RAID 5 after EFI shell + HP UX

After lot of struggle we found which was said to us, to press ESC + 8 (number key) to go after selecting EFI shell while HP UX 11.31 OS installation.
this is actually HARDWARE RAID selection while installation of HP-UX operating system on RX2660 system. what i was doing, toggling between f8 key and ESC key. these were bringing me every time to HPUX>
after this we need to write exit and then we come to SHELL> or shell>

then RESET (reset as command in small letter) and then system reboots and again this cycle repeats.

now when after selecting EFI SHELL from boot screen, we did following.

"'Combination of ESC and 8 (number 8 key)worked, need to press them simultaneously. When asked after booting the server in EFI shell."" 

 Requirement is :- TO REMOVE OLD RAID 1+0 (HARDWARE RAID) AND RECONFIGURING RAID 5 AS HARDWARE RAID FOR ALL THE DISK AND MORE SPACE IN TOTAL OF 4 DISKS. 

first of all, we have to check old configuration by selecting view logical drive. it showed us RAID 1+0. after this we selected F3 , if it doesn't work then use combination of ESC and 3(number 3 key) simultaneously again. It will show a message like below. confirm the same using again ESC and 3 key.

Now it will say saving configuration ad bring back to the 3 option as in the first screen shots. we can check the same using view logical drive option. now select CREATE LOGICAL DRIVE. here we need to select all drive on or left side, we selected our 4 drives, in your case may be different. and on right side with arrow keys select RAID 5. and save the configuration with combination of keys suggested. save it check and again. and exit and reboot with new installation via DVD or via IGNITE. after installation, continue to use HP UX. my love. :) cheeerss!!!!!!!!!!!!!!
