The problem appears to be that the driver for the Perc H330 is failing 
to load.
Here is the relevant lines from dmesg.

[   39.229284] megaraid_sas 0000:02:00.0: Could not get controller info.

This is the backport buster kernel.

   # uname -r
   5.5.0-0.bpo.2-amd64

This is the kernel module is:

   # ls -l 
/lib/modules/5.5.0-0.bpo.2-amd64/kernel/drivers/scsi/megaraid/megaraid_sas.ko
   -rw-r--r-- 1 root root 315652 Apr 23 15:15  
/lib/modules/5.5.0-0.bpo.2-amd64/kernel/drivers/scsi/megaraid/megaraid_sas.ko

So, then I checked to see if there were any kernel updates that could be 
applied and
indeed there were.

   # uname -r
   5.6.0-0.bpo.2-amd64

But the problem persists:

[   40.048619] megaraid_sas 0000:02:00.0: Could not get controller info.

Not sure what to try next.  Fall back to the stock buster kernel maybe.  
Suggestions
welcomed.
