Choosing The Configuration Method - LSI SCSI 320-0 Configuration

Choosing the Configuration Method

Automatic Configuration In Automatic Configuration, the MegaRAID controller examines the
physical drives connected to it and automatically configures them into arrays
and logical drives.
If logical drives have already been configured when you select Auto
Configuration, the configuration information is not disturbed. See page 68 for
additional information.
Easy Configuration In Easy Configuration, each physical array you create is associated with
exactly one logical drive, and you can modify the following parameters:
•
RAID level
•
stripe size
•
cache write policy
•
read policy
•
I/O policy
If logical drives have already been configured when you select Easy
Configuration, the configuration information is not disturbed.
See page 69 for instructions on Easy Configuration.
New Configuration In New Configuration, you can modify the following logical drive
parameters:
• RAID level
• stripe size
•
cache write policy
•
read policy
•
I/O policy
•
logical drive size
•
spanning of arrays
If you select New Configuration, the existing configuration information on the
selected controller is destroyed when the new configuration is saved. See page
73 for instructions on New Configuration.
View/Add Configuration View/Add Configuration allows you to control the same logical drive
parameters as New Configuration without disturbing the existing configuration
information. See page 76 for additional information.
Reserved Disk Space during Configuration Up to 20.6 MB of disk space is reserved when a
hard disk drive is being configured.
