How to Create a RAID-0 (Concatenation) Volume
Do not create volumes larger than 1Tbyte if you expect to run the Solaris software with a 32–bit kernel. Additionally, do not create volumes larger than 1 Tbyte 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 multi-terabyte volumes in Solaris Volume Manager.
Check Prerequisites for Creating Solaris Volume Manager Components and Background Information for Creating RAID-0 Volumes.
To create a concatenation 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 instructions in the wizard. For more information, see the online help.
Use the following form of the metainit command:
# metainit volume-name number-of-stripes
components-per-stripe
component-names
volume-name
Specifies the name of the volume to create.
number-of-stripes
Specifies the number of stripes to create.
components-per-concatenation
Specifies the number of components each concatenation should have.
component-names
Specifies the names of the components that are used. If more than one component is used, separate each component with a space.
For more information, see the following examples and the metainit ( 1M ) man page.
Example 9.3. Creating a Concatenation of One Slice
# metainit d25 1 1 c0t1d0s2
d25: Concat/Stripe is setup
This example shows the creation of a concatenation, d25.
This concatenation consists of one stripe (the first number 1) composed of a single slice (the second number 1 in front of the slice). The system verifies that the volume has
been set up.
The example shows a concatenation that can safely encapsulate existing data.
Example 9.4. Creating a Concatenation of Four Slices
# metainit d40 4 1 c0t1d0s2 1 c0t2d0s2 1 c0t2d0s3 1 c0t2d1s3
d40: Concat/Stripe is setup
This example shows the creation of a concatenation, d40.
The concatenation consists of four stripes (the number 4), each composed of
a single slice (the number 1 in front of each
slice). The system verifies that the volume has been set up.
