Solaris Volume Manager Administration Guide

ProcedureHow to Create a RAID 5 Volume

  1. Check Prerequisites for Creating Solaris Volume Manager Components and Background Information for Creating RAID 5 Volumes.

  2. To create the RAID 5 volume, use one of the following methods:

    • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node, then choose Action->Create Volume and follow the steps in the wizard. For more information, see the online help.

    • Use the following form of the metainit command:

      metainit name -r component component component
      • name is the name for the volume to create.

      • r specifies to create a RAID 5 volume.

      • component specifies a slice or soft partition to include in the RAID 5 volume.

      To specify an interlace value, add the -i interlace-value option. For more information, see the metainit(1M) man page.

Example 15–1 Creating a RAID 5 Volume of Three Slices

# metainit d45 -r c2t3d0s2 c3t0d0s2 c4t0d0s2
d45: RAID is setup

In this example, the RAID 5 volume d45 is created with the -r option from three slices. Because no interlace value is specified, d45 uses the default of 16 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.

To prepare the newly created RAID 5 volume for a file system, see Chapter 16, Creating UFS, TMPFS, and LOFS File Systems (Tasks), in System Administration Guide: Devices and File Systems. An application, such as a database, that uses the raw volume must have its own way of recognizing the volume.
