Why Run a SCSI Devices Test?
If you check the SCSI hard-disk drive to determine the
amount of available space, the operating system will prob-
ably report problem areas. Problem areas on hard-disk
drives are common, because most hard-disk drives have a
small amount of space that is not usable. The hard-disk
drive keeps a record of this space so that the computer will
not attempt to use it. Identification of unusable disk space,
unless it is an unusually large amount (over five percent of
the possible total), should not be regarded as a cause for
testing the hard-disk drive.
These are the most common symptoms that might prompt
you to test a SCSI device:
•
A SCSI hard-disk drive fails during the boot routine.
•
Seek errors are reported by the operating system or
application programs.
•
An error message appears on the screen stating that
the computer cannot read from or write to a SCSI
device.
•
Data on a SCSI device is corrupted or lost; this prob-
lem may be intermittent. Once saved by a program,
files cannot be properly recalled.
O
ther Test Group
The subtests in the Other Test Group verify that the
embedded server management (ESM) system is working
properly. The ESM system interacts with the system
BIOS and operating system to ensure that critical param-
eters, such as temperature, are monitored and that
appropriate action is taken if a problem is detected.

Subtests
The three subtests in the Other Test Group and the func-
tions they test follow:
•
ESM Firmware Status
Tests to make sure the ESM software was down-
loaded correctly and that the system is operational.
•
ESM Interface Test
Tests the interface between the host system and the
ESM system to ensure that all bits in the data port
function correctly.
•
ESM Sensor Test
Verifies the current measurements of the ESM
sensors.
Why Run an Other Test?
These are the most common symptoms that might prompt
you to run the ESM subtests in the Other test group:
•
If the Dell HIP server management program returns
a warning dealing with server management
•
If you want to verify that all voltages in the system
are being reported properly
