Oh
Any linux command to do this instead of unplugging all of them and finding a HBA controler card

Thats the problem though isnt it; "linux" wont see the drive until you do.

I find this and it's probably the reason why the drive doesn't worki

As I mentioned before, so much drama with PERC controllers in HBA-mode. Just swap them out for a Dell HBA330 true IT-mode storage controller. Your future self will thank you. They are cheap to get.

I got a 330 but don't know if it's a HBA .. should i flash it to it-mode ?

Ok i ordered this one finally from Ebay
Dell PERC HBA330 mini mono 12G SAS Storage Controller SSD JBOD pass-through

I think i must do the 512b trick to be able to use the drives ?

Don't forgot to flash the HBA330 to the latest firmware from dell.com/support

I compile this utility to format SAS drives to 512-bytes or do a low-level format https://github.com/ahouston/setblocksize

You'll need to install the sg3_utils package.

While doing that, might as install sdparm package and enable the write cache on the SAS drive as root running the following command:

sdparm -s WCE=1 -S /dev/sd[x]

Where 'x' is the drive letter.
