which will be described as part of this software’s installation process. See the rdac
man page for details, and to determine how RDAC provides redundant path

Recovery Guru
Ideally, your RAID Module(s) are operating normally; thus, status information
reported for modules, LUNs, drives, and controllers is Optimal. However, if your
module has operating problems you may notice error messages on your console or
in Message Log. Therefore, any time you suspect a component problem or failure,
select Recovery Guru.
Caution – Always select Recovery Guru before attempting any manual recovery
procedure. Incorrectly performing a procedure or performing the wrong procedure
could cause equipment damage or data loss. Recovery Guru analyzes the problem
and provides the appropriate steps to correct the problem.
Because Recovery Guru's diagnosis takes into account each RAID Module's
configuration (that is, the number and type of controllers, and the relationship
between RAID Level and drive groups), its step-by-step instructions ensure that you
are correcting the right problem. For an example of using Recovery Guru to recover
from two drive failures, see “Example – Recovering From Drive Failures.”
