Re: Disk failure procedure

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.
