Creating a mirrored-stripe volume

A mirrored-stripe volume mirrors several striped data plexes. A mirrored-stripe volume requires space to be available on at least as many disks in the disk group as the number of mirrors multiplied by the number of columns in the volume.

To create a mirrored-stripe volume, use the following command:

# vxassist [-b] [-g diskgroup] make volume length \
  layout=mirror-stripe [nmirror=number_of_mirrors] \ 
  [ncol=number_of_columns] [stripewidth=size]

Specify the -b option if you want to make the volume immediately available for use.

Alternatively, first create a striped volume, and then mirror it. In this case, the additional data plexes may be either striped or concatenated.
