usage-model.. 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>`..
