140 Command Console V2.5 User Guide
regeneration The process of recreating all or a portion of the data from a
failed device using the surviving data and parity from the other
virtual disk members.
In most controllers, data from all members remains available
during regeneration, and the user is unaware that regeneration is
occurring, except for a slight reduction in performance.
Regeneration of an entire disk member is called reconstruction.
Data regeneration occurs under one of the following conditions:
■ The controller detects a hard read error on a virtual disk
member. In this case, the controller transparently corrects
the data and continues the read operation.
■ The controller detects that a virtual disk member failed. In
this case, the controller completely reconstructs the failed
member.
SCSI (Small Computer
System Interface)
An industry-standard parallel bus used to interconnect systems
and physical devices.
SCSI device A computer, a host adapter, a peripheral controller, or any
storage element that can be attached to a SCSI bus.
SCSI ID See target ID.
shadowing See mirroring.
spare A device state indicting that a device is designated as a hot
spare for a failed device within a redundant RAID virtual disk.
If a virtual disk member fails, the controller automatically
replaces it with a spare device from the pool of spare devices.
The term is also used to refer to a spare device itself.
storageset HS-series controller term for device group.
Storage Window The Storage window is a Client component that provides a
graphical interface for configuring and monitoring to a selected
subsystem.
