Re: errpt not clear to me

That invalid data strip is bad to see.  You are correct, the solution is to backup the array; destroy it; rebuild it; and restore it.
 
I know others having this problem before; but it is a rare one for me.  It might be a code issue with the SSA device drivers or something.
 
The reason diags did not see it is because it is a problem with the logical drive not the physical drive.  ssa_health_check picked up on a LUN issue.

hdisk2                   0                       0           Invalid data strip
 
It looks to me like even though the certify process didn't find an error I may
have to backup my data, delete the array and try formatting the disks to
try and find the problem.

Under smitty ssaraid what do you see when you select:
List Status Of All Defined SSA RAID Arrays
Select RAID5 and adapter ?
Thanks,

I'm following along in the guide now se we'll see what happens.
Thanks for the suggestion.

Just as easy, go to diags and problem determination and see what SRN you get.
My best guess you have lost hot spare capability...

You can certify each disk without harming the data, within SSA task.

Yep, been there done that.  Status is good for all. 

I think I've been through all those sections and everything seems to verify as ok.

>>>pobrien@xxxxxxxxxxx 01/25/06 10:36 am >>>

How about running;

diag, go to tasks, ssa-service aids, link verification, choose your card. Look in the right column for “Good” or a clue.

I getting this in my errpt on Aix 433 server.

I know the ssa errors are being generated from the run_ssa_healthcheck script.

 

I've checked via smitty ssaraid and the status is good and not rebuilding.

 

I've also checked and I have a hot spare.

 

I've now just checked all the ssa disks via certify and nothing.

 

 

hdisk0 happens to be a scsi rootvg disk so I plan on taking down the server to cerify it as well.

 

hdisk2 is my ssa raid5 disk over 16 pdisks in a d40.

 

 

>lsdev -Cc disk

 

hdisk0 Available 10-60-00-9,0  16 Bit LVD SCSI Disk Drive

 

hdisk1 Available 10-60-00-11,0 16 Bit LVD SCSI Disk Drive

 

hdisk2 Available 10-70-L       SSA Logical Disk Drive

 

 >ssaxlate -l hdisk2

 

pdisk0 pdisk1 pdisk2 pdisk3 pdisk4 pdisk5 pdisk6 pdisk7 pdisk8 pdisk9 pdisk10 pdisk11 pdisk12 pdisk13 pdisk14

 

 

So far I can't really find anything wrong but as I said I'll take the server down later to run diags on.

 

 

Anything anyone else thinks I should look at?

 

 

Mark
