Shalom,

I've used this type of server. This is not usual behavior.

I suspect a hardware problem.

Probethe controller and dvd-rom with mstm cstm and xstm and have hardware replace the drive if problems are found.

You may wish to make sure the SAN and all hardware is working as this can be another bottleneck point.

Check for bottlenecks:

CD / DVD drive are always going to be slower than any internal drive. Compare by copying a 20mg file from each and note the time. Copying from a DVD will be maybe 10 times slower than copying from one internal drive to another. This is typical behavior.

But its take lot of time.It will takes 5 to 8 hrs for creating stage area in HP-UX.When we copy 1st DVD its take 50 mint to complete only 1O24MB and the size of the Stage is 33GB.
Steven here is the output of the script attahed.
Thanks & Regards

Bonsoir Athar,

You will not enjoy my answer :-(

I have the same behavior on most RX. IMHO I suspect it is because the DVD is connected through an USB bus. May be an OS patch or a firmware patch exists, I don't know ...

If you have an HP-UX box with an other architecture consider copying the DVD from this box onto a local disk then copying through the network to your RX6600, or directly through an NFS mount.

Hope this will help ... although my post is not very positive ;-)
