Sun Cluster Software Installation Guide for Solaris OS

Mirroring the Root Disk

Mirroring the root disk prevents the cluster node itself from shutting down because of a system disk failure. Four types of file systems can reside on the root disk. Each file-system type is mirrored by using a different method.

Use the following procedures to mirror each type of file system.

Caution – Caution –

For local disk mirroring, do not use /dev/global as the path when you specify the disk name. If you specify this path for anything other than cluster file systems, the system cannot boot.
