At this point, you have the choice of:
•
Format the unpartitioned/unformatted capacity as a second logical drive
•
Delete the existing disk array and create a new one in the desired size
Delete and Recreate
If you require a logical drive larger than the maximum expansion size:
1. Backup the data from the current logical drive.
2. Delete the current logical drive.
See page 158 (ASUS Storage Management) or page 235 (CLU).
3. Create a new logical drive with the desired capacity.
See page 156 (ASUS Storage Management) or page 234 (CLU).
4. Restore the data to the new logical drive.
Media Patrol
Media Patrol is a routine maintenance procedure that checks the magnetic media
on each disk drive. Media Patrol checks all physical drives assigned to disk
arrays. Media Patrol does not check unconfigured drives.
Media Patrol will also check spare drives, if those drives have Media Patrol
enabled. Media Patrol for spare drives is enabled by default. You can disable it in
ASUS Storage
’s Command Line Interface (CLI).
Unlike Synchronization and Redundancy Check, Media Patrol is concerned with
the condition of the media itself, not the data recorded on the media. If Media
Patrol encounters a critical error, it triggers PDM if PDM is enabled.
You can run Media Patrol from the subsystem. See
―Running Media Patrol‖ on
page 71 (ASUS Storage Management) or page 209 (CLU).
You can also run Media Patrol on a disk array.
See ―Running Media Patrol on a
Disk Arra
y‖ on page 160 (ASUS Storage Management only).
