Hi Eric,
<div><br>
</div>
<div>Thanks for the reply, it is actually the JBOD SKU so the firmware is IT not IR.</div>
<div><br>
</div>
<div>I've actually managed to solve the issue now by disabling the "Onboard SAS option ROM" and "Interrupt 19 Capture" in the BIOS.<br>

<br>
</div>
</div>
I'm not sure which one actually solved the issue or if it was a combination of the two.</div>

I'm having a strange issue with OmniOS.<br>
<br>
I have a Supermicro 36 Bay Chassis with this motherboard:<br>
<br>
<a href="http://www.supermicro.co.uk/products/motherboard/Xeon/C600/X9DRD-7LN4F.cfm">http://www.supermicro.co.uk/products/motherboard/Xeon/C600/X9DRD-7LN4F.cfm</a><br>
<br>
With more than 34 drives the system fails to boot, all drives are seen by<br>
the LSI utility at POST and the POST completes successfully when OmniOS<br>
tries to boot I just get a black screen with a flashing cursor.<br>

<br>
This board's built-in SAS HBA comes with IR firmware, correct? It is<br>
not the "-JBOD" SKU?<br>
<br>
How have you set up the disks behind this controller? Are they<br>
individual RAID-0's or something else?<br>
<br>
Could you provide the PCI ID that your controller appears as? You can<br>
get this via `prtconf -d` or by installing the pciutils package and<br>
running /usr/sbin/lspci.<br>
<br>
Thanks,<br>
Eric<br>
