Message Description Recommended Action
ProLiant storage
unit on SCSI
bus X cabling
error (bus
disabled)
This controller has internal and
external connectors for the same
SCSI bus. Therefore, the SCSI bus
can only be cabled to a storage unit
using the controller’s internal or
external connector. The controller
firmware has automatically disabled
the SCSI bus because the internal
and external connectors were both
cabled to a storage unit.
Check all cable connections. Disconnect the
storage unit cable from the controller’s internal
or external connector.
ProLiant storage
unit on SCSI
bus X – Wide
SCSI transfer
failed – check
cables
Wide data transfers failed on all wide
drives attached to this bus. The
firmware then reverted to narrow
data transfers on these drives. This
may indicate a bad SCSI cable.
Check all cable connections. If there is a
problem, keep replacing cables between the
controller and drives until the problem goes
away.
ProLiant storage
unit on SCSI
bus X is
unsupported.
SMART-2
requires
fast/wide
ProLiant Storage
System – Drives
not activated
The controller may not support the
storage unit attached to the
controller.
Verify that the controller supports the storage
unit connected to the controller. Attach only
storage units that are supported by the
controller.
ProLiant storage
unit on SCSI
bus X cooling fan
malfunction
The fan in the storage unit had an
alarm condition.
Check connections to the fan. If error persists,
replace the fan.
ProLiant storage
unit on SCSI
bus X overheated
condition
The storage unit had a temperature
alert.
Make sure the operating environment of the
storage unit is within specifications. For better
airflow, remove any dust build-up from fans.
ProLiant storage
unit on SCSI
bus X side panel
must be closed
The side panel of the storage unit is
off.
Make sure the side panel of the storage unit is
properly attached.
ProLiant storage
unit on SCSI
bus X redundant
power supply
malfunction
One of the power supplies on the
storage unit is not working.
Check connections. Replace power supply if
necessary.
RIS copies
between drives
do not match
Drives on controller contain copies of
RIS that do not match.
Upgrade ADU to the most recent version.
SCSI Port X Drive
ID X has
exceeded
threshold(s)
Monitor and performance threshold
for this drive has been violated.
Check for the particular threshold that has been
violated.
