You cant just delete the raid and reinstall.
You have to configure some sort of storage setup on the raid card.
Otherwise the raid card doesn't present any drives to the OS.

The RAID card OVH uses doesn't support passthrough or JBOD so you have to configure single disk raid0.

Here is my setup the device numbers may be different for you.

# ovh disable hardware raid
MegaCli64 -CfgLdDel -LAll -aALL
MegaCli64 -cfgClr -aAll
MegaCli64 -AdpPR -Dsbl -aALL

# create devices
MegaCli64 -CfgLdAdd -r0 [6:0] -a0
MegaCli64 -CfgLdAdd -r0 [6:1] -a0

# only use this for raid 0
MegaCli64 -adpsetprop MaintainPdFailHistoryEnbl 0 -a0

# caching for better performance
MegaCli64 -LDSetProp -Cached -LAll -aAll
MegaCli64 -LDSetProp EnDskCache -LAll -aAll
MegaCli64 -LDSetProp WB -LALL -aALL

# Ensure it is bootable
MegaCli64 -AdpBootDrive -Set -L0 -a0

After doing this verify that you have the device /dev/sda before doing reinstall on ovh manager.

Hello Guys,
I have recently purchased MG SSD box, it came out with megraid 1, i have switched to raid0 and performance wasn't that good so i want to disable hw raid at all and just install the box in software raid
however when i deleted the raid via rescue mode when i try to reinstall the box via manager i get the following error : "Error during partitions reset: Unable to find HD interface "

Anyone knows how to fix this ? or any other ideas how to optimize ssd disks via megaraid ? (getting only 200-300mb/s via dd while sata2 with software raid gives more)

Thanks a lot,
Dima.
