RE: Disk failure procedure -- MIDRANGE-L

DDxxx are deceiving.  D05 is the correct location of the failed drive.
Plus, when you do the remove, it'll blink the light on the right drive. 

The serial is usually accurate on the last five digits or so - it's on a
sticker on the drive.

Subject: Disk failure procedure

I have a disk that has failed on my model 270.  I am just a little fuzzy
on the the replacement.  I have another drive that I can install.  My
problem is that I don't know which drive to replace.  System Operator
message queue has the following:

Unit    6 with device parity protection not fully operational.

Cause . . . . . :   Unit    6 is part of a disk unit subsystem with 
device   
  parity protection.  Unit    6 requires service. The data has been 
saved.   
  Reduced performance, machine checks, and possible data loss can occur 
if   
  this condition is not corrected.  The following information identifies
the
  unit requesting 
service:                                                   
     Disk serial number:               
68-0CF6ADE                            
     Disk type:                        
6718                                  
     Disk model:                       
070                                   
     Device resource name:             
DD006                                 
 



 Disk status shows the following:

             Serial                  Resource  Hardware      
 ASP  Unit   Number      Type Model  Name      Status        
   1     1   02-35300    6718  074   DD001     DPY/Unprotected
   1     2   02-015B2    6718  074   DD004     DPY/Unprotected
   1     3   02-03760    6718  074   DD002     DPY/Unprotected
   1     4   02-03423    6718  074   DD003     DPY/Unprotected
   1     5   68-0D0E009  6718  070   DD005     DPY/Unprotected
   1     6   02-0CF6ADE  6718  070   DD006     DPY/Failed    

Do the unit #'s listed here represent the position in the "cage" these
drives are in?  The only reason I ask is that when I look at the
hardware details for unit #6 I see the following:

 Type. . . . . . . . . . . . : 6718      
 Model . . . . . . . . . . . : 070       
 Level . . . . . . . . . . . : 5         
 Serial Number . . . . . . . : 02-0CF6ADE
 Resource Name . . . . . . . : DD006     
                                         
 Physical location:                      
  Frame ID . . . . . . . . . : 1         
  Card position. . . . . . . : D05       
  Device position. . . . . . :           
                                         
"Card Position" D05 seems to point me to the 5th slot in the cage,
rather than the 6th.  I don't want to yank the wrong one. 

Also, where do I find the "serial number" that is listed in the detail? 
The serial number reported in QSYSOPR message queue is different than 
the detail on disk status (68-0CF6ADE .vs   2-0CF6ADE) Is it on the 
drive itself so I can double check the it before I replace it?

Thanks.

Pete Helgren
