3.11  Creating a New RAID or Reconfiguring an Exist-

ing RAID

You can configure RAID Sets and Volume Sets using 

Quick Create

 or 

RAID

Set Functions/Volume Set Functions

 configuration method. Each configu-

ration method requires a different level of user input. The general flow of op-
erations for RAID Set and Volume Set configuration is:

Step

Action

1

Designate hot spares/pass-through (optional).

2

Choose a configuration method.

3

Create RAID Set using the available physical drives.

4

Define Volume Set using the space in the RAID Set.

5

   Initialize the Volume Set and use Volume Set in the HOST OS.
