Raid 5 Predicted Disk Faliure - HP ML350

Evening Guys

I have a client who has an HP ML350 server in a raid 5 configuration consisting of 4 disks. Two of the drives (bay's 3 & 4) are showing as a predicted failure via the HP Storage utility. We visited site today and replaced one of the disks and allowed the the array to rebuild. I just connected to the server to check on the progress and the rebuild appears to have completed however both disks are still showing a predicted failure. The plan was to visit site tomorrow to replace the final disk however I am slightly concerned that the disk we replaced today is still showing the warning.

Any ideas?

Will do Steven, we are visiting tomorrow morning so it should be enough time as the disks are small 146GB. I was planning a reboot and will look into the firmware

I just checked the firmware of the controller and its v3.0 where on the HP site v6.60 is available. Would it be ok to upgrade the firmware of the controller before replacing the final drive?

I hope you have backup of this configuration. If not then take backup and upgrade the firmware.

Hi Noxcho

Can you back the the disk configuration via the HP array software?

noxcho

Nope, you need to use either Windows Server Backup or any other third party backup tool. But this must have even if you do not have problems with the RAID controller.

I see what you mean, the server is backed up to external drive using windows backup.

Then you can start with update of firmware. Btw, in Storage Utility do you have an option to refresh the view/status of the drives?

Can you upload an ADU report so we can see the state of the other disks, I've had what look like predictive failures that are caused by other disks before and had to backup/restore.
