Raid 0 and Recovery HD

Hi all,

I have set up an Raid 0 with two SSD's and installed Sierra 10.12.6 on a Imac 27" mid 2011.

When I power up with cmd+R I get a world ball and takes some time to start. When I open Utilities - terminal, and try to use csrutil, the command is not found.

If I boot normally and make a diskutil list, I don't have the "Recovery HD", does anyone know how to be able to install it in order to be able to make a "csrutil disable"?

Thank you!
 
If you need to make a "csrutil disable" in the Terminal, hold Alt + Cmd + r on boot to start an Internet Recovery.

This will load a "Recovery partition" in RAM.
From there you can access a Terminal (menu bar / Utilities).

Thank you Bruno09, It worked perfectly!!
 
Wow... I have been upset about the issue of them locking us OUT of using arrays with a recovery partition... never saw nor heard any explanation WHY they "don't allow it." Gotta try this method...
 
Gave it my best shot... this "method" does NOT work. I even preceeded it by clearing P-RAM and setting startup drive and video driver. On the bong, held down cmd-option-R. System simply booted into my normal start up volume (yeah, I did not let up until I saw the Finder load). As the advice was to someone who did not have a recovery partition, assumed this key sequence fetches what is needed from the mothership. I am already running the last rev of Sierra.

So I dug a bit further... seems I DO have a recovery partition... it must have been made when I configured bootcamp on a single drive, I started that process with a clean OS install, then made the bootcamp partition. Thing is, the Recovery partition is 10.9.4. That partition was repurposed to be a clone of my normal startup array. 3 questions:

Can I run csrutil disable from a 10.9.4 Recovery partition?

Why did cmd-opt-R not do as suggested earlier?

If I wipe my clone partition and fresh install High Sierra, will it create a 10.13 Recovery partion (fwiw, this is a single drive in bay 1 of my Mac Pro)? Even with Bootcamp still on a separate partition? I would still have the option to recreate the clone there...
 
Rats... so all the other 2010 machines EXCEPT the tower, grrrr. BUT I do thank you for the links... gotta say I USED TO seriously tinker with the hardware and software (my favorite app for a LONG time was ResEdit), but these days I just want it to sit there and work!

Could you possibly answer the other 2 questions I posed?
