## How to Install Solaris Volume Manager

Perform this procedure on each node in the global cluster.

1. Assume the `root` role.
2. Ensure that the `solaris` publisher is valid.

       # pkg publisher
       PUBLISHER                           TYPE     STATUS   URI
       solaris                             origin   online   solaris-repository

   For information about setting the `solaris` publisher, see Set the Publisher Origin to the File Repository URI in Copying and Creating Oracle Solaris 11.1 Package Repositories.

3. Install the Solaris Volume Manager package.

       # pkg install system/svm

## How to Create State Database Replicas

Perform this procedure on each node in the global cluster.

1. Assume the `root` role.
2. Create state database replicas on one or more local devices for each cluster node.

   Use the physical name (`c` N `t` X `d` Y `s` Z), not the device-ID name (`d` N), to specify the slices to use.

       phys-schost# metadb -af slice-1 slice-2 slice-3

   Tip - To provide protection of state data, which is necessary to run Solaris Volume Manager software, create at least three replicas for each node. Also, you can place replicas on more than one device to provide protection if one of the devices fails.

   See the `metadb`(1M) man page and Creating State Database Replicas in Solaris Volume Manager Administration Guide for details.

3. Verify the replicas.

       phys-schost# metadb

   The `metadb` command displays the list of replicas.

Example 4-1 Creating State Database Replicas

The following example shows three state database replicas. Each replica is created on a different device.

    phys-schost# metadb -af c0t0d0s7 c0t1d0s7 c1t0d0s7
    phys-schost# metadb
    flags            first blk      block count
        a       u       16          8192         /dev/dsk/c0t0d0s7
        a       u       16          8192         /dev/dsk/c0t1d0s7
        a       u       16          8192         /dev/dsk/c1t0d0s7
