Description
in the queue have been processed, the subsystem
will undergo a short reset at which time the
correctable error will be permanently corrected.
Y This error code indicates that the system
experienced a compare error between the redundant
shared memory copies. The two word queue entry
found in the shared-memory controller error queue
will be placed in the event extended info area. After
all entries currently in the queue have been
processed, the subsystem will undergo a short reset,
at which time an attempt will be made to sync the
two copies of memory (if available) to see if the
error was transient. If the error is permanent, non-
volatile memory must be invalidated. Single
miscompare can be recovered by selecting one of
the two versions of the data and syncing both sides
to that version.
N This event code indicates that the a reset was
initiated due to excessive errors on the
microprocessor local bus.
N This error code indicates that the system
experienced a parity error during a DMA Operation.
N This error code indicates that an inconsistancy was
detected in one of the volume set clusters seed
values, fsb or rbtables. The migration bypassed this
cluster. This could be the result of a r6 restore
consistency posting temporary data to the cluster,
the data in the cluster will remain bad until the data
is reposted by the cache. In the mean time all reads
for data will be satisfied by the cache. After the
cache repost the data may then be successfully
migrated.
Y This error code indicates that the IO Expander
containing the warm boot bit did not power-on in
the correct default condition or that attempts to set
the warm boot bit in the IO Expander failed.
N This is a system change event posted to the log
when shutdown has completed sucessfully; i.e., the
volume set is no longer attacheddevice number field
in log record is volume set number (system change
event)
N This is an error detected by the processor which
caused the processor to vector to the software fault
isr. The controller always resets following this log
entry. This error is caused by illegal instruction
fetches, divide by zero, or other illegal processor
activity.
N This is an error detected by the processor which
caused the processor to vector to the hardware fault
isr. The controller always resets following this log
entry. This error occurs when the microprocessor
attempts an illegal interrupt vector.
N An error occurred on the disk interface. These may
occur during disk hotplug. More detailed status is
available in the event expanded information.
N This is an error detected by the startupSystem when
the current RAM config is not large enough to hold
the NV image stored on disk. Since we do not
support shrinking RAM, this fails the upload
process and causes a new VS to be created. System
state is NO_MAPS.
N An attached disk could not be configured for
command queueing. Command queueing and
disconnects are disabled for this interface.
N This event indicates that the firmware could not
configure the drive to disable disconnects during
