Breaking mirror on Raid-1 + Raid-5 configuration

[Doris Soetanto]

Hello,

We are asked to do some recovery tests on a system with setup of: DISK 1 + 2 (Mirrored), 3 + 4 + 5 (RAID 5). Our objective is to revert/recovery the OS in the shortest time possible in case of patching/installation problem.

I am going to illustrate the steps below:
1. --- = RAID-1 / = RAID-5

2. Shutdown

3. -x- = Break mirror by pulling out

4. Patching/Installation = Big problem = Recovery/Revert

5. Shutdown

6. Pull out and insert in, turn on server

7. Shutdown

8. With inserted, insert , turn on server

9. Insert for rebuilding

Are the steps above correct? Am I missing any steps? I was told that step 6 is required (involving the RAID-5), but I myself not so sure, and hope to find the answer here. Any inputs are highly appreciated. Thank you in advance.

Sorry, just realized my post above is in the wrong section. The setup is for ProLiant DL server with Smart Array 5i/6i.
