Creating a Dynamic Volume
Chapter 4118
NOTE
• A striped volume requires at least two disks.
• If no disks are assigned, VxVM uses available space on disks in the
selected disk group.
• The data in a striped volume is not protected against disk failure
unless the volume is mirrored. At least one additional disk is
required to mirror a striped volume.
• Striped pro volumes are mirrored by default, so a striped pro volume
requires more disks than an unmirrored striped volume.
• If your system supports root volumes, then it should be noted that
you cannot use a striped pro volume for a root volume.
Options: • To mirror the volume, select Mirrored. In
the Total Number of Mirrors field, enter
the total number of mirrors for the volume.
NOTE: Striped pro volumes are mirrored by
default.
To enable logging for a mirrored volume, select
Enable Logging.
• To place a file system on the volume, click
Create a file system and specify the file
system type and mount point in the New
File System dialog box.
• To clear the volume before enabling it for
general use, select Initialize Zero.
• To prevent the creation of a layered
volume, select No Layered Volumes. In
cases where a layered volume layout is
appropriate, VxVM can create a layered
volume when a non-layered layout is
specified. This option ensures that the
volume has a non-layered layout. If a
layered (Pro) layout is selected, this option
is ignored.
