The systems they are doing the upgrade on are a Proliant 4500 internal storage and 2 external storage boxes one being a F1 box and the other being a UE box both connected to a Proliant 5500. I didn?t believe that all the drives were truly in a degraded state even though the drives that thay were using were used drives with about 20000 hours of drive time on them. It was recommended that I upgrade the ROM on the drives. After upgrading the drives (Aprox. 25% of the drives took the update) they tested degraded still. The next step I took was to built a test box (Proliant 5500) with external storage attached (U2 box) and test all the drives to make sure that the drives were in a good state. I tested approx. 100 drives and sorted the good from the bad but even the tested known good ones could not be swopped on the production unit. I also want to mention that the difference with the drives are that the older FW drives do not have S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). At this point I am pretty stumped on this issue, it seems there is a problem with the to types of drives being mixed on the backplane at the same time. I have reproduced the issue on the test box. (Additional info) S/N of UE box D841CDB10334 - Agent level is 4.5 on the servers ? CIM level is 4.21 ? Win NT 4.0 SP4 ? S/N Proliant 4500 6550HRX20249 ?

You can NOT hot-plug drives if you do NOT have an array controller so...

Please respond.

Also, since the 4500 can't possibly have a 3200 array controller (no PCI slots) do you know what controller that system has (had)?
