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?
