Issue when I want to mark the disk as a flash disk

[corsafr]

Hello,

I have an issue when I want to mark my local disk as "flash disk" on the web client vCenter.

I have this message :

"Cannot mark disk naa.600605b01045fa60272c350379077495 as "Flash". "Unable to reconfigure the disk claim rules. The disk is in use."

For your information my ESXi is in 6.7.0 Update 3 (Build 14320388)

Thanks for your help

Hey @corsafr,

I presume you are not using this disk for anything right? Is this disk detected as USB?

[corsafr]

Disks are used for ESXi OS only.

They are local disk on the server.

In vCenter I don't see USB drive but only HDD SAS.

Hey @corsafr,

That is your issue then, you are trying to mark as Flash a disk that is being used by the ESXi OS. So in this case, what do you want to mark it as Flash?
