SROMBSASMR BIOS RAID error on cold boot (i.e., after power has been removed for 30+sec):
Number of devices exceeded the maximum limit of devices per quad
Please remove the extra drives and reboot system to avoid losing data
System has halted due to unsupported configuration
With the system thusly halted, I can then hit the Reset and the system will boot correctly, with the SROMBSASMR bios correctly recognizing the physical drives and logical units.
But every cold start causes the RAID bios error to recur.
I have wiped the configuration and re-created, but the same error recurs.
AXX6DRV3GEXP 6-bay HS cage
SROMBSASMR add-on RAID controller (FW ver: 1.40.62-0665)
(6) Seagate ST31000340NS 1TB drives (set for 3GB/s SATA)
Logical unit config:
2x drives in a RAID1
4x drives in a RAID 10 (comprised of two spans of two drives each)
The problem is now resolved.
It turns out that a replacement backplane for the AXX6DRV3GEXP had an older FW version (2.02, I believe). Upgrading the AXX6DRV3GEXP FW to 2.12 has resolved the issue.
