>---------- End Event Monitoring Service Event Notification ----------<

The information you posted seems very clear: You really looked at that and wondered what it means? I really can't imagine how to rephase it to make it more clear. Can you tell us where you are getting lost?

Really not clear for me as I am not conforable with hp drivers, disks etc... and much more withc aix systems.
So for me it is not clear of what I have to do. I mean if I have a disk on error on aix I can check on the errpt log and see if it is missing status check with the diag commands etc... but with HP I don't know where to check if the disk is really in bad situation and need to be change etc... I receive this mail but don't know how to proceed..
I have check on docs ho and don't find anything about the disk troubleshouting.

If you can help your welcome

Sorry but I am still lost !

Thanks for your reply

Cheers

Hi again,
I have checking the disk and I have no error status on the disks ...

and check the disk with diskinfo command:

So I don't see any errors on the disk mentioned on the event notification.

There is something else that I should check ?

Thanks in advance

You should replace the disk.

Correct, you won't. This sentence: "All errors have been recovered and no data have been lost." was trying to tell you that. Just wait until the disk dies. Then you will see the errors.

ioscan detects the presence of drives. diskinfo uses a scsi command to ask the drive to describe itself.

There are diagnostics and you might be able to run them if you have them installed. See http://docs.hp.com/en/diag/stm/sth_cstm.htm

Not too sure, but iostat -En may show something as well...
