General Description 1–15
Fault Management Utility
The Fault Management Utility (FMU) provides a limited interface to
the controller’s fault-management system. As a troubleshooting tool,
you can use FMU to display last-failure and memory-system-failure
entries, translate many of the code values contained in event messages,
and set the display characteristics of significant events and failures.
See “Fault Management Utility,” page 4–17, for more information
about using this utility.
Virtual Terminal Display
Use the virtual terminal display (VTDPY) utility to troubleshoot
communication between the controller and its host, communication
between the controller and the devices in the subsystem, and the state
and I/O activity of the logical units, devices, and device ports in the
subsystem.
See “Using VTDPY to Check for Communication Problems,” page
4–23, for more information about using this utility.
Disk Inline Exerciser
Use the disk inline exerciser (DILX) to investigate the data-transfer
capabilities of disk drives. DILX tests and verifies operation of the
controller and the SCSI–2 disk drives attached to it. DILX generates
intense read and write loads to the disk drive while monitoring the
drive’s performance and status. See “Checking for Disk-Drive
Problems,” page 4–37, for more information about this exerciser.
Configuration Utility
Use the configuration (CONFIG) utility to add one or more storage
devices to the subsystem. This utility checks the device ports for new
disk drives then adds them to the controller’s configuration and
automatically names them. See “Adding Several Disk Drives at a
Time,” page 3–55, for more information about using the CONFIG
utility.
