Raid Drive Options - Sun Microsystems Sun Fire X4450 Installation Manual

The configuration procedure is different for each supported controller card. For
example, a Sun StorageTek HBA card has many more options for RAID
configuration than an LSI HBA card. Configure the RAID depending on your needs
as shown in
Note – Configuring the Sun Fire X4450 server RAID is optional, by default the
Solaris Pre-Install image is configured in a non-RAID configuration. If anything
other than a basic Mirror RAID is required, it is recommended to perform a fresh
install of the Solaris operating system (or other OS) in the desired RAID
configuration.
