IBM i Disk system statistics

Hi Everyone!

I am the inheritor of a 9406-525 that we would like to use as a backup to our production 9406-810.

I have the system set up and running, but the disk drives keep throwing parity errors.

The new system has about 3TB of disk in the main LPAR, so I have been just pulling the bad drives out of the
array without replacing them.

My question is: Is there a way to display the error statistics for the drives in the array, so I can identify upcoming failures?

I ran the Surface Analysis about 2 weeks ago and it reported as OK.
This morning another unit reported a parity error.
That is the 4th to go bad since I brought up the system about 2 months ago.
(the array started out with 75 disks)

The system is just waiting right now, while I finish off some other projects.
The plan is to clone the applications and data, and use Journaling and remote data queues to
keep the data files up to date.

I am not inclined to load up all the files just to have the system start dropping drives.
I would like to identify the worst of the remaining drives, and remove them.
My production box only has 180GB on it, so there is plenty of room.

I am trying to pitch the i as a good platform for high availabliity, but its a tough sell with drives dropping dead left and right.

I have a bunch of Milleneals in management here who think Windows servers are the best thing, and IBM i is "legacy".

Any suggestions?

Thanks!
