Parameter

Qualifier

Example

$ SHOW DEVICE /BITMAP DSA12
Device   BitMap    Size    Percent     Type of   Master  Active
 Name      ID     (Bytes)  Populated   Bitmap     Node
DSA12:  00020007     8364       0%    Minimerge  NODE1     Yes
        00040008     8364       0%    Minimerge  NODE2     Yes
$ DELETE/BITMAP 00020007
      

In this example, the SHOW DEVICE command output lists two bitmaps. The DELETE command deletes the bitmap with an ID of 00020007.
