Message
72 CACHE ERROR <n>
IGNORE? <=NO, >=YES
73 CACHE HARDWARE
BATTERIES MISSING
80 REPLACEMENT
DRIVE FOUND BOX
#<n> BAY <n>
Type Description
User input
During power up, data was
found in the cache that
could not be flushed to the
hard drives. The reason
is either because the data
does not belong to this
array controller (the cache
module was moved from a
different array controller) or
the cache data is partial
(the rest of the data is in
another cache module that
was removed from the array
controller). This error could
occur if cache modules are
moved improperly.
Error
The cache module does not
have its required batteries
attached to it.
Informational A SCSI hard drive that was
previously missing or failed
has now been replaced
with a working SCSI drive.
Action
If <n> = 1.1 or 1.2:
There is currently only one
cache module in the array
controller, but the controller
was previously configured
with a second cache module
that is now missing.
If <n> = 2.1 or 2.2: A
second cache module was
added to this controller,
but it contains data from its
previous array controller.
If <n> = 2.3: The single
cache module on this array
controller was replaced,
but with cache module
containing data from a
different array controller.
Return the cache module to
its original array controller,
power on the system without
allowing any host I/O, and
wait for cache data to be
written to hard drives. The
system can be powered
off and the cache module
moved to the new location.
< = no. The array controller
will halt.
> = yes. Cache data will be
erased and operation of the
array controller will continue.
If the failure occurred on
the standby array controller,
remove the standby array
controller, remove cache,
attach cache batteries,
replace the cache modules,
wait 10 seconds, and then
reinsert the array controller,
ensuring that it is fully seated
in the chassis.
If the failure occurred on the
active array controller, wait
until downtime is available.
Power off the MSA, remove
the array controller, replace
the cache modules, and
reinsert the array controller,
ensuring it is fully seated in
the chassis.
Should the issue persist,
contact HP support.
