stripe(8)
NAME
  stripe - Stripes a file across several volumes in an AdvFS domain.

SYNOPSIS
  /usr/sbin/stripe -n  volume_count filename

OPTIONS
  -n volume_count
      Specifies the number of volumes the striped file crosses. The number of
      volumes must be greater than one.

OPERANDS
  filename
      Specifies the name of the file to stripe.

DESCRIPTION
  The stripe utility enables you to improve the read/write performance of a
  file. The stripe utility directs a zero-length file (a file with no data
  written to it yet) to be spread evenly across several volumes within an
  AdvFS domain.	 As data is appended to the file, the data is spread across
  the volumes. AdvFS determines the number of pages per stripe segment and
  alternates the segments among the disks in a sequential pattern.

  Existing, nonzero-length files cannot be striped using the stripe utility.
  To stripe an existing file, create a new file, use the stripe utility to
  stripe the new file, and copy the contents of the file you want to stripe
  into the new striped file. After copying the file, delete the nonstriped
  file.

  Once a file is striped, you cannot use the stripe utility to modify the
  number of disks that a striped file crosses. To change the volume count of
  a striped file, you can create a second file with a new volume count, and
  then copy the contents of the first file into the second file. After
  copying the file, delete the first file.

RESTRICTIONS
  You cannot stripe a nonzero-length file or a file that is already striped.

EXAMPLES
   1.  The following example stripes the file abc across three volumes in the
       same AdvFS domain:
	    # stripe -n 3 abc

   2.  The following example stripes an existing, nonzero-length file, foo,
       across three volumes in the same AdvFS domain.  First a new file,
       newfoo, is created and striped. Then, the contents of file foo are
       copied to the new, striped file:
	    # touch newfoo
	    # stripe -n 3 newfoo
	    # cp foo newfoo
