Description
520/0x208
The over temperature error bit
is set
Y Power Supply Y The over current error bit is set in the power supply
expander
521/0x209
The under voltage error bit is
set
Y Power Supply Y The under voltage error bit is set in the power
supply expander
522/0x20a
Dram text area cksum error Y Controller Y The DRAM Text area checksum does not match the
checksum calculated during initialization. A bgm
timer polls to check the CKSUM once every hour.
523/0x20b
Software address warning Y Controller N This warning indicates that there is switch conflict
in the JBOD enclosures. Two or more enclosure
switches are set to the same address.
524/0x20c
LCC switch address warning Y Controller N This warning indicates that there is an LCC switch
mismatch within a JBOD enclosures.
525/0x20d
Power supply not present Y Power Supply Y This warning indicates that the power supply is not
present
526/0x20e
Map Disk Event Y Controller N This error code indicates that the Topology Manager
MAP DISK code had an event that it has logged.
The defined events are REDUNDANT MAP
DISKS, MAP_DISK_REDUNDANCY_LOSS, and
NO_MAP_DISKS.
527/0x20f
Battery NVRAM backup
command
Y NVRAM
battery charger
N The command sent to enable or disable the batteries
from backing up the NVRAM has failed.
528/0x210
Unsupported host port behavior
table revision
Y Ignore None N The host port behavior table that was read from
chassis NV memory contains an unsupported
revision value. The RAM-based table will be
initialized as empty.
529/0x211
Host Port Behavior table was
initialized as empty
Y None N The host port behavior table was initialized as
empty due to a failure to read the contents from
chassis NV storage.
530/0x212
Firmware download failed Y Ignore. These
should be
detected by the
download utility.
none N A firmware download operation failed. The details
of the failure are included in the event unique
section of the event and other events logged in
conjunction with this one.
531/0x213
AutoFormat Event Occured Y Ignore unless no
Operator activity
Disk Drive,
Back End FC
Link
N An AutoFormat event was logged, this is caused
either by a backend format of an internal drive
beginning or completing. Look as the associated
data for drive and status.
532/0x214
Power supply is not connected
to an AC source
Y Power Supply Y This warning indicates that the power supply is not
connected to an AC source.
533/0x215
Some non-critical midplane
eeprom data was not restored.
Y Midplane
EEPROM
N This warning indicates that some non-critical
eeprom data was not restored during the automatic
restore process. The user should be able to replace
this data by hand. (Licenses, mode parms, Host port
behavior, etc.
534/0x216
Automatic midplane repair
failed.
Y Midplane
EEPROM
Y This warning indicates the automatic midplane
eeprom repair process has failed because of bad
NVSRAM data. The repair can not be done.
535/0x217
Temp sensor exceeded warning
temperature.
Y Controller
Temp Sensor
Y The temperature sensor has exceeded the
recommended temperature for asserting an over-
temp warning.
536/0x218
Temp sensor exceeded
shutdown temperature.
Y Controller
Temp Sensor
Y The temperature sensor has exceeded the
recommended temperature for issuing a controller
shutdown.
537/0x219
Temp sensor is now in range. Y Controller
Temp Sensor
N The temperature sensor had exceeded the
recommended temperature for asserting a warning.
The temperature has now come back down within
range. There is 3 degrees C of hysteresis.
538/0x21a
Disk interface online. Y Ignore Disk interface N A disk interface has come online and is functional.
This occurs normally during reset or reconfiguration
(hotplug).
539/0x21b
Disk interface device
discovered.
Y Ignore Disk interface N A device has been discovered on a disk interface
during reset or reconfiguration (hotplug). This is
normal.
540/0x21c
Disk interface device logout Y Ignore Disk Interface N The login to a device on a disk interface has been
closed. This occurs normally during reconfiguration
(hotplug).
541/0x21d
Disk interface error count has
incremented
Y Ignore, unless
occurring
frequently
Disk interface N The count of link-level errors on a disk interface has
incremented. This can occur under normal
circumstances (especially with disk hotplug), so it
does not indicate a problem unless it occurs
frequently.
