DFM Upgrade Very very very....slow.

Eight Physical Cores  (Physical server, not a VM)

32G RAM

Dual Path'd 4G FCP San to HP-EVA (only application on this system at the time)

EVA shows no load

The upgrade without a backup (manual backup made by hand the day before..and -it- took 11.5 hours) took about 9.5hrs to perform.

During the whole process, perfmon shows 500-2500 Disk operations in the queue, and very very little KB/sec of throughput during the last 4hrs that I was in a war-room with the users to determine why this was taking so long.

Now that it's over, user wants to know what this upgrade process is doing, to where a fast SAN system has nothing going on, no CPU load during the process (1-2% total on the Windows 2003 server) and tons of IO in the queue says perfmon.

Execution Throttle on the windows Qlogic HBA, is set to 128...moving it up makes no change it appears.

We are assuming that the same problems are in play, when the backups that months ago used to take about 2hrs to perform, now take 10-14hrs to perform..and when we test this next, we want to get data back to netapp to diagnose _what_ is going on here.

What to do next or check?
