BOOT
ONLINE
FAIL
During startup, the system
attempted to put the
specified module online. This
operation failed.
The event gives a reason why the
Put Online failed. Examine this
reason and take the appropriate
action. If the reason is DIAGNOSTIC
FAIL, a hardware problem was
found with the module. In this case,
try replacing the module with a
different one.
DISK CHAN
DEGRAD
Errors detected on one of the
disk channels have caused
the
EF2800
to mark the
channel as degraded.
Determine the source of the errors
on the specified disk channel and
replace the faulty hardware.
DRIVE
DOWN
An error occurred with the
drive and it was downed,
removing it from the active
array.
Add a spare to the array or the spare
pool. Then replace the bad drive.
Refer to Section
5.4
..
HW
STATUS
CHANGE
A SM has detected a
significant change in the
status of one of the power
modules.
If the event indicates that the
module has failed or is not present,
install a new module.
OTHER
WWN
UNKNOWN
The host Fibre Channel World
Wide Names (node and port)
previously presented by the
other SM module (which is
currently offline) in this
system are unknown. This
event has two possible
causes:
The online SM module
reporting the event was
replaced or moved while the
system was powered off.
The online SM module had its
flash configuration cleared
(this is where the previously
used WWNs are stored).
The online Storage Manager
module recovers from this situation
by fabricating a WWN for the other
SM module based on its own serial
number. If you see this event, then
you need to verify the WWN
information for the other SM
module on all hosts that access it.
