I’ve a 64G mSATA adapter from http://shop.rockstor.com/collections/diy-accessories. Had it up and running in no time at all on a Dell 755 workstation and a pair of 1TB SATA drives. Good stuff.
But, came by a Dell PowerEdge 2950 (6 1TB drives on a RAID controller at RAID 6). Booting the Rockstor install from a DVD (wouldn’t boot from the USB I used on the 755), I was able to get a new install on to the mSATA drive - but no matter how I fiddle and tweak the BIOS, I’ve not been able to get the thing to boot. It’s hooking into the PE BIOS - I see the adapter’s splash in POST - but it never tries to boot. PE BIOS reports ‘no boot device’ and does the ‘F1 retry or F2 for setup’ dance.
If I install Rockstor or CentOS to the RAID itself - no problems, it all boots and runs just fine - but I’d rather use this mSATA for the OS.
Pretty sure I’ve gotta do some kind of magic to get the mSATA ‘visible’ as a boot device. And, I’ve run out of options and convolutions in the PE BIOS setup.
Any suggestions or ideas? Sorry, not alter for sacrifices - but may be tempted.
