You can direct WebPAM to expand a logical drive beyond the maximum
expansion size. When the expansion is finished, WebPAM will show the logical
drive in the desired size. However, your operating system might show the logical
drive at the maximum expansion size (listed in the table above) and the rest of
the capacity as unformatted disk space.
At this point, you can:
• Format the disk space, which results in a second logical drive
• Create a new logical drive. See below
Create a New Logical Drive
To create a new logical drive:
1. Backup the data from the current logical drive.
2. Delete the current logical drive.
See page 100 (WebPAM PROe) or page 147 (CLU).
3. Create a new logical drive with the desired capacity.
See page 98 (WebPAM PROe) or page 146 (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
VTrak’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.
See “Physical Drive Media Patrol” on page 91.
