UCSD Workflow-Windows VM Disk Create (Partition, Format and Assign Drive Letter) (VIX to VBS)

midupont · ‎06-18-2015

Task Name	VM Details
Description	Retrieve datastore for current VM and create a disk on that datastore Create and execute a temporary VB script to partition and format the drive
Prerequisites	Tested on 5.3 vCenter (VIX script execution does not work on any other hypervisor) Will only work on a Windows VM. Linux VMs need to be handled completely differently.
Category	Workflow
Components	vSphere 5.x
User Inputs	Disk Size of new disk Drive Letter for new disk Drive Label of new disk Username of administrative user of the VM Password of the administrative user of the VM

Instructions for Regular Workflow Use:

Download the attached .ZIP file below to your computer. *Remember the location of the saved file on your computer.
Unzip the file on your computer. Should end up with a .WFD file.
Log in to UCS Director as a user that has "system-admin" privileges.
Navigate to "Policies-->Orchestration" and click on "Import".
Click "Browse" and navigate to the location on your computer where the .WFD file resides. Choose the .WFD file and click "Open".
Click "Upload" and then "OK" once the file upload is completed. Then click "Next".
Click the "Select" button next to "Import Workflows". Click the "Check All" button to check all checkboxes and then the "Select" button.
Click "Submit".
A new folder should appear in "Policies-->Orchestration" that contains the imported workflow. You will now need to update the included tasks with information about the specific environment.

This example uses a VBS script. To see a DOS only version that accomplishes a similar result see Windows VM Disk Create (Partition, Format and Assign Drive Letter)(VIX to DOS)

Results after execution:

Note:

If VIX has a UCSD variable all \\ turn into \\\\, this is seen is task 4 of the workflow.

The following 3 symbols can be passed to a Windows echo command ONLY when on the FIRST line of the VIX script task: & > <

In all cases the symbol needs to be passed with \^ in front.

The \ being the VIX escape character and the ^ being the DOS escape character. This can be seen on the first line of steps 5 and 6.

Before execution:

After execution:

The included custom tasks:

1) Create VM Disk to force disk size selector and force the "system" disk type selection (Step 2 of the attached workflow)

2) Select the first datastore of the target VM where the new disk is to be provisioned (Step 1 of the attached workflow)

Caveats

If there is already a raw disk on the VM then it is possible the script will partition and format the wrong disk. Since disks are added in increasing order (i.e. index number) it is very likely that the new disk will have a higher number than the older disk so the new disk will be the one that gets partitioned and formatted. The only way the wrong raw disk will be partitioned and formatted is if a previous disk was deleted from the system with a higher index raw disk and then a new disk gets created which would be given a lower index number than the previously created raw disk.
