Planning Volume Management

This section provides the following guidelines for planning volume management of your cluster configuration:

Oracle Solaris Cluster software uses volume manager software to group disks into device groups that can then be administered as one unit. You must install Solaris Volume Manager software on all nodes of the cluster.

See your volume manager documentation and Configuring Solaris Volume Manager Software for instructions about how to install and configure the volume manager software. For more information about the use of volume management in a cluster configuration, see Multihost Devices in Oracle Solaris Cluster Concepts Guide and Device Groups in Oracle Solaris Cluster Concepts Guide.

Guidelines for Volume Manager Software

Consider the following general guidelines when you configure your disks with volume manager software:

See your volume manager software documentation for disk layout recommendations and any additional restrictions.

Guidelines for Solaris Volume Manager Software

Consider the following points when you plan Solaris Volume Manager configurations:

UFS Cluster File System Logging

Logging is required for UFS cluster file systems. Oracle Solaris Cluster software supports Solaris UFS logging. See the mount_ufs(1M) man page for more information.

Mirroring Guidelines

This section provides the following guidelines for planning the mirroring of your cluster configuration:

Guidelines for Mirroring Multihost Disks

Mirroring all multihost disks in an Oracle Solaris Cluster configuration enables the configuration to tolerate single-device failures. Oracle Solaris Cluster software requires that you mirror all multihost disks across expansion units. You do not need to use software mirroring if the storage device provides hardware RAID as well as redundant paths to devices.

Consider the following points when you mirror multihost disks:

For more information about multihost disks, see Multihost Devices in Oracle Solaris Cluster Concepts Guide.

Guidelines for Mirroring the ZFS Root Pool

Oracle Solaris ZFS is the default root file system in the Oracle Solaris 11 release. See How to Configure a Mirrored Root Pool (SPARC or x86/VTOC) in Oracle Solaris 11.1 Administration: ZFS File Systems for instructions about how to mirror the ZFS root pool. Also see Chapter 4, Managing ZFS Root Pool Components, in Oracle Solaris 11.1 Administration: ZFS File Systems for information about how to manage the different root pool components.

For maximum availability, mirror root (/), /usr, /var, /opt, and swap on the local disks. However, Oracle Solaris Cluster software does not require that you mirror the ZFS root pool.

Consider the following points when you decide whether to mirror the ZFS root pool:
