RE: Disk failure procedure

Thought if it had RAID it was concurrent-enabled.

Note that concurrent maintenance was optional on the 270.

You may have to shut down the box to replace the drive.

Concurrent maint
Remove DDxxx
Concurrent maint
Add DDxxx
Disk recovery menu
Rebuild disk unit data
Select disk to rebuild
Wait an hour
WRKDSKSTS, F11 to ensure no longer "FAILED" and now "ACTIVE"

Done! 

Parity will auto-recover as will the ASP part.

Yes.  I checked the system builder, too.  I was just worried that I 
was going to pull the wrong unit.

OK, with that cleared up, are there instructions for replacing a disk 
unit somewhere?  I looked at the Backup and Recovery guide and the 
System Builder but I don't see any step by step.  I guess I need to do



"Concurrent Maintenance" on the unit to remove it.  Put the new one in



and then ?  Just add it back into the ASP and start parity protection?

And looking in my handy-dandy system builder...

D05 is the fifth from the left on the skinny 270.  D01 is

on the left

and D06 is on the right.

If you have the expansion attached, the disk numbering

starts at the

bottom of that with D08 and goes to the top with D20.

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
