My IBM Type is 7870 which looks like this:
Raid 1 allows us Mirroring:
- Minimum 2 Disks.
- good performance ( there are not striping or parity).
- Good redundancy.
- Waste disk.
Ok, so let’s start,
In this specific type of server, we have to boot the raid configuration using “Ctrl + C” opposite to HP “F8”, The system which manages my raid configuration called “LSI Corp configuration”
The first step is to break the existing raid configuration:
select “Raid Properties ”
And I am deleting the existing one “Delete Array”
Confirm with Y
And now we need to create our raid so let’s carry on with “Raid Properties” selection:
There are three possibilities:
IM Volume – a situation that two disks both of them mirroring data, for example, type PELEGIT? It will write on the second disk as well
IME Volume – create a situation that 3 disks with “Hot Spare”
IS Volume – Striping, which means if you type “PELEGIT” so the first part “PELE” will write on the first disk and the rest “GIT” will write on the second disk,
I am selecting on – IM Volume
Press D which means “Overwrite existing data, create a new IM array All Data on All disks in the array will be Deleted!!”
Do it to the second disk as well. “Space”
After that, we have press on “C” which will create array for us
Out raid is ready!
