Configuring Interactively
To configure interactively, do the following:
1. Create one or more drive groups
2. Create one or more logical RAID drives
3. Create a logical RAID drive of RAID level 0, 0 + 1, or 1
4. Define a spare drive
5. Specify caching policy
To configure interactively, you must do the following:
1. Create one or more drive groups
A drive group defines the drives that you want to work together as the available
space for the logical RAID drives that you will create.
2. Create a logical RAID drive
A logical RAID drive allows your system to see and respond to a drive group as a
single drive and defines how your system will store data in that space, based on
the RAID level selected.
3. Add a hot spare (optional)
A hot spare drive is a drive available in your subsystem for the controller to
automatically begin to use, in the event of a disk failure from a redundant logical
RAID drive, to store the data of the failed drive.
4. Initialize the logical RAID drives
Initialize a logical RAID drive before you use it to ensure consistent RAID parity
information.
5. Save your configuration to diskette
Your RAID subsystem stores the configuration information on flash
EEPROM/NVRAM on the RAID controller. In the event that your RAID
controller fails, you must restore your configuration from a backup copy on floppy
disk, or create a new configuration to access the data on your subsystem.
