Mapping Solaris Volume Manager Tasks to Solaris Live Upgrade

Solaris Live Upgrade manages a subset of Solaris Volume Manager tasks. Table 2–1 shows the Solaris Volume Manager components that Solaris Live Upgrade can manage.

Table 2–1 Classes of Volumes

Term 

Description 

concatenation

A RAID-0 volume. If slices are concatenated, the data is written to the first available slice until that slice is full. When that slice is full, the data is written to the next slice, serially. A concatenation provides no data redundancy unless it is contained in a mirror. 

mirror

A RAID-1 volume. See RAID-1 volume. 

RAID-1 volume

A class of volume that replicates data by maintaining multiple copies. A RAID-1 volume is sometimes called a mirror. A RAID-1 volume is composed of one or more RAID-0 volumes that are called submirrors.  

RAID-0 volume

A class of volume that can be a stripe or a concatenation. These components are also called submirrors. A stripe or concatenation is the basic building block for mirrors.  

state database

A state database stores information about disk about the state of your Solaris Volume Manager configuration. The state database is a collection of multiple, replicated database copies. Each copy is referred to as a state database replica. The state database tracks the location and status of all known state database replicas. 

state database replica 

A copy of a state database. The replica ensures that the data in the database is valid. 

submirror

See RAID-0 volume. 

volume

A group of physical slices or other volumes that appear to the system as a single logical device. A volume is functionally identical to a physical disk in the view of an application or file system. In some command-line utilities, a volume is called a metadevice.
