Description 

70/0x46 

Disk Interface Command 
Timeout 

Y 

N.A. 

None 

Y 

A backend device did not complete a command 
within the allotted time. 

71/0x47 

Disk Interface Hot Plug 

N 

N.A. 

None 

N 

A command was aborted by a disk hotplug or by 
error error recovery for some other command. 

72/0x48 

Host Write Collision With 
Failed Cache Post 

Y 

ignore - see 

accompanying 

errors 

None 

N 

A write launched from cache but ended with a non-
SUCCESS status; this caused cache to mark the 
write cache entry as RETRY which means it is stuck 
in cache. A flush is required by a new FUA write. 
One of the pages from the flush is stuck in cache 
and the response is to fail the new write. 

73/0x49 

Disk Drive Defect List Error 

Y 

Single 

Occurrance 

Disk Drive 

N 

The disk drive returned a status of 
CHECK_CONDITION, HARDWARE_ERROR, .  
The PDD’s retries are exhausted or the I/O is not 
retryable.  The drive may need to be formatted. 

74/0x4a 

Disk Drive Format Error 

Y 

Single 

Occurrance 

Disk Drive 

N 

The disk drive returned a status of 
CHECK_CONDITION, MEDIA_ERROR, 
FORMAT CORRUPTED/FAILED.  May be cause 
for immediate failure. The PDD did not attempt to 
send a REASSIGN BLOCKS command.  The drive 
may need to be formatted. 

75/0x4b 

Invalid/unsupported hierarchic 
LUN reference 

N 

Ignore - Host 

LUN addressing 

problem 

None 

Y 

The host specified an 8-byte hierarchic LUN 
reference that contained either an unsupported 
address mode or made use of hierarchy levels that 
the subsystem does not support. 

76/0x4c 

Disk Interface State Error 

Y 

N.A. 

None 

N 

The backend disk interface hardware or software 
state information was incorrect for observed 
activity. 

77/0x4d 

Write Sequence In Cache 
Broken By Host Abort 

N 

N.A. 

None 

N 

A part of a write cache stream was aborted by the 
host.  The failed write was forced because the 
operation could not be completed. The host should 
retry the operation. 

78/0x4e 

Silent Disk Drive Error 
Recovery 

N 

N.A. 

None 

N 

On a previous attempt(s), the drive failed the I/O.  
(Usually due to hot plug.) The PDD retried the I/O 
and the drive returned good status. We do not log a 
recovered error because the original error was not 
logged.  We report GOOD status to the host. 

79/0x4f 

Check Condition From Disk 
Drive With No Sense 

Y Single 

Occurrence 

Disk Drive 

N 

The disk drive returned a check condition with no 
sense data.  The PDD’s retries are exhausted or the 
I/O is not retryable. 

80/0x50 

Disk Drive Failed Start Unit 
Command 

Y Single 

Occurrence 

Disk Drive 

N 

The disk drive returned bad status for a start unit 
command.  The PDD’s retries are exhausted. 

81/0x51 

Unexpected Disk Drive Status 

Y 

Single 

Occurrance,

problem 

Disk Drive, 
Controller, Disk 
Interface 

N 

The disk drive returned a status of SCSI_BUSY, 
RESERVATION_CONFLICT, or some 
undecodable status.  The PDD’s retries are 
exhausted or the I/O is not retryable. 

82/0x52 

Insufficient resources for LUN 
operation. 

N 

N.A. 

None 

N 

There is insufficient physical disk storage capacity 
present for the LUN operation that was requested.  
More disks must be added to the subsystem before 
the operation can be successful. 

83/0x53 

Microcode Changed Unit 
Attention 

N 

N.A. 

None 

N 

New controller microcode was just installed. 

84/0x54 

Create LUN can’t get LUN 
WWN seed 

Y 

None allowed 

None 

Y 

The create LUN operation cannot be completed 
because the memory device that holds the seed for 
the LUN WWN has either failed or cannot return the 
requested data.  LUN WWNs cannot be made 
unique without this data. 

85/0x55

Y 

See drive vendor 
recommendation 

Disk Drive 

N 

On a previous attempt(s), the drive failed the I/O. 
The PDD retried the I/O and the disk drive returned 
a status of CHECK_CONDITION, 
RECOVERED_ERROR 

86/0x56
