Correct disk/boot policies for VMware with C220 M5 + MSTOR-M2 + SAS-M5??

I've trailing some C220 M5 servers in my UCS Mini (with B200 M4s) home lab and just wanted to clarify the right disk and boot policy settings for this setup.

 

The servers have a UCS-MSTOR-M2 module with 240GB SSD and also a UCSC-SAS-M5 controller with multiple SAS SSDs.

 

I'm looking to run VMware ESXi 7.0 U2 and to boot from the single 240GB M2 drive, and use the SAS SSDs for a VMware vSAN datastore.

 

My Boot Policy is:

UEFI, boot Security enabled, and Embedded Local Disk with primary and slot 1 selected

 

My BIOS Policy has:

P-SATA mode set to AHCI

 

My Storage Policy has:

Auto Config Mode = Unspecified

Controller Definition set to enable protect configuration and RAID level set to "No RAID"

 

Local Disk Configuration Policy = Nothing configured, so I have one for this use case?

 

During the POST I can see a "M.2 SWRAID configuration is not detected. Switching to AHCI mode. warning

 

In the BIOS, under advanced, then LOM and PCIe Slots Configuration:

pSATA SATA OpROM = LSI SW RAID

M.2 SATA OpROM = AHCI

 

In UCS manager for this server under inventory, storage, I can see:

Storage Controller PCH 4 = AHCI mode

Storage Controller SAS 1

Storage Controller SATA 3 = SWRAID mode

 

According to this article https://www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-b-series-blade-servers/213757-installing-operating-systems-vmware-wi.html you simply need to create a controller definition with no-raid, and enable the p-sata to ahci, and that should take care of it.

 

Is anyone able to help explain why after doing the above I'm still seeing the p-SATA mode set to SWRAID?

 

Thanks
