Navigation tree
Provides access to the HSxxx Storage window
Displays the status of your systems in a hierarchical order.
Navigation window
It contains the Navigation tree and the menu options for
configuring pager notification and the Navigation tree.
network connection
A remote connection from the Client to multiple subsystems
using Agent over a TCP/IP-compatible network. Network
connections enable you to concurrently monitor thousands of
subsystems over a LAN or WAN anywhere in the world.
nonredundant
For HS-series controllers, a single-controller configuration.
The term is also sometimes used to refer to a RAID level that
does not provide fault tolerance (for example, RAID 0).
normal
In mirrored virtual disks, a member state that indicates that a
member contains exactly the same data as the other members do
parameter
A setting or value that defines a particular operating
characteristic of a device, virtual disk, controller, or subsystem.
parity
Binary value calculated from user data used to detect if
associated data becomes corrupt. Parity can also be used to
correct corrupted data. Striped parity virtual disks use parity to
improve data availability.
parity check
A virtual disk state that indicates that the controller is checking
the integrity of a virtual disk's data.
partition
A logical division of a virtual disk, represented itself as a virtual
disk to the host. Command Console enables the creation of
virtual device partitions, but they are transparent to the user.
password
A code string used by the Client with network connections to
restrict configuration functions to privileged users. Passwords
are set at the Agent at each host.
pedestal
A desk-side, floor-standing, storage enclosure capable of
housing one or more controllers and associated devices to make
up a complete subsystem.
physical device
A storage component installed in a subsystem.
physical disk
A storage component with rotating magnetic media that is
installed in a subsystem.
