I wonder if it's due to running newer firmware. I did update the cards to fw v.20.something before I moved to omnios. Is there a particular firmware version on the cards I should run to match OmniOS's drivers?

Google "LSI P20 firmware" for many tales of woe for many different OSes.
Be aware that getting the latest version of firmware from Avago might not be obvious...
the latest version is 20.00.04.00 for Windows.

But I've come into an issue where when I reboot any of them, I'm getting boot-archive service timeouts happening. I found a workaround of increasing the timeout value which brings me to the following. As you can see below in a dmesg output, it's taking the kernel about 8 seconds to detect each of the drives. They're connected via a couple SAS2008 based LSI cards.

Which means it takes between 12-24 minutes to boot those machines up.
