Thanks for the reply. Yes, the package included a 4-drive back-plane. Yes,
going from 4 to 8 drives. Yes, the disks are 4326.

I will try re-seating the back-plane. But is that the part you might
replace? The package included 4 disks, a back-plane, a controller, and a
battery pack.

correct?

First thing I would do is power down, pull the drives and re-seat that
part. Then put the drives back in. If that doesn't do it, replace the part.

Are the drives the same FC as the first four? i.e. 4326 or 4327? If they
are 4319s for example they are slower so that will hurt you.

I recently added 4 disk drives to our development box (9405-520), which
required a different disk controller (according to the vendor).

I installed the controller. I configured and formatted the drives and
added
them to the system ASP. They appear to work, but we're getting POOR
performance during SAVE/RESTORE operations. The system generates an error
message and problem report during IPL. I posted the error message, problem
report, and a couple screen shots:

The cache battery appears to be fine. What should be my response to the
problem?
