Exploring VSAN APIs Part 7 - VSAN Datastore Folder Management

In addition to storing your Virtual Machines, you may also want to use the VSAN Datastore to store your operating system ISOs in case you do not have an external repository and would like to keep everything local. If you use the vSphere Web Client to perform this operation, you will notice that you will need to first create a top-level directory before you can upload an ISO or a file to the VSAN Datastore.

The reason for this is that the VSAN Datastore does not support files in the top level directory, so you will have to first create a top-level directory and then upload the files under that directory. To create these top-level directories, a new DatastoreNameSpaceManager is introduced in the vSphere 5.5 API which manages the creation and deletion of these directories. Once these top-level directories exists, you can then use the regular fileManager API to manage your files and sub-directories within the VSAN Datastore. To demonstrate the creation of a top-level directory and sub-directory in a VSAN Datastore, I have created a sample vSphere SDK for Perl script called vsanDatstoreFolderMgmt.pl

Disclaimer: These scripts are provided for informational and educational purposes only. It should be thoroughly tested before attempting to use in a production environment.

In this example, I will create a top-level directory in the VSAN Datastore called ISO and then a sub-directory under that called Linux by running the following command:

./vsanDatstoreFolderMgmt.pl --server vcenter55-1.primp-industries.com --username root --vsan-datastore vsanDatastore --root-folder ISO --sub-folder Linux

The script will first call the DatastoreNameSpaceManager CreateDirectory() API method which will then create the top-level directory and then using the fileManager's MakeDirectory() API method to create the sub-directory. If we take a look at our VSAN Datastore using the vSphere Web Client, we can see that our new top-level directory has been created along with our sub-directory.

For deleting sub-directories and the top-level directories, there is the DeleteDatastoreFile_Task() and DeleteDirectory() API method respectively.
