A colleague of mine became very curious about my Promise Pegasus2 R4 and found out on his own that it was possible to release it´s hard drives while the device was still on. This caused the disks to go into Offline Mode.
To change the four hard drives in Pegasus2 back to Online Mode again, I could not use the latest version of Promise Utilities that I had installed on the Mac. This the latest version of Promise Utilities, lacked commad line tools(CLI-features) which I found out was needed to get the drives Online again. When I typed: promiseutil in the Macs terminal application, it answered with "Command not found". I had to go to: https://www.promise.com/Support/downloadcenter and look for an installer for an older version of Promise Utilities that also contained the Promise CLI tools. I went for a version 4 because I had seen one used it with CLI commands on one of kb.promise.com´s pages. When I installed this older version of Promise Utilities, the promiseutil showed up at ones when I typed "promiseutil" i the Macs Terminal application:

Now to get all four hard drives in the Pegasus2 R4 raid Online again, I had to type the followig line, one time for each drive and change the number to 2, 3, 4 and press Enter(return) each time to confirm the action to the Pegasus2 R4:
phydrv –a online –p 1
A fast way to do this is to type the line over ones, press Enter(return) and then press the Up-arrow on the keyboard(to repeat last command), change the number and press Enter(return) and repeat this.
I believe that if you have more that four drives i the Pegasus2 R4 raid, the process will be the same.
