Examples

  In examples 1 and 2, the contents of the data region on the medium
  are not altered or destroyed; in examples 3, 4, and 5, all the data
  on the medium is destroyed.

  1.   $ ANALYZE/MEDIA/BAD_BLOCKS=(4.4.4:3) DBA1:

  The /BAD_BLOCKS qualifier in this example specifies a range of 3
  bad blocks beginning at the physical disk address sector 4, track
  4, cylinder 4.  This range is added to the DBBF.

  2.   $ ANALYZE/MEDIA/LOG DBB1:
       DEVICE DBB1: CONTAINS A TOTAL OF 340670 BLOCKS; 11 DEFECTIVE
       BLOCKS DETECTED.

  The command in this example requests BAD to report the total 
  number of bad blocks recorded in DBBFs for the disk mounted on
  DBB1:. The medium is not exercised or altered in any way.

  3.   $ ANALYZE/MEDIA/EXERCISE/BAD_BLOCKS=(2) DBB1:

  The command in this example adds the bad block specification to 
  the DBBF and then tests the media. The bad block in this example
  is located at logical block number (LBN) 2.

  4.   $ ANALYZE/MEDIA/EXERCISE=KEEP DBA1:

  This command tests the media while preserving the current SDBBF.

  5.   $ ANALYZE/MEDIA/EXERCISE/RETRY DBB1:

  The command in this example directs the device driver to retry soft
  errors.
