HP StoreEver ESL G3 Tape Libraries - Manual (Page 161)

slots that belong to a partition are not all adjacent to one other, and the partition is fragmented.
Fragmentation can make bulk loading media more difficult.
Defragmenting partitions reassigns slots in the library so that all slots in each partition are physically
contiguous with one another. In addition, media is moved as needed to ensure that it resides in
the correct partition. In the process, tapes are first moved from their old location to the I/E station
and then are moved to their new location in the library.
Depending on the size of the library, defragmenting partitions can be a time-consuming process.
NOTE: Only partitions that contain an I/E station can be defragmented. Also, at least one
magazine in the I/E station must be empty. Partitions that do not contain an I/E station cannot be
defragmented and will be skipped.
Defragmenting partitions
After enlarging a partition or adding an expansion module to the library, check for partition
fragmentation, and then defragment partitions if necessary.
To defragment partitions:
1. Log on as an administrator.
2. Ensure that you are viewing the physical library. From the View menu or in the Managed
Views area of the LMC, select the name of the physical library.
3. Select Tools
→Partitions Defragmentation.
The Partitions Defragmentation window shows a graphical representation of the tape magazines
in the library. Magazines are color-coded to indicate to which partition they belong.
If the library has more than one frame, click the >> and << buttons at the bottom of the window
to display the next or previous frame. If one or more partitions are fragmented, you can
defragment them.
