Creating a Dynamic Volume
Chapter 4 117
NOTE
If no disks are assigned, VxVM uses available space on disks in the
selected disk group.
The data in a concatenated volume is not protected against disk
failure unless the volume is mirrored. At least one additional disk is
required to mirror a concatenated volume.
Concatenated pro volumes are mirrored by default, so a concatenated
pro volume requires more disks than an unmirrored concatenated
volume.
If your system supports root volumes, then it should be noted that
you cannot use a concatenated pro volume for a root volume.
You cannot use a concatenated pro volume for a swap volume.
If a file system is placed on the volume and the Mount at Boot
option is selected, the file system table file automatically updates.
Striped
A striped volume spreads across two or more disks. You have the option
of placing a file system on the new volume or mirroring the volume. You
can create a regular striped volume or a striped pro volume. A striped
pro volume is layered and mirrored.
Layout: Choose Striped or Striped Pro for the
volume layout.
In the Number of Columns field, specify the
number of columns (disks) across which the
volume should be striped. A striped volume
requires at least two disks.
To specify a stripe unit size other than the
default, enter the stripe unit size in the Stripe
Unit Size field. To specify a size unit, attach an
s (sectors), k (kilobytes), m (megabytes), or g
(gigabytes) to the size.
