INFORMATION A drive enclosure EMU condition report that may require action. This condition is for information
condition only and does not indicate the failure of an element. All condition reports have precedence over
an INFORMATION condition.
initialization A configuration step that binds the controllers together and establishes preliminary data structures
on the array. Initialization also sets up the first disk group, called the default disk group, and
makes the array ready for use.
