I striped a couple of 250 SSDs with Disk Utility and cloned my sys HDD onto them. I was going to start with the pointers but thought I would give it a try without first. It worked, and I am now writing this on the machine. Here's how ...
I kept the sys HDD in the mix as a backup. When the TonyMac splash-screen comes up it shows the USBEFI, SSD, SSD2 and sys HDD.
To startup on the RAID click either of the SSDs. It will say - Can't find kernel...... press any key. Press any key and you come back to the splash-screen, then I click on sys HDD and it starts up in the RAID. Clicking the SSD seems to give it the path.
If I want to startup on the sys HDD I just click on that in the first splash-screen.
Well, it's working for me, and everything seems good so far. Thought you might like to try before going into the terminal.
