NAME

       stripe - Stripes a file across several volumes in a file domain

SYNOPSIS

       /usr/sbin/stripe -n  volume_count filename

OPTIONS

       Specifies the number of volumes the striped file crosses. The number of volumes must be greater than one.

OPERANDS

       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 a file 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 sequen-
       tial 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

       The following example stripes the file abc across three volumes in the same file domain: # stripe -n 3 abc The following example stripes an
       existing,  nonzero-length  file,  foo, across three volumes in the same 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
