Reclaiming Space on Disk Extension Media
Over time, the media used for storage policies (known as Disk Extension media) develops wasted space as
it is used in the Pathlight VX. Wasted space is a normal by-product of using Disk Extension media in the
system. This space will be automatically reclaimed when virtual media are recycled and as backups expire.
Use this procedure to reclaim wasted space on Disk Extension media.
1 From the menu bar, select Operations→ Media Management→ Physical→ Disk Extension.
The Operations - Manage Disk Extension Media screen appears.
2 Select Space Reclamation and click Next.
The Disk Extension Media - Space Reclamation screen appears and lists all formatted Disk
Extension media in the Pathlight VX. For each media, the following information is provided: Barcode,
Media Type, Fill Level (as a percentage), and Wasted Space (as a percentage). This screen also
indicates whether the space reclamation process is in progress for a specific Disk Extension media.
3 Select a Disk Extension media on which to reclaim wasted space.
4 Click Apply.
You are prompted that space reclamation can only be performed on one Disk Extension media at a time,
that this process requires use of two physical drives, and that the process may take several hours to
complete.
Note
Space reclamation can only be performed on one Disk Extension media at a time, that
this process requires use of two physical drives, and that the process may take
several hours to complete.
Note
Space reclamation can only be performed on one Disk Extension media at a time. If
the Space Reclamation Currently in Progress field displays a barcode, then space
reclamation is underway on the specified Disk Extension media. You cannot initiate
another space reclamation request until the pending operation is complete. Space
reclamation can take several hours to finish.
Note
If the selected Disk Extension media is scheduled for certain operations, you may
receive a failure message indicating that the system is unable to start the space
reclamation process at this time. If this happens, wait for the scheduled operation to
complete before starting the space reclamation process. Operations that may prevent
space reclamation and cause this failure message to appear include: storing copies of
virtual media files.
