Copy 11.31 media to ISO

I'm presently trying to copy the 11.31 DVD install media into ISO format on an rx6600 so that i can use them to install HPVM's. I've used the following command on an rx8640 and an rx6600 for each DVD

dd if= of=/dvd/hpux11.31-dvd2.iso bs=2k

on the rx8640 each DVD finishes in under 10mins. however on the rx6600 it has been running for over 2hours. The only difference between the 2 DVD devices on the machines is that the rx6600 is a usb DVD. Has anyone seen this kind of behaviour from usb DVD devices?

Re: Copy 11.31 media to ISO

The current driver is much faster for USB devices than the older versions. What version do you have?

Hope this helps!

Have a look at this:

http://www11.itrc.hp.com/service/patch/patchDetail.do?patchid=PHKL_37815&sel={hpux:11.31,}&BC=main|search|

"...
This product contains enhancements required to enable USB
2.0 speeds, USB mass storage devices and USB DVD write
capability within the USB core kernel driver.

These enhancements allow CD or DVD drives connected to the
system via USB to be read faster and used for data backup.
The enhancements also add support for USB mass storage
devices such as HP supported flash memory devices.

Resolution:
- USB 2.0 hardware enabled with a new host controller
driver. This hardware is already present on any system with
USB.
- A mass storage device driver added.

Re: Copy 11.31 media to ISO

Shalom,

I think the entire process depends a lot on the type of drive. Write I/O rates to a USB write DVD are bound to be much slower than one on SCSI or IDE.

It has to do with the transfer rate to the device.

Re: Copy 11.31 media to ISO

Why not just setup a ignite server and swcopy the install media filesets to the ignite server and allow it to install the HPVMs

This is a simple relatively supportable process.

Re: Copy 11.31 media to ISO

Torsten/Steven,

you are both correct i noted that the iso file is actually being written too, it is just growing at a exceptional slow rate - i left it for a day or so and it was still going!!!. USB seems to be dead slow and that patch is not on my server.

Emil,

i appreciate your response, but the question was about copying install media to an ISO. There are always other ways of installing servers i.e. ignite, but i was not after an install mechnism (per se), i was after understanding why my iso creation worked on one server type and not another.

As it happens i created my iso on the rc8640 and scp'd it to the rx6600 and used that. i will have get that patch.
