Description 

542/0x21e 

Disk interface is down 

Y 

Disk interface, 

disk or controller 

Disk interface 

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. 

543/0x21f 

Lost flash log entry 

Y 

Ignore 

Controller flash 
log 

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. 

544/0x220 

Backend channel hardware 
failure 

Y Failing 

controller Backend 

channel 

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. 

545/0x221 

Maintenance reset 

Y 

Ignore.  These 

occur 

periodically. 

controller 

N 

This reset is performed periodically to scrub ECC 
errors from NV memory. 

546/0x222 

Disk dropped for map data 

Y 

Failing disk 

Disk 

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. 

547/0x223 

Using spare map disk index 
region 

Y 

Failing disk 

Disk 

N 

An error in the primary map disk index data and the 
spare copy of the data is being used. 

548/0x224 

Event log structure corrupted 

Y 

 

controller 

N 

The Event log structure in NVRAM was determined 
to be corrupt.  The event log has been reset and any 
contents have been lost. 

549/0x225 

Front End FC Link Up Event 

Y 

 

controller 

N 

The Front End Fibre Channel port is now up.  The 
topology that was acquired is in the extended log 
information. 

550/0x226 

Front End SCSI Queue Full 
defected 

Y 

 

controller 

N 

The Front End Fibre Channel port has reached a 
SCSI QUEUE FULL condition. 

551/0x227 

Decoder lock exclusive lock 
grant timed out. 

Y 

Ignore.  Lab 

only. 

none 

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. 

552/0x228 

Decoder lock request was 
deferred. 

Y 

Ignore.  Lab 

only. 

none 

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. 

553/0x229 

Decoder deferred lock request 
was granted. 

Y 

Ignore.  Lab 

only. 

none 

N 

The cross controller lock module granted a lock 
request that had previously been deferred. 

554/0x22a 

Decoder deferred lock was 
released. 

Y 

Ignore.  Lab 

only. 

none 

N 

The sequencer released a decoder lock that was 
originally deferred when it was requested from the 
cross controller lock module. 

555/0x22b 

Disk interface Check-
Condition error 

Y Ignore Disk, 

LCC, 

Disk interface 

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. 

556/0x22c 

Power Switch Failed 

Y 

Ignore 

Midplane 

N 

The power switch’s redundant switch outputs are 
inconsistent.  To repair this problem, the midplane 
must be replaced. 

557/0x22d 

Map disk dropped 

Y 

Ignore 

Disk 

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. 

558/0x22e 

Map disk added 

Y 

Ignore 

Disk 

Y 

The Dump Disk Manager has added a map disk. 

559/0x22f 

Map disk reduplex complete 

Y 

Ignore 

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.  

560/0x230 

Map disk removed 

Y 

Ignore 

Disk 

N 

The Dump Disk Manager has removed a map disk. 

561/0x231 

Backend Disk Initialization 
Failure 

Y 

Ignore 

Backend 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. 

562/0x232 

Backend Invalid BlockSize 
Disk 

Y 

Ignore 

Backend Disk 

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).
