pre 3.1 Volume Templates - any way to change the Prov type ?

[martin2176]

I have dozens of pre 3.1 Volume templates, which at that time did not suppport Thin DD.

Now with 3.1, Thin DD is supported. Is there a way to change the provisioning type of a pre 3.1 Vol template from Thin to ThinDD.

A pre 3.1 Vol template, Edit does not give an option to change the "provisioning" to "Thin DD"

I dont want to delete and recreate these templates in 3.1 just to change the provisioning type.

This is a defect in OneView 3.1.  A fix for this is planned for the upcoming 3.10.08 patch.

OneView 3.0 volume templates upgraded to 3.1 are not getting the "Thin Deduplication" option added to them, so don't show up when editing/using the upgraded volume template.  Volume templates created in OneView 3.1 are fine.

A simple fix is to delete and recreate your affected volume templates in OneView 3.1.  This is what you said you didn't want to do, but i wanted to document it as an option.

You can repair your upgraded volume templates by performing the following REST operations.  This assumes you are familiar with using the OneView REST api.  If so, continue.  If not, then you can wait for the patch or use the recreate option above.

To repair an existing OneView 3.1 volume template, perform the following using the REST client of your choice:

1. Perform a GET on the URI of the volume template to repair.  The URI can be seen in the OneView UI when viewing the volume template (ex. GET <host>/rest/storage-volume-templates/108a1864-4812-40f9-a875-a7d9004a4ede )
2. In the reply, find the property definition below and add "Thin Deduplication" to the "enum" list as shown underlined below:

{

...

"properties": {

"provisioningType": {

"enum":[ "Thin", "Full", "Thin Deduplication"]

...

}

3. Perform a PUT of the modified reply above back to the volume template (ex. PUT <host>/rest/storage-volume-templates/108a1864-4812-40f9-a875-a7d9004a4ede )

After repair, you should be able to edit the volume template in the OneView UI, selecting among the three provisioning type values (Full, Thin, Thin Deduplication), and create volumes using the volume template.

the REST API method is good enough until a formal fix comes via the GUI.  Thanks for the solution
