Change online RAID level 6 to 5 on D2600 and smart array P441

Hello.

Firstly, I'm a french guy and my english is very bad, sorry if I made mistakes.

I would like to convert a LogicalDrive in a D2600 from RAID level 6 to RAID level 5.

My first question : Is it possible ?

My server is a "HP Proliant DL380 Gen9" with a RAID Card P441 and an additional storage HP2600.

The Operating system is VMware vSphere 6 Essentials,  installed with the custom ISO HPE.

All the storage on the D2600 is dedicated for one volume presented to one VM (Windows server 2012 R2).

We have got a pb on this storage for a few days. All free space are used by temporary vm disk and the

VM is unavailable.

 

I want increase the free space available on the D2600 storage converting from RAID level 6 to RAID level 5, if it's possible.
