Glossary - Hitachi XP P9500 User Manual

This glossary explains the terms used in this manual.
A
automatic failback
A function for checking the status of paths at regular intervals, and automatically
placing the status of a path recovered from an error into the Online status.
If a path with an Offline(E) or Online(E) status recovers from an error, an automatic
failback will place the path Online.
Automatic failbacks check the status of paths that were placed in the Offline(E) or
Online(E) status because of an error, but do not check the status of paths that were
placed in the Offline(C) status by executing an offline operation. For details on offline
operations, see offline (Places Paths Offline) on page
AutoPATH_ID
An ID that HDLM assigns to a path during the system startup. Every path has a unique
AutoPATH_ID.
(See also: path)
B
boot disk environment
An environment in which the startup disk is in a storage system instead of in the host.
C
CHA (Channel Adapter)
An adapter for controlling the channels of a storage system.
