arumon.nlm
The Array Monitor utility, which performs the following functions:
■
Monitors the array driver for error conditions and displays the
error messages on the server console. The messages are also
broadcast to any client locations selected by the operator.
■
Automatically starts the Reconstruct utility ( arurec.nlm ) if a
drive fails in an array that contains a spare.
■
If a function is scheduled, loads the Scheduler utility
(
arusched.nlm ) when the server starts.
The Array Monitor utility must be loaded at all times and only one
instance may be loaded. When you set up the initial arrays on a
server, the Administrator utility automatically inserts the load line
for
arumon.nlm in the autoexec.ncf file, ensuring the Array Monitor
utility loads whenever the server starts.
arurec.nlm
The Reconstruct utility, which runs the data reconstruction function
for
aruadmin and arusched . In mirrored arrays, this utility remirrors
one or all down drives. In RAID 5 arrays, the utility uses parity and
user data on the good drives to reconstruct data on a down drive.
arusched.nlm
The Scheduler utility, which performs Verify, Reconstruct, and Spare
Test operations scheduled by
aruadmin . If an operation is scheduled,
arumon loads the Scheduler utility when the server starts. The
Scheduler utility sleeps until the scheduled time of the operation.
aruver.nlm
The Verify utility, which runs the array verification function for
aruadmin and arusched . This utility verifies the consistency of data
on mirrored and RAID 5 arrays.
