LSI9211-8i MegaCli64

I'm trying to get MegaCli64 to work with my RAID controller, which is an LSI9211-8i. Unfortunately, any query returns blank:

[root@hostname MegaCli]# ./MegaCli64 -CfgDsply -aAll
                                     

Exit Code: 0x00

This is on a SuperMicro box. Is this controller compatible with MegaCli?

Got it! Had to use sas2ircu.

SAS2IRCU, available from the following link:
Supermicro SuperBlades, uGPU, AI System, Multi-Node Servers_lib/FAQ_9633_SAS2IRCU_Phase_5.0-5.00.00.00.zip

User guide is here:
Broadcom Inc. | Connecting Everything_SATA_6G_P12/SAS2IRCU_User_Guide.pdf

Which version of megacli are u using.
Can u download the latest megacli from lsi site.
Could it be
Megacli64 -CfgDsply a0

Iam just trying to remember off of my head. I can try in my 9261-8i tomorrow.
Let me know.

I actually needed to use sas2ircu instead of MegaCli!
