Reinitializing a Volume 

Sometimes the data on a volume is obsolete and the volume is needed for
another set of data.  To reinitialize a volume, perform the following
steps:

   1.  Place the volume in loner status by mounting a volume whose master
       is not physically mounted, or by using the CI VSCLOSE command to
       close the volume set.  At the volutil:  prompt, enter a colon, the
       VSCLOSE command and the volume set name:

            volutil::VSCLOSE vname 

   2.  Verify that the data on the volume is no longer needed and can be
       overwritten.

   3.  Mark the volume as free to be written on.  At the volutil:
       prompt, enter the SCRATCHVOL command and the LDEV number:

            volutil:SCRATCHVOL ldev 

   4.  To add the volume to a set and initialize it, use the NEWVOL
       command.  At the volutil:  prompt, enter:

            volutil:NEWVOL sname:vname additional parameters 

To scratch a volume 

The VOLUTIL command SCRATCHVOL puts the volume in scratch status.  An
entry is made in the volume label table to let the operating system know
that someone can write on the volume.

SCRATCHVOL has the following syntax:

SCRATCHVOL {[LDEV =] ldev}

To place the volume BVOL5, whose LDEV number is 23 in scratch status,
enter:

     volutil:SCRATCHVOL 23 

To unscratch a volume 

You may, at some time, unintentionally scratch a volume that still
contains important information.  As long as no one has written on the
volume, you can unscratch it to get the data.  To do so, you can use the
UNSCRATCHVOL command.

To unscratch a volume, at the volutil:  prompt, enter:

     volutil:UNSCRATCHVOL ldev 

For example, to unscratch the volume BVOL5 whose LDEV number is 23,
enter:

     volutil:UNSCRATCHVOL 23
