Description
N A disk interface has been down for longer than the
time allowed for normal recovery. Array function
will continue without use of this channel. This can
be caused by a bad connection to disks (internal or
external), or by a failind disk or controller.
N This event code should only appear in the flash logs.
It indicates that a log entry was lost because the
flash log queue was full when a new event arrived to
be logged. This is expected to be a normal
occurrence, but is logged to show that some
information has been lost.
N An error has occurred which indicates that the disk
interface electronics is failing. It is also possible
that this error could be caused by failing
interconnect hardware.
N This reset is performed periodically to scrub ECC
errors from NV memory.
N An error has occurred accessing the map data index
region of a map disk and the disk will no longer be
used to store map data.
N An error in the primary map disk index data and the
spare copy of the data is being used.
N The Event log structure in NVRAM was determined
to be corrupt. The event log has been reset and any
contents have been lost.
N The Front End Fibre Channel port is now up. The
topology that was acquired is in the extended log
information.
N The Front End Fibre Channel port has reached a
SCSI QUEUE FULL condition.
N The cross controller lock module failed to grant the
decoder's lock in exclusive mode, within the
allowed period, after an obtain request was deferred.
This may indicate a deadlock in the system or that
the system is too busy.
N The cross controller lock module deferred a request
to obtain the decoder's lock. This is normal for
exclusive acquisition but not for shared acquisition.
N The cross controller lock module granted a lock
request that had previously been deferred.
N The sequencer released a decoder lock that was
originally deferred when it was requested from the
cross controller lock module.
N A command sent to a device on a disk interface has
returned a Check Condition status. This can occur
under normal circumstances, so it does not indicate
a problem unless it occurs frequently, or if the Sense
Data indicates a problem.
N The power switch's redundant switch outputs are
inconsistent. To repair this problem, the midplane
must be replaced.
Y The Dump Disk Manager has decided to drop a map
disk due to a disk failure or hotplug event. This
should normally result in a Map Disk Redudancy
Loss warning or No Map Disks warning.
Y The Dump Disk Manager has added a map disk.
N The Dump Disk Manager has finished reduplexing
the map disks. This process begins after a disk is
inserted and is being set up as the second map disk.
N The Dump Disk Manager has removed a map disk.
N One of the backend disks was set to an "Init Failed"
state. This could indicate a significant problem with
the disk, or simply that it needs to be formatted.
N One of the backend disks was set to an "Init Failed"
state because it has an invalid blockSize. This could
mean the disk failed a previous format (0-block
size) or came new from the factory (512-block size).
