5.3.6 Clearing a Configuration
A Warning message dialog appears when you select Clear Configuration from the Configuration Management
menu.
As stated in the warning text, this command deletes all virtual drives and hot spare drives attached to the controller.
CAUTION All data on the virtual drives is erased. If you want to keep this data, be
sure you back it up before using this command.
To complete the command, follow these steps:
1. Highlight the brackets next to Confirm and press the spacebar.
An X appears in the brackets.
2. Highlight Ye s and press Enter.
A success message appears.
3. Highlight OK and press Enter.
The HII Utility clears the configuration and returns you to the Configuration Management menu.
5.3.7 Make Unconfigured Good and Make JBOD
When you power down a controller and insert a new physical drive, if the inserted drive does not contain valid DDF
metadata, the drive status is listed as JBOD (Just a Bunch of Drives) when you power the system again.When you
power down a controller and insert a new physical drive, if the drive contains valid DDF metadata, its drive state is
Unconfigured Good. A new drive in the JBOD drive state is exposed to the host operating system as a stand-alone
drive. You cannot use JBOD drives to create a RAID configuration, because they do not have valid DDF records. First,
the drives must be converted to Unconfigured Good.
If the controller supports JBOD drives, the Configuration Management menu of the HII utility includes options for
converting JBOD drives to Unconfigured Good, or vice versa.
