Changing RAID Levels
RAID levels can be changed using a drive in the Ready state in one of two ways:
•
From the Logical Drv Menu of the HP NetRAID Assistant
1. Select Logical View.
2. Highlight the logical drive you want to change from the Logical Devices box on the
right side of the screen.
3. Select Logical Drv, Change Status, RAID Level. The Change RAID Level dialogue
box opens.
4. Select your new RAID Level from the levels available for the new logical drive
configuration.
5. Select Apply. The Reconstruction Progress of the logical drive rebuild is displayed in
a message box and in the Logical Devices box.
•
By drag and drop, moving the icon of a physical drive in the Ready state from the Physical
Devices box into a logical drive icon in the Logical Devices box. To change RAID levels of
logical drives by using the icons, at least one physical drive must be in the Ready state.
1. Drag the icon of a physical drive in the Ready state from the Physical Devices box into a
logical drive in the Logical Devices box.
2. A dialogue box will prompt you to select a new RAID level from those available in the
pulldown menu.
3. Click Apply. The logical drive you are changing will begin to Reconstruct.
NOTE Once started, reconstruction cannot be stopped.
Re-configuring Arrays and Logical Drives
If you want to re-configure a configuration in which all physical drives are Online or hot spares, you
must clear the configuration and create a new configuration, preferably with the Custom
configuration.
You may add Ready physical drives to an existing configuration by using the RAID Configuration
Wizard.
Changing Logical Drive Parameters
To change logical drive parameters via the HP NetRAID Assistant Logical Drv Menu options, refer
to the previous section logical drives Menu Options.
Taking a Drive Offline/Online
A NetServer physical drive can be taken offline or put online in one of two ways:
•
Manually, by removing or inserting the disk drive by hand from a NetServer hot swap bay.
•
As a menu selection, by highlighting the drive with the mouse pointer and selecting Physical
Drv Menu, Change Status, Make Offline or Make Online. (Only a Failed drive can go online
in this way. To put a Ready drive online, you must use the Configuration options.)
Making a drive Offline will put the drive into a Failed state.
