Volume Tasks
Creating a Dynamic Volume
Chapter 4 121
NOTE
• A mirrored volume requires at least two disks. If logging is enabled,
the volume requires at least one additional disk.
• You require a licence to mirror disks other than the root disk.
• Only concatenated or striped volumes can be mirrored.
Options: • 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 enable Dirty Region Logging (DRL) for
the volume, select Enable Logging. VxVM
adds an appropriate number of logs to the
volume.
• 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.
