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.
