Storage Manager Utilities (SMutil):
SMutil can be used to register and map new logical drives to the operating system and to
verify mapping. It can be installed on all UNIX-based host operating systems, including
AIX, HP-UX, Solaris, and Linux host servers that are attached to a storage subsystem
through Fibre Channel.
The Storage Manager Utilities package contains a number of command-line tools. See 4.6.4,
"Storage Manager utilities" on page 152 for more details.
Controller-based software
The controller-based software consists of:
DS5000 storage subsystem controller firmware and NVSRAM
The controller firmware and NVSRAM are always installed as a pair and provide the
"brains" of the DS5000 storage subsystem. All commands from the SMclient and SMcli
come through this code to cause actions to be performed on the storage devices. The
controller firmware can be thought of as the operating system and application code for the
storage subsystem, and the NVSRAM can be thought of as the configuration of the
application.
Environmental Service Module (SMesm software)
The ESM canister is a component in a storage expansion enclosure that monitors the
environmental condition of the components in that enclosure. The ESM software is
required for automatic ESM firmware synchronization. The ESM firmware controls the
interface between the controller and the drives.
DS5000 storage subsystem drive firmware
The drive firmware is the software that tells the Fibre Channel (FC) drives how to behave
on the FC loop.
4.6.1 Storage subsystem management methods
The storage management software provides two methods for managing storage systems:
Host agent (in-band) management method
Direct (out-of-band) management method
Depending on specific storage system configurations and host systems, either or both
methods can be employed. The management method selected will determine which software
components need to be installed.
