Creating RAID-5 Volumes
Caution - Do not create volumes larger than 1 Tbyte if you expect to run
the Solaris software with a 32-bit kernel or if you expect to
use a version of the Solaris OS prior to the Solaris 9 4/03
release. See Overview of Multi-Terabyte Support in Solaris Volume Manager for more information about large volume support in Solaris
How to Create a RAID-5 Volume
Before You Begin
Check Prerequisites for Creating Solaris Volume Manager Components and Background Information for Creating RAID-5 Volumes.
- To create a RAID-5 volume, use one of the following methods:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose Action⇒Create Volume. Then, follow the steps in the wizard. For more information, see the online help.
Use the following form of the metainit command:
# metainit wolume-name -r component component component -i interlace-value
Specifies the name of the volume to create.
Specifies to create a RAID-5 volume.
Specifies a slice or soft partition to include in the RAID-5 volume. At least 3 components are required.
Specifies an interlace value.
For more information, see the metainit(1M) man page.
Example 15-1 Creating a RAID-5 Volume of Three Slices
In this example, the RAID-5 volume d45 is created with the -r option
from 3 slices. Because no interlace value is specified, d45 uses the default
of 512 Kbytes. The system verifies that the RAID-5 volume has been set
up and begins initializing the volume.
You must wait for the initialization to finish before you can use
the RAID-5 volume.
# metainit d45 -r c2t3d0s2 c3t0d0s2 c4t0d0s2
d45: RAID is setup
To prepare the newly created RAID-5 volume for a file system, see
Chapter 18, Creating UFS, TMPFS, and LOFS File Systems (Tasks), in System Administration Guide: Devices and File Systems. Some applications, such as a database, do not use a file system.
These applications instead use the raw volume. The application must have its own
way of recognizing the volume.
