To create a RAID-5 volume
This procedure creates a RAID-5 volume that is spread across two or
more disks and contains parity information. This procedure also gives
you the option of placing a file system on the new volume.
Step 1. Select the appropriate host machine.
Step 2. Choose File > New > Volume (menu) or Volume Create (Command
Launcher).
Step 3. Complete the New Volume dialog box as follows:
Notes:
• This task requires a disk group name, volume name, volume size, and
volume layout.
• A striped volume requires at least two disks.
• The volume size should be less than or equal to the available free
space on the disk(s).
• If no disks are assigned, the Volume Manager uses available space on
disks in the selected disk group.
• The data in a striped volume is not protected against disk failure
unless the volumeis 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.
• You cannot use a striped pro volume for a root or swap volume.
• If a file system is placed on the volume and the Mount at Boot option
is selected, the file system table file is automatically updated.
Disk Group Name: Either accept the default disk group or click Browse
to select another disk group.
Volume Name: Type the new volume’s name (or accept the default
name).
