Table C-1: Warning Events
Event Definition
IFSII_FDR23
BATT FAIL
INFO
A warning condition in the
battery pack and/or charging
interface has been detected.
REPLACE
BATTERY
ARRAY
CRITICAL
The battery is approaching its
3 year life span.
One or more drives were
downed and the array is
online but no longer
fault-tolerant.
DRIVE
DOWN
An error occurred with the
drive, causing the drive to go
down. Thus, removing it from
the active array.
SPARE
UNUSABLE
The drive still contains meta-
data that must be cleared.
Recommended
Action
Replace the battery.
Replace the battery.
Add a spare to the array or to
the spare pool and replace the
bad drives. Refer to Adding a
Dedicated Spare or Adding a
Spare to the Spare Pool.
Add a spare to the array or to
the spare pool and replace the
bad drive. Refer to Adding a
Dedicated Spare or Adding a
Spare to the Pool Spare.
Clear the metadata from the
spare drive. Refer to Clearing
Metadata from a Drive.
SMART
EVENT
A disk drive IEPC predictive
failure message was received.
NO actions by the controller
are taken on the drive for
these events.
Run diagnostics available from
the operating system on the
affected drive. Replace the
drive if necessary.
ARRAY
OFFLINE
More than 1 drive in a RAID 0
or volume set went down,
bringing the array to an offline
state. This array is no longer
accessible by the host.
Replace the bad drive and
restore the data from backup.
VOLT/TEMP
WARN
The analog to digital convertor
detected a temperature and/
or voltage in the warning
range.
Check the ambient
temperature.
UNWRITABLE
CACHE
The SDRAM cache has
battery backed up data and
the arrays assigned to this
data are not present.
Determine which drives are
missing and reinstall them.
Or, select Yes when asked
to discard data.
SDRAM
CORR ECC
A correctable single bit
SDRAM ECC error.
If this error occurs frequently,
replace the memory.
KILLED
OTHER
This controller is forcing a
shutdown (killing) the other
controller in an active-active
configuration.
This is caused by incompatibil-
ity between versions of firmware
or disk or host channel ID
conflicts.
Either verify that the firmware
versions are the same (refer to
“Displaying Hardware and
Configuration Information” or
resolve the disk or host channel
ID conflicts (refer to “Configur-
ing the SCSI Disk Channels”
or “Configuring the Host
Channels”.
