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
AutoPATH_ID
An ID which HDLM assigns to a path when the system is started or when path
configuration is performed. 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.
