CHAPTER
6 Changing the Volume Setup or
Creating Logical Volumes
The main steps involved in switching from one configuration to another
or creating logical volumes include:
Step 1 Selecting the applicable configuration.
Step 2 Creating the desired number of logical volumes, and setting their size.
Using the Default Volume Setup
The REO Appliance uses a default volume configuration of RAID 5 with
logical volumes. To use this configuration, you must create the logical
volumes.
X To use the default configuration and create logical volumes, proceed to
Creating Logical Volumes on page 71.
Changing the Volume Configuration
You can use the Volume Setup feature in the console to select a different
RAID configuration or to select the JBOD configuration.
Important: Be aware that the process of changing the volume
configuration takes time for the RAID 5 configurations while the
arrays are initialized. After you select the new configuration and the
initialization process begins, you can use the REO Appliance, but
performance will be impacted. Overland Storage strongly recommends
that you wait until the Status on the Physical Volume Management
page is OK (not INITIALIZING) before using a volume. (Switching to
a RAID 0 or JBOD configuration usually requires less than 10
minutes.)
